The Development Of Conductive Composite Surfaces By A Diffusion-Limited In Situ Polymerization Of Pyrrole In Sulfonated Polystyrene Ionomers, M. Cristina De Jesus, Robert Weiss, Yuping Chen
Robert Weiss
Electrically conductive composite surfaces were prepared by a diffusion-controlled in situ polymerization of pyrrole in the surface layer of sulfonated polystyrene ionomer films. Premolded films of the ionomer sulfonic acid derivatives were sequentially immersed in aqueous solutions of pyrrole and FeCl3, and polymerization occurred only where both the monomer and the oxidant were present. The penetration of the polypyrrole (PPy) into the film was controlled by varying the immersion time in the monomer solution. The amount of PPy produced depended on the immersion time of the film in the monomer and the degree of sulfonation of the ionomer. Surface conductivities …

Highly conductive polyaniline/sulfonated polystyrene (PANI/HSPS) composites were synthesized by in situ polymerization of aniline within HSPS matrixes. The amount of polyaniline, the conductivity and the morphology of the composite films depend on the sulfonation level of HSPS and the immersion time in the aniline solution. A maximum conductivity of 0.1 S/cm and high transmittance of 80% (at 460–680 nm) have been achieved.
