摘要

采用流变学方法研究了聚偏氟乙烯(PVDF)溶液在nmethylpyrroli酮中的流变性能。结果表明，聚合物溶液的粘度随温度的升高呈非线性降低。用作溶剂的n -甲基吡咯烷酮的粘度几乎保持不变。结果表明，溶液在浓度低于7 wt.%时表现出牛顿行为。在较高浓度下，溶液表现出假塑性流体的特性

Rheological Properties of PVDF Solutions

The rheological properties of polyvinylidene fluoride (PVDF) solutions in Nmethylpyrrolidone were studied using the rheometric method. It was shown that the viscosity of polymer solutions decreases non-linearly with increasing temperature. The viscosity of the N-methylpyrrolidone used as solvent remains practically unchanged. It was shown that solutions exhibit Newtonian behaviour at concentrations less than 7 wt.%. At higher concentrations, solutions exhibit properties of pseudoplastic fluid
