Four fluorene-containing polyimide (PI) resins without per- and polyfluoroalkyl substances (PFAS), including PI-Ia (BPAF-BAOFL), PI-IIa (BPFDA-BAOFL), PI-Ib (BPAF-FDAADA), and PI-IIb (BPFDA-FDAADA) were prepared from two fluo-rene-containing dianhydrides 9,9-bis[(3,4-dicarboxy)benzene]fluorene dianhydride (BPAF, I) and 9,9-bis[4-(3,4-dicarboxyphenoxy)phenyl]fluorene dianhydride (BPFDA,II) and the fluorene-containing diamines 9,9-bis[(4-aminophenoxy)phenyl]fluorene (BAOFL,a) and 9,9-bis[4-(4-aminobenzamide)phenyl]fluorene (FDAADA,b), respectively via two-step chemical imidization procedure. The corresponding PI films were prepared by the solution processing procedure. The results show that the derived PI resins show good solubility in polar N-methyl-2-pyrrolidone (NMP), N,N-dimethylacetamide (DMAc) and cyclopentanone (CPA). The incorporation of fluorene substituents endows the PI films good thermal resistance with the glass transition temperatures (Tg) over 298℃. The BAOFL-based PI films (PI-Ia and PI-IIa) exhibit low dielectric features with the dielectric constants (Dk) and dielectric dissipation factors (Df) in the range of 2.87 to 3.20 and 0.006 6 to 0.012 3, respectively at 10 GHz. While the FDAADA-based PI films (PI-Ib and PI-IIb) shows a bit deteriorated dielectric feature due to the existence of polar amide units (-CONH-). However, the high-temperature dimensional stability of the FDAADA-based PI films is improved with the linear coefficient of thermal expansion (CTE) values as low as 38.9×10-6 K-1.

采用含芴基二酐单体9,9-双[(3,4-二羧基)苯基]芴二酐(BPAF,I)以及9,9-双[4-(3,4-二羧基苯氧基)苯基]芴二酐(BPFDA,II)分别与含芴基二胺单体9,9-双[(4-氨基苯氧基)苯基]芴(BAOFL,a)以及9,9-双[(4-氨基苯甲酰胺基)苯基]芴(FDAADA,b)通过两步化学亚胺化工艺制备了4种不含全氟与多氟烷基物质(PFAS)的含芴型聚酰亚胺(PI),包括PI-Ia(BPAF-BAOFL)、PI-IIa(BPFDA-BAOFL)、PI-Ib(BPAF-FDAADA)和PI-IIb(BPFDA-FDAADA),并采用溶液加工工艺制备了相应的PI薄膜。结果表明:PI树脂在N-甲基吡咯烷酮(NMP)、N,N-二甲基乙酰胺(DMAc)、环戊酮(CPA)等极性有机溶剂中均具有良好的溶解性。芴基的引入赋予了PI薄膜良好的耐热稳定性,玻璃化转变温度(Tg)超过298℃。基于BAOFL的PI-Ia与PI-IIa薄膜显示出低介电特性,在10 GHz频率下的介电常数(Dk)介于2.87~3.20,而介电损耗因子(Df)介于0.006 6~0.012 3。基于FDAADA的PI-Ib与PI-IIb薄膜由于极性酰胺键(-CONH-)的引入显示出较高的DkDf值,但同时表现出更优的高温尺寸稳定性,其线性热膨胀系数(CTE)低至38.9×10-6 K-1

