The blending ratio of DMAc to NMP was 8:2 in the mixed solvent. The effects of temperature and PEG concentration on the rheological and thermodynamic properties of the PSF casting solution were studied quantitatively based on the casting-solution viscosity measurement by Rotational Rheometer and the cloud-point phase diagram obtained by Cloud-point Titration. It is found that the PSF solution with PEG additive is Newtonian fluid in the examination scope (shear rate from 0 to 100 s-1). The viscosity of the PSF casting solution was obtained via linear regression between shear rate and shear stress. The viscosity of PSF casting solution increases with the increase of the PEG concentration and with the decrease of the temperature. PEG reduces the miscibility of the PSF solution with non-solvent, leading to thermodynamic enhancement for phase inversion, but temperature increase can increase the miscibility of the PSF solution with non-solvent, therefore, it can decelerate the phase inversion of the PSF casting solution., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=以N,N-二甲基乙酰胺（DMAc）和N-甲基-2-吡咯烷酮（NMP）为混合溶剂，以聚乙二醇（PEG）为添加剂制备聚砜（PSF）铸膜液，采用旋转流变仪测定PSF铸膜液黏度，采用浊点滴定法绘制浊点相图，定量研究了温度和PEG浓度对聚砜铸膜液流变学和热力学性质的影响。在剪切速率0～100 s-1范围内，对铸膜液剪切速率和剪切应力的检测值进行拟合，得知聚砜铸膜液为牛顿流体，进而求出聚砜铸膜液的黏度值。结果表明，聚砜铸膜液黏度随PEG浓度的增大而增大，随温度的升高而减小。PEG减弱了铸膜液对非溶剂的容纳能力，加速铸膜液的液-液相分离；温度升高可增大铸膜液对非溶剂的容纳能力，减缓铸膜液的液-液相分离。, authors=郑庆柱¹,田侠¹,王鹏²,
