摘要

聚酰亚胺(PI)微球因其微纳结构所赋予独特的物理化学性质而受到广泛的关注。本研究采用相反转乳化法实现对PI的微球化，制备的PI微球具有单分散特性。研究结果表明，PI分子结构中引入疏水基团有利于微球化，搅拌速度和乳化剂浓度影响PI微球的形貌及粒径分布。

Abstract

Owing to their unique physicochemical properties endowed by the micro/nano structure

polyimide microspheres attracted many attentions. Polyimide microspheres were fabricated via phase inversion emulsification method. The polyimide microspheres prepared by this way were mono-dispersed. PI with hydrophobic group in the molecular structure could be fabricated into microspheres in the microstructure successfully. Stirring rates and emulsion concentrations influenced polyimide microspheres morphology and particle distribution severely.
