Preparation and characterization of low expansion transparent copolyimide films

Five transparent polyimide thin films with different proportions of 1,2,4,5-,pyromellitic dianhydride (PMDA) were made by copolymerization of 4,4'-(six fluoro isopropenyl) two phthalic anhydride (6FDA), 4,4'-two amino -2,2'-double three trifluoromethyl biphenyl (TFMB) and PMDA, and th...