采用含芴基二酐单体9,9-双[(3,4-二羧基)苯基]芴二酐(BPAF,I)以及9,9-双[4-(3,4-二羧基苯氧基)苯基]芴二酐(BPFDA,II)分别与含芴基二胺单体9,9-双[(4-氨基苯氧基)苯基]芴(BAOFL,a)以及9,9-双[(4-氨基苯甲酰胺基)苯基]芴(FDAADA,b)通过两步化学亚胺化工艺制备了4种不含全氟与多氟烷基物质(PFAS)的含芴型聚酰亚胺(PI),包括PI-Ia(BPAF-BAOFL)、PI-IIa(BPFDA-BAOFL)、PI-Ib(BPAF-FDAADA)和PI-IIb(BPFDA-FDAADA),并采用溶液加工工艺制备了相应的PI薄膜。结果表明:PI树脂在N-甲基吡咯烷酮(NMP)、N,N-二甲基乙酰胺(DMAc)、环戊酮(CPA)等极性有机溶剂中均具有良好的溶解性。芴基的引入赋予了PI薄膜良好的耐热稳定性,玻璃化转变温度(Tg)超过298℃。基于BAOFL的PI-Ia与PI-IIa薄膜显示出低介电特性,在10 GHz频率下的介电常数(Dk)介于2.87~3.20,而介电损耗因子(Df)介于0.006 6~0.012 3。基于FDAADA的PI-Ib与PI-IIb薄膜由于极性酰胺键(-CONH-)的引入显示出较高的DkDf值,但同时表现出更优的高温尺寸稳定性,其线性热膨胀系数(CTE)低至38.9×10-6 K-1

Four fluorene-containing polyimide (PI) resins without per- and polyfluoroalkyl substances (PFAS), including PI-Ia (BPAF-BAOFL), PI-IIa (BPFDA-BAOFL), PI-Ib (BPAF-FDAADA), and PI-IIb (BPFDA-FDAADA) were prepared from two fluo-rene-containing dianhydrides 9,9-bis[(3,4-dicarboxy)benzene]fluorene dianhydride (BPAF, I) and 9,9-bis[4-(3,4-dicarboxyphenoxy)phenyl]fluorene dianhydride (BPFDA,II) and the fluorene-containing diamines 9,9-bis[(4-aminophenoxy)phenyl]fluorene (BAOFL,a) and 9,9-bis[4-(4-aminobenzamide)phenyl]fluorene (FDAADA,b), respectively via two-step chemical imidization procedure. The corresponding PI films were prepared by the solution processing procedure. The results show that the derived PI resins show good solubility in polar N-methyl-2-pyrrolidone (NMP), N,N-dimethylacetamide (DMAc) and cyclopentanone (CPA). The incorporation of fluorene substituents endows the PI films good thermal resistance with the glass transition temperatures (Tg) over 298℃. The BAOFL-based PI films (PI-Ia and PI-IIa) exhibit low dielectric features with the dielectric constants (Dk) and dielectric dissipation factors (Df) in the range of 2.87 to 3.20 and 0.006 6 to 0.012 3, respectively at 10 GHz. While the FDAADA-based PI films (PI-Ib and PI-IIb) shows a bit deteriorated dielectric feature due to the existence of polar amide units (-CONH-). However, the high-temperature dimensional stability of the FDAADA-based PI films is improved with the linear coefficient of thermal expansion (CTE) values as low as 38.9×10-6 K-1.

