摘要：The copolyimide/MWCNTs-COOH composites were synthesized by pyromellitic dianhydride (PMDA), 3,3'4,4'-biphenyltetracarboxylic dianhydride (BPDA), 4,4'-diaminodiphenyl ether (ODA) and the carboxylated multiple-walled carbon nanotubes (MWCNTs-COOH) through ultrasonic dispersion in situ polymerization. And the mechanical and thermal properties of the composite films were studied. The results showed that the carbon nanotubes were well dispersed in the polyimide composite films, the tensile properties and thermal stability were improved significantly.
