摘要

Abstract

Experimental studies were undertaken to investigate glass transition temperature,thermal conductivity at static temperature and performance of thermal insulation at dynamic temperature of 4 kinds for aromatic polyimide foams by DMTA and self-made apparatus. The relationship of density,temperature between thermal conductivity of polyimide foams and performance of thermal insulation of polyimide foams at dynamic temperature were examined. The results show that stiffness of monomer (especially diamine) has influence on glass transition temperature of polyimide foams; the density of polyimide foams ranging from 50-140kg/m3 has little influence on thermal conductivity; with static temperature ranging from 50-350℃ rising, thermal conductivity of polyimide foams are also rising; at dynamic temperature, polyimide foams show hysteretic nature obviously.
