摘要

将液晶聚酯（LCP）加入到双酚A型聚碳酸酯（PC）基体中可以显著改善体系的加工流动性，同时在复合材料中原位形成大长径比、高模量与高强度的LCP微纤，但由于PC与LCP的相容性差，导致机械性能难以大幅度提高。本文综述了LCP增强PC复合材料的研究进展，重点阐述了PC/LCP复合体系的增容技术与增强方法，并讨论了其制备工艺条件如温度、剪切速率、粘度比、拉伸比及加工次数等对LCP微纤形成与机械性能的影响。最后，通过离子化改性PC与LCP复合，以借助离子交联，增强PC基体及强的离子-偶极相互作用，实现两者之间的界面增容，从而达到真正意义上的增强，有望成为具有潜力的发展方向之一。

Abstract

Incorporation of a liquid-crystalline polyester (LCP) into a poly(bisphenol-A carbonate) (PC) matrix is able to significantly improve the processability of their composites

and meantime form the LCP microfibrils of high aspect ratio

modulus and strength in situ within them. Nevertheless

owing to the poor PC-LCP compatibility

people have met difficulties greatly enhancing the mechanical properties of the PC/LCP composites. This work has reviewed the advances in the study of LCP-reinforced PC composites

where

particularly

the compatibilization technologies as well as the reinforcement methods are explicated of the PC/LCP composite system

and the effects are discussed of its preparation process conditions

such as temperature

shear rate

viscosity ratio

draw ratio

reprocessing

etc.

on LCP microfibril formation and mechanical properties. Promisingly

it is becoming one of the potential development directions to prepare(ionized PC)/LCP composites of significant reinforcement through the strengthening of PC matrix from its ionic cross-linking and their interfacial compatibilization from strong ion-dipole interactions.
