| Abstract: | A series of poly(amide acid)s(PAAs) and polyimides(PIs) were synthesized with pyromellitic dianhydride(PMDA) and 1,4-phenylenediamine(PDA) using two-step method at low temperature and its structures were characterized with FTIR.The results showed the formation of poly(amide acid)s and polyimides and the better imidization.The PMDA-PDA PI thin film possesses a high tensile strength up to 290 MPa. |