随着人类社会信息化程度的不断提升,对于获取信息的时效性与速度要求越来越高。这就要求通信装备可以高速稳定地传输各种信号,包括电信号、光信号等。为此,信号传输的延迟与损耗问题得到了越来越广泛的重视[1-3]。研究显示,对于电信号的传输,其延迟与损耗主要与信号传输频率(f)以及器件内部各种介质材料的介电常数(Dk)与介电损耗因子(Df)有关。在高频信号传输成为主流的今天,要实现脉冲电信号传递的高速化,要求所用绝缘介质材料应具有尽可能低的DkDf[4-6]。此外,为了适应第5代(5G)、第6代(6G)移动通信技术的应用需求,所使用的绝缘介质材料还需要具有足够的机械强度以支撑多层连线的架构、高杨氏系数、高击穿电压、低漏电、高热稳定性、低吸水性、与各种基材间良好的粘合强度以及与化学机械抛光等工艺良好的兼容性等。在此背景下,兼具低介电常数(low-Dk)与低介电损耗因子(low-Df)的有机高分子绝缘介质的研究与开发得到了学术界与工业界的广泛关注。近年来,该领域的研究已有多篇综述报道[7-11]
聚酰亚胺(PI)是目前可满足上述性能需求的理想候选材料之一[12]。PI介质材料特有的刚性酰亚胺环骨架结构可赋予其优良的耐高温、高力学、高绝缘、高粘接力等特性。虽然标准型PI介质材料尚存在吸水率高、高温高湿环境下绝缘性能易劣化以及DkDf值偏大等性能缺陷,但PI介质材料分子结构可设计性强、灵活度高,可有效弥补上述缺陷,各种改性型PI(MPI)介质材料应运而生。皇甫梦鸽等[13]基于经典Clausius-Mossotti方程总结了low-Dk高分子材料的结构与组成设计思路,提出了引入低摩尔极化率(P)和高摩尔体积(V)基团来降低PI薄膜Dk值的方案,并对含氟型与非氟型低介电PI薄膜的发展状况进行了综述。同济大学的HE X等[14]从分子模拟以及实验验证角度揭示了PI薄膜的高频介电损耗影响机制。结果表明,酯基的引入对PI薄膜的Df值影响较为显著,酯基数量、取代位置、侧基和分子间相互作用均会对PI薄膜的介电损耗产生影响。例如,在高频(10 GHz)下PI薄膜的Df值随着酯基数量的增加而降低;对于同分异构的含酯基PI薄膜而言,将酯基引入二酐可显著降低Df值;苯环与酯基之间的键合方式方面,具有醚键连接的异构体显示出更低的Df值等。另一方面,将氢键引入PI薄膜中则可能会对降低其Df值产生负面影响。日本学者M HASEGAWA[15-17]的研究工作进一步验证了上述含酯基PI薄膜的结构与Df关系。
目前,关于low-Dk与low-Df型PI薄膜的研究主要是集中在含氟型材料方面,氟化是实现PI薄膜低介电化最为重要的手段之一[18-21]。C-F键的低摩尔极化率特性可使其有效降低PI薄膜的Dk值,同时C-F键的高电负性还可有效抑制PI分子链内部及分子链间的电荷转移(CT)作用,进而减少对可见光信号的吸收,使得在获得low-Dk材料的同时还可赋予含氟型PI薄膜优良的光学性能。这种一举两得的改性效果使得含氟型PI(FPI)薄膜不仅在微电子领域中获得了广泛的应用,同时在光电领域中的应用也备受青睐。但近年来在高性能高分子材料研究与开发方面越来越多地受到全氟与多氟烷基物质(PFAS)法案的限制。PFAS物质广泛存在于人类的生产与生活中[22]。近年来的研究显示,PFAS物质具有高度的环境持久性,同时具有生物蓄积性和毒性,对水环境、土壤乃至人类健康会产生深远的影响。为此,国际上关于禁用PFAS的呼声日益高涨[23]。PFAS禁令对FPI薄膜的发展具有一定的影响,尤其是在与人类生产和生活息息相关的微电子、光电显示以及通信等领域[24]。服务于上述领域的low-Dk与low-Df型FPI薄膜的研制与开发不得不考虑PFAS的潜在影响。
