| 摘 要： | 以LiCl饱和水溶液、醇类(甲醇和乙醇)、丙酮等小分子为添加剂，配制聚砜(PSf)／二甲基乙酰胺(DMAc)铸膜液，研究该铸膜液的粘度随添加剂的类型和含量的变化情况，重点探讨了PSf／DMAc／LiCl饱和水溶液体系的流变性能．结果表明，水及LiCl饱和水溶液对PSf／DMAc溶液具有增粘作用，而丙酮具有稀释作用，醇类介于二者之间，没有明显的增粘作用，并且稍使溶液粘度下降，PSf／DMAc／LiCl饱和水溶液体系属于切力变稀流体。

| Abstract: | The behaviors of polysulfone(PSf)/dimethylacetamide(DMAc)fluids with LiCl, alcohols, acetone as pore-forming additives were studied. Polysulfone (PSf)/dimethylacetamide(DMAc)fluids were made up and the viscosity variety of the fluids with the styles and content of the pore-forming additives, especially the rheology of PSf/DMAc/LiCl saturated aqueous solution system, were investigated. The results show that LiCl saturated aqueous solution is an effect of enhancing the viscosity for the PSf/DMAc solution, but acetone, an effect of decreasing the viscosity. The effect of alcohols is between the two. PSf/DMAc/LiCl saturated aqueous solution system is a shear thinning fluid. |
