一、高分子液晶的发展和性质随着近代工业的发展,特别是宇航、导弹、航海和汽车工业的发展,高速和超重负载轮胎及复合材料的要求与日俱增,开发具有高强度高模量、耐辐射、耐化学腐蚀、耐高温等特种高分子材料已成为重要的研究课题。高分子液晶材料即为一类新型的特种高分子材料,已经以纤维、复合材料和注模制件等应用于航空、航海和汽车工业等部门。本文就高分子液晶的历史发展、性质与结构、合成和加工、工业化现状等作一简介。1.高分子液晶的历史高分子液晶现象的研究是基于低分子液
First, the development and nature of polymer liquid crystal With the development of modern industry, especially the aerospace, missile, marine and automotive industries, high-speed and overweight tires and composite materials requirements increase, the development of high strength and high modulus, resistance Radiation, chemical resistance, high temperature and other special polymer materials has become an important research topic. Polymer liquid crystal material is a new type of special polymer materials, has been used in fiber, composite materials and injection molding and other sectors, aviation, marine and automotive industries and other departments. This article makes an introduction to the history, nature and structure, synthesis and processing, industrialization status of polymer liquid crystal. 1. The history of polymer liquid crystal Polymer liquid crystal phenomenon is based on low molecular weight liquid