本文针对先进微电子领域对于低介电型PI薄膜材料的应用需求,拟开展兼具low-Dk、low-Df、耐高温、良好尺寸稳定性以及可采用溶液工艺成膜的无氟型PI薄膜的结构设计、合成与性能研究工作,旨在将芴(fluorene)取代基引入PI薄膜分子结构中,研究芴基的引入对PI薄膜耐热性能与介电性能的影响。
含芴基二酐单体,包括9,9-双[(3,4-二羧基)苯基]芴二酐(BPAF)以及9,9-双[4-(3,4-二羧基苯氧基)苯基]芴二酐(BPFDA),纯度≥99.5%,天津众泰材料科技有限公司,使用前需在180℃真空干燥24 h。含芴基二胺单体,包括9,9-双[(4-氨基苯氧基)苯基]芴(BAOFL)以及9,9-双[(4-氨基苯甲酰胺基)苯基]芴(FDAADA),纯度≥99.5%,中国台湾士锋科技有限公司,直接使用。无水N,N-二甲基乙酰胺(DMAc)、N,N-二甲基甲酰胺(DMF)、环戊酮(CPA)、甲苯、无水乙醇等其他试剂,分析纯,北京伊诺凯科技有限公司,直接使用。
以PI-Ia(BPAF-BAOFL)为例说明PI树脂的合成过程。搭建一套500 mL装配机械搅拌、冷水浴以及氮气保护装置的三口瓶聚合装置。首先,加入无水DMAc(150.0 g),通入氮气。然后,在搅拌下加入二胺BAOFL(26.632 0 g,50 mmol),室温下搅拌10 min后得到清亮的二胺溶液。随后,将二酐单体BPAF(22.921 5 g,50 mmol)一次性加入到上述二胺溶液中。用无水DMAc(48.2 g)清洗称量纸,保障所有单体加入到聚合装置中,得到固含量约为20%的聚合溶液。室温搅拌反应24 h后得到黏稠的聚酰胺酸(PAA)溶液,期间再加入无水DMAc(82.6 g),将固含量降低为15%。在此溶液中加入乙酸酐(150 g)和吡啶(0.5 g),室温下继续搅拌24 h,得到浅棕色黏稠PI溶液。将制得的PI溶液缓慢沉淀在乙醇水溶液(75%)中,得到浅棕色丝状沉淀。采用无水乙醇浸泡2遍,每遍24 h。最后将树脂过滤收集,经自然风干、80℃真空干燥24 h后,得到PI-Ia树脂46.4 g,收率为97.2%。其他PI树脂,包括PI-IIa、PI-Ib和PI-IIb参照表1所示配方并采用类似的工艺制备。
将PI-Ia树脂(15 g)与无水DMAc(60 g)混合后,置于100 mL三口瓶中,在室温下搅拌过夜,得到浅棕色黏稠PI-Ia溶液(固含量为20%)。将该溶液过滤纯化后,采用刮刀涂覆在洁净的玻璃基板上。随后将玻璃基板置于氮气环境的烘箱中,经80℃/1 h+120℃/1 h+150℃/1 h+180℃/1 h+250℃/1 h+280℃/1 h热处理后,降至室温。最后,将玻璃基板浸泡于去离子水中,浅棕色的薄膜从玻璃基板上自然脱落,再将其置于120℃鼓风干燥箱中处理3 h,最终得到浅棕色PI-Ia薄膜。
其他薄膜,包括PI-IIa、PI-Ib、PI-IIb均采用类似的工艺制备。

PI薄膜:傅里叶变换红外光谱(FTIR)采用FTIR光谱仪(Tensor-27型,德国Bruker)测试,波数范围为4 000~400 cm-1。紫外可见光谱(UV-Vis)通过紫外可见分光光度计(U-3210型,日本日立公司)测试。CIE Lab颜色参数通过分光光度计(Ci7800型,美国X-rite公司)测试,薄膜厚度为25 μm,分别记录L*(亮度),红-绿参数(a*)、黄-蓝参数(b*)以及雾度(haze)。折射率,包括面内折射率(nTE)、面外折射率(nTM)通过棱镜耦合仪(Model 2010/M型,美国Metricon公司)测试,测试波长为632.8 nm。