Research progress of hydrophobic modification for polyimide aerogels
摘要
Abstract
Polyimide aerogels,not only have excellent comprehensive properties such as high heat resistance,high strength and solvent resist-ance,but also have high specific surface area,ultra-low density and high thermal insulation,which exhibit broad applications in aerospace,e-lectronic communication,thermal insulation and other fields.However,because the molecular structure of polyimide contains a large number of hydrophilic polar groups,its thermal insulation and other performance will be significantly reduced due to water absorption.Therefore,hydro-phobic modification of polyimide aerogels is particularly necessary.In this paper,the main methods of hydrophobic modification of polyimide aerogels,such as intrinsic modification,composite modification and surface modification,as well as their application prospects and development trends were reviewed.关键词
