聚醚砜-羟基磷灰石混合溶液的流变性能

Rheological Property of PESHAP Blend Solution

摘要: 采用N,N-二甲基乙酰胺(DMAc)为溶剂配制含羟基磷灰石(HAP)的聚醚砜(PES)溶液，研究了PES-HAP-DMAc体系的流变曲线以及HAP的质量分数、混合溶液温度等对流变性能的影响。结果表明：混合溶液的非牛顿指数（n）随着温度的升高、HAP质量分数的增大而降低，表现为非牛顿流体。

Abstract: Polyether sulfone (PES) solutions containing hydroxyapatite (HAP) were prepared with dimethyl acetamide (DMAc) as solvent. The rheological curves of the blend solution PES-HAP-DMAc, and the effects of HAP mass fraction and the temperature of the blend solution on the rheological properties were studied. Results show that nonNewtonian flow index of the blend solutions decreases with the increasing of temperature and HAP mass fraction.Overall, PES-HAP blend solution is nonNewtonian fluid.