平均折射率(nav)按照nav=[(2nTE2+nTM2)/3]1/2计算,双折射率(Δn)按照Δn=nTE-nTM计算。热分解温度通过热重分析仪(TGA,STA-8000型,美国Perkin-Elmer公司)测试,测试温度为30~760℃,升温速率为20℃/min,测试环境为氮气。玻璃化转变温度(Tg)通过动态机械分析仪(DMA,242E型,德国耐驰公司)测试,测试温度为30~350℃,升温速率为5℃/min,测试环境为氮气,Tg采用损耗角正切(tanδ)曲线峰值温度判定。线性热膨胀系数(CTE)通过热机械分析仪(TMA,402F3型,德国耐驰公司)测试,升温速率为10℃/min,测试温度为30~400℃,结果取第二遍测试的50~200℃线性范围内的数据。介电常数(Dk)与介电损耗(Df)通过采用网格分析仪(E5063A型,美国安捷伦公司)测试,测试温度为室温,相对湿度为51%,频率为10 GHz,样品尺寸为5 cm×12 cm× 0.025 mm,采用5个平行样品测试数据的平均值。PI薄膜的吸水率(W)按照文献[27]采用重量法进行测试,具体流程如下:将尺寸为20 mm×20 mm×0.025 mm的薄膜样品(质量为W1)置于去离子水中(20℃)至恒重状态,测试最终薄膜样品质量(W2),并按照W=(W2-W1)/W1×100%计算吸水率。
图1为PI树脂的合成示意图。本研究工作的主要目的是探索PFAS-free型溶液可加工性低介电PI薄膜的结构设计、合成以及结构-性能研究。为了实现上述目标,设计了如图1所示结构的PI树脂。该系列PI树脂在结构上的共同点均采用了含有庞大芴取代基的聚合单体;而差异则主要在于二酐单体方面,分别选择了芴二酐BPAF以及醚键连接的芴二酐BPFDA;二胺单体则分别选择了醚键连接的芴二胺BAOFL以及酰胺键连接的芴二胺FDAADA。芴基在降低PI薄膜Dk方面的研究文献已多有报道[28]。芴基的引入之所以能降低高分子薄膜材料Dk主要得益于其庞大的摩尔体积(V)。虽然其摩尔极化率(P)不属于低水平范畴,但P/V具有较低的水平,这可有效降低高分子材料的Dk值,同时还可改善高分子材料的溶解性、疏水性、折射率、玻璃化转变温度(Tg)以及光学性能等[29-30]。虽然三氟甲基(-CF3)、六氟异丙基(-C(CF3)2)等基团也可获得类似效果,但在PFAS法案逐渐得到重视的当前,这些含氟基团的使用会逐步受到限制。研究人员重新将目光投向了芴基这类取代基。
实验显示,4种PI体系在聚合过程中,尤其是化学亚胺化过程中均未出现凝胶化或者沉淀等现象,表明制备的PI树脂在聚合溶剂中具有良好的溶解性。PI树脂的GPC测试结果如图2表2所示。从图2表2可以看出,对于同一种二酐单体而言,基于二胺BAOFL的PI树脂较基于FDAADA的PI树脂表现出更高的数均分子量(Mn)。例如,PI-Ia(BPAF-BAOFL)的Mn=18.92×104 g/mol,而PI-Ib(BPAF-FDAADA)的Mn=3.15×104 g/mol。PI-IIa(BPFDA-BAOFL,Mn=6.21×104 g/mol)以及PI-IIb(BPFDA-FDAADA,Mn=4.13×104 g/mol)也表现出类似的规律。这主要是由于FDAADA二胺分子结构中,氨基对位的酰胺键羰基具有较强的吸电子能力,因此降低了氨基上的电子云密度,使得FDAADA的聚合反应活性低于BAOFL。而BAOFL氨基对位的醚键具有一定的供电子能力,从而使得BAOFL在聚合时更易获得高分子量树脂。4种PI树脂的分子量多分散指数(PDI)介于1.45~2.06,显示出相对较窄的分子量分布,表明现有聚合反应条件适用于该系列树脂的制备。总而言之,本研究制备的PI树脂均具有较高的分子量,这对于后续薄膜制备具有积极的影响。
