Furthermore, we also prepared flexible algal cellulose aerogel with a low density (23 mg/cm3 ) and a high specific surface area (277 cm2 /g) after t -BuOH freeze-drying. It is also revealed that t -BuOH freeze-drying is an efficient way to assemble 1D NFC to meso- porous materials. All these results were confirmed by SEM, FTIR spectra, and X-ray diffraction profiles. On the basis of that, Ulva prolifera was nanofabrillated without any chemical purification by direct grinding, and algal foam was prepared with freeze-drying to fully use algae from green tide., authors=ZHAO Wei1 , LU Yun2 , OUYANG Huan1 , YAN Xiaomei1 , PAN Ruocai1 , YANG Dongjiang1 , SHE Xilin1 , LI Jian2 , XIA Yanzhi1 , authorsList=ZHAO Wei, LU Yun, OUYANG Huan, YAN Xiaomei, PAN Ruocai, YANG Dongjiang, SHE Xilin, LI Jian, XIA Yanzhi, authorCompany=1.

系统讨论了绿潮浒苔的独特结构和功能特性，旨在制备纳米纤丝化的海藻纤维素和高比表面积的气凝胶材料，并为浒苔的高价值应用提供新的思路。将绿潮肇事种浒苔化学纯化脱去多糖、蛋白、脂肪后，用圆盘胶磨（20000 r/min，20 min）进行纳米纤丝化，制备出均一直径（大约40 nm）和高长径比的Iα 纳米纤丝化纤维素。经由叔丁醇置换和冷冻干燥后可以制备出高比表面积（277 cm2 /g）、密度为23 mg/cm3 的柔性纳米纤丝化纤维素气凝胶。所有这些结果通过扫描电镜（SEM）、红外光谱仪（FTIR）、X射线衍射仪（XRD）进行分析。在此基础上，采用机械法直接用胶体磨将浒苔原料进行纳米纤丝化，冷冻干燥后制备出全组分的浒苔泡沫材料。
