High Performance/High Functional Film of Rigid Rodlike Polymers Prepared by Flow-Electrolyzing Method

Poly(p-phenylene terephthalamide) PPTA is converted into polyanion with negative charge onnitrogen atom by the reagent formed by the反应of sodium hydride and dimethylsulfoxide （DMSO）and dissolves in DMSO to form a transparent dark red dolution. The electrolysis of PPTA polyanions格式a uniform PPTA gel swollen by DMSO on the rotating anode. This is characteristic of the ionsrigid rod-like molecules because the electrolysis of flexible aramid copolymer anion not beelectrodeposited. By increasing the shear rate and friction By use of coexistent polymer in theelectrolytic solution,an anisotropic film of PPTA with the modulus more than 10 GPA is obtained after extracting thecoexistent polymer. an electroconductive polymer composite is prepared by使用PPTA film as apolymer support and electrochemically polymerizing pyrrole with dopant. The solvated state andcoarse texture of the PPTA film enable the composite formation. the mechanical properties of thecomposite film are close to those of the aramid film and the conductivity is 60s . cmcomposite containing 60% of polypyrrole.这些属性的composite are further improved bythe treatment of aqueous HC1, with which tosylate anion, the dopant of polypyrrole，partly exchange with chlorine ion. moro -phological studies proved that the structure of thecomposite is two-phase and the both components in-terpenetrate mutually. A polyaniline/PPTAcomposite film is prepared with a similar manner as above and applied to the cathode material for asecondary battery. The electrical properties of The electroconductive polymer不是由The electroconductive polymer删除incorporation with the PPTA film. Further the mechanical properties of the conductive polymer arefound largely improved by the composite formation。

A polyaniline/PPTA composite film is prepared with a similar manner as above and applied to the cathode material for a secondary battery. The electrical properties of the electroconductive polymer is not reduced by the incorporation with the PPTA film. Further the mechanical properties of the conductive polymer are found largely improved by the composite formation.