4种PI树脂在有机溶剂中的溶解性测试结果也列于表2中,可以看出,庞大的芴取代基、柔性醚键等基团赋予了PI树脂良好的溶解性。所有树脂在NMP、DMAc、DMF和二甲基亚砜(DMSO)等极性非质子性溶剂以及环戊酮(CPA)中均具有良好的溶解性。除了PI-Ib树脂外,其他树脂还可溶解于四氢呋喃(THF)中。这主要是因为PI-Ib树脂中刚性酰胺键的存在以及柔性醚键的缺失使其在有机溶剂中的溶解性下降。芴以及醚键等取代基的存在可显著降低PI分子链的堆砌密度,减少有序结构和结晶的发生,从而有利于溶剂的渗透。这一点可从图3 PI树脂的XRD测试结果看出。如图3所示,所有树脂在10°~90°的衍射角(2θ)扫描范围内未观察到显著的结晶峰,表明4种PI树脂具有典型的无定型结构特征。总而言之,PI树脂在有机溶剂中良好的溶解性赋予了这类树脂良好的溶液可加工特性。
采用核磁氢谱(1H-NMR)表征PI树脂的结构,典型的PI-Ib与PI-IIb树脂的测试结果如图4所示。两种PI树脂的H质子在1H-NMR谱图中均可准确地加以指认。从图4可以看出,两种树脂分子结构中,酰胺键H质子(H10)的吸收均出现在谱图的最低场位置。二酐单元酐基邻位取代H质子(PI-Ib:H1与H3;PI-IIb:Hb)受酐基强吸电子特性的影响,其吸收出现在谱图的次低场位置。对于无醚键的PI-Ib树脂而言,除了溶剂与溶剂水吸收峰外,H12的吸收出现在谱图的最高场位置,而对于含有醚键的PI-IIb树脂而言,醚键邻位取代H质子(H1与H2)的吸收出现在谱图的最高场位置。对于苯环与芴环上的H质子,由于其所处化学环境较为详细,其吸收叠加在一起,出现在谱图的7.0~8.0位置。以上信息符合PI树脂的分子结构特征,表明本研究制得了预期结构的PI树脂。
采用溶液加工工艺制备了相应的PI薄膜。由于PI树脂已经亚胺化,制膜过程主要是以烘烤溶剂为主的物理过程。该过程在最高温度为280℃时充分完成,最终得到了一系列PI薄膜。首先采用FTIR手段表征PI薄膜的化学结构,结果如图5所示。从图5可以看出,对于FDAADA基PI薄膜(PI-Ib与PI-IIb)而言,在3 642 cm-1处观察到酰胺键(-CONH-)的特征吸收峰,同时在1 674 cm-1处清晰地观察到酰胺键羰基的特征吸收峰,而这两处吸收峰在BAOFL基PI薄膜(PI-Ia与PI-IIa)的谱图中是没有的。此外,对于PI-Ia、PI-IIa和PI-IIb薄膜而言,在1 240 cm-1处可显著观察到醚键(-C-O-C-)的特征吸收峰,而该吸收峰在PI-Ib谱图中则很微弱。对于4种PI薄膜而言,其共同的吸收峰包括:位于3 062 cm-1处的苯环不饱和C-H键振动吸收峰,分别位于1 780、1 725、736 cm-1处的酰亚胺环羰基的不对称伸缩振动吸收峰、对称伸缩振动吸收峰、弯曲振动吸收峰,位于1 376 cm-1处的酰亚胺环C-N键振动吸收峰,以及位于1 500 cm-1处的苯环C=C键伸缩振动吸收峰等。上述信息均符合PI薄膜的化学结构,表明制得了预期结构的PI薄膜。
