| Abstract: | Polyimide(PI) electrical conductive composites were prepared from the corresponding PI precursor and electrical conductive fillers under the names of carbon nanotubes(CNTs),graphite and acetylene black by solution cast and subsequent heat amidation.The polyimide precursor,poly(amic acid)(PAA),was synthesized from 3,4,3′,4′-biphenyltetracar-boxylic dianhydride(BPDA) and 4,4’-diaminodiphenyl ether(ODA) with intense mechanical stirring at-5 ℃.Scanning electron microscope(SEM),electronic stretching tester,digital ohmmeter was used to characterize the electrical,mechanical and adhesive properties of the as-prepared PI electrical conductive composites,respectively.The experimental results show that the electrical conductive composite of PI/CNTs has better electrical,mechanical and adhesive properties than the other two composites. |