虽然优良的光学性能不是本研究所追求的主要目标,但光学性能的差异在一定程度上可反映PI薄膜的结构与性能关系。因此本研究测试了PI薄膜的紫外-可见光谱、CIE Lab光学参数以及折射率等参数,结果如表3所示。图6为PI薄膜的UV-Vis谱图。从表3图6可以看出,BAOFL基PI薄膜(PI-Ia与PI-IIa)表现出优于FDAADA基PI薄膜(PI-Ib与PI-IIb)的光学性能,主要表现在紫外截止波长(λcut)和450 nm波长处的透光率(T450)上。例如,PI-Ia薄膜的λcutT450值分别为373 nm和75.7%,分别优于结构类似的PI-Ib薄膜(λcut=380 nm、T450=55.4%)。CIE Lab光学参数方面也显示出类似的规律。例如,PI-Ia薄膜的亮度(L*)、黄度指数(b*)与雾度分别为94.32、11.27和1.33%,也分别优于结构类似的PI-Ib薄膜(L*=91.90、b*=18.21、雾度=5.11%)。这主要是由于FDAADA基PI薄膜分子结构中极性酰胺键(-CONH-)的存在对可见光信号会产生较为显著的吸收。
折射率测试结果也较好地揭示了PI薄膜的结构与性能的关系。4种PI薄膜的平均折射率(nav)均超过1.66,同时超过了常规的含氟型PI薄膜(nav≈1.50~1.62)[31],而且平均折射率(nav)按照PI-IIa、PI-Ia、PI-IIb、PI-Ib的顺序依次升高,表明芴基的引入可显著提升PI薄膜的折射率,这与芴基较高的摩尔体积密切相关。折射率的提升意味着制备的光学部件可以实现更薄的厚度,有利于光学部件的薄型化和轻量化[32]。此外,FDAADA基PI薄膜表现出更高的nav值。这主要是由于极性酰胺键(-CONH-)具有较高的摩尔折射率。同时,刚性平面酰胺键的存在使得FDAADA基PI薄膜分子链内部存在局部有序结构,使其薄膜的双折射率(Δn)有所升高,超过了0.01。而BAOFL基PI薄膜由于分子链有序度较低,表现出超低的Δn值。其中,PI-IIa薄膜的Δn值仅为0.005 4,这对于其作为光学材料使用十分有利。
PI薄膜优良的耐热性能是保障其在实际应用中具有高可靠性的重要因素。为此,采用TGA、DMA以及TMA手段评价了4种PI薄膜的耐热稳定性,结果总结于表4中,图7为PI薄膜的TGA及相应的微分TGA(DTG)谱图。从表4图7可以看出,PI薄膜的热分解主要发生在450℃以后,显示出良好的耐热稳定性。4种PI薄膜的5%失重温度(T5%)按照PI-IIb、PI-Ib、PI-IIa、PI-Ia的顺序依次升高,表明FDAADA基PI薄膜的耐热稳定性稍差于结构类似的BAOFL基PI薄膜,这一点从DTG曲线上也可以明显看出。例如,FDAADA基PI薄膜在受热过程中发生了两次显著的热分解过程。第1个过程对应的分解速率最快时的温度(Td1max)约为520℃,主要由酰胺键的热分解造成,而第2次热分解对应的分解速率最快时的温度(Td2max)约为590~602℃,主要由PI薄膜主链结构的分解造成。同等条件下,BAOFL基PI薄膜只显示出单次热分解行为。所有PI薄膜在750℃时的残余质量分数(Rw750)均超过66%,显示出良好的耐热性能。
采用DMA手段测试了PI薄膜的玻璃化转变温度,结果如图8所示。DMA曲线记录了PI薄膜的储能模量(E′)与损耗模量(E″)随测试温度的升高而发生变化的情况,同时记录了损耗角正切tanδ随温度的变化情况,其峰值温度可记为PI薄膜的玻璃化转变温度(Tg, DMA)。从图8可以看出,4种PI薄膜的Tg, DMA值按照PI-IIa(298.8℃)、PI-IIb(355.9℃)、PI-Ia(364.5℃)、PI-Ib(439.1℃)的顺序依次升高。分子结构中具有最高柔性醚键含量的PI-IIa薄膜显示出最低的Tg, DMA值,而分子结构中不含有柔性醚键的PI-Ib薄膜显示出最高的Tg, DMA值,这与PI薄膜的结构特征一致。此外,由PI薄膜的Tg, DMA值可以看出,庞大芴基的引入可有效阻碍高温下PI分子链段的自由运动,从而赋予PI薄膜较高的热稳定性。超过298℃的Tg, DMA值对于保障PI薄膜在微电子或光电领域中的高可靠性是十分有利的。
采用TMA手段考察了PI薄膜的热膨胀行为,并记录了PI薄膜在50~200℃范围内的线性热膨胀系数(CTE),结果如图9所示。从图9可以看出,随着测试温度的升高,所有PI薄膜首先均表现出线性膨胀行为。当温度达到或接近PI薄膜的Tg值时,PI薄膜开始显示出收缩的趋势。对于Tg值最低的PI-IIa薄膜,这种收缩现象表现更明显。这主要是由于薄膜制备的温度最高为280℃,低于薄膜本身的Tg值。因此当温度超过280℃并接近薄膜的Tg温度点时,薄膜会产生显著的残余应力释放现象,表现为尺寸收缩[33]。当薄膜内部的应力释放完全后,随着温度的进一步升高,薄膜表现为正常的膨胀现象。按照PI薄膜在50~200℃温度范围内的线性膨胀情况,可以得出PI薄膜的CTE值按照PI-Ib(38.9×10-6 K-1)、PI-Ia(44.0×10-6 K-1)、PI-IIb(48.1×10-6 K-1)、PI-IIa(53.4×10-6 K-1)的顺序依次升高。结果表明,同样是柔性醚键含量最高的PI-IIa薄膜显示出最高的CTE值,而柔性醚键含量最低的PI-Ib薄膜则显示出最低的CTE值。此外PI-Ib薄膜分子结构中的刚性酰胺键也可显著降低其CTE值。对于PI薄膜而言,在微电子与光电器件应用中,具有低的CTE值是十分必要的,可以有效防止由于PI薄膜的CTE与常见无机非金属材料之间CTE的不匹配而造成的可靠性问题[34]。但大多数情况下,降低PI薄膜CTE的改性措施均是以牺牲材料的溶解性、光学性能、介电常数与介电损耗为代价的。而有机-无机杂化是解决这个矛盾的有效手段。对于本研究的PI薄膜,尤其是BAOFL基PI薄膜而言,未来与low-CTE型无机纳米粒子复合将是降低CTE的有效途径。
最后评价了PI薄膜的介电性能,PI薄膜在10 GHz频率下的DkDf值列于表4。PI薄膜的Dk值按照PI-IIa(2.87)、PI-Ia(3.20)、PI-IIb(3.33)、PI-Ib(3.62)的顺序依次升高。PI薄膜Df值的变化也表现出类似的规律,即按照PI-IIa(0.006 6)、PI-Ia(0.012 3)、PI-IIb(0.021 1)、PI-Ib(0.037 5)的顺序依次增大。由此可见,含有极性酰胺键的FDAADA基PI薄膜(PI-Ib与PI-IIb)显示出相对较高的DkDf值,这一方面是由于极性酰胺键较高的摩尔极化率,同时极性酰胺键对于水汽较为敏感,而水汽的吸附会在一定程度上劣化PI薄膜的介电性能。这一点从表4中PI薄膜的吸水率(W)数据可以得到验证,含有酰胺键的PI-Ib与PI-IIb薄膜显示出明显高于PI-Ia与PI-IIa薄膜的吸水率。综上,BAOFL基PI薄膜表现出较好的介电性能,尤其是PI-IIa薄膜同时显示出较低的DkDf值。这主要归于高摩尔体积芴基以及低摩尔极化率醚键等基团的协同作用。优良的介电特性对于PI-IIa薄膜作为微电子器件绝缘介质的应用是十分有利的。
针对先进微电子器件对于低介电绝缘介质材料的迫切应用需求,同时考虑到含氟型PI薄膜面临的PFAS禁令冲击,本研究设计并合成了一系列芴基取代PI薄膜,通过研究薄膜的结构与性能关系,得到如下结论:
(1)芴基的引入能够赋予PI薄膜优良的溶液可加工特性与耐热稳定性,使Tg超过298℃,但同时会在一定程度上提高薄膜的热膨胀系数,并增大薄膜的折射率。
(2)芴基与醚键的引入可赋予PI薄膜良好的介电性能,在10 GHz测试频率下,PI-IIa薄膜的DkDf值分别为2.87和0.006 6。
(3)PI-IIa薄膜显示出良好的综合性能,未来与无机纳米粒子复合后有望在先进微电子领域中得到应用。
