✦ Synopsis

To prepare conducting polymer composites, porous polymethyl methacrylate (PMMA) particles with di †erent speciÐc surface areas were prepared by seeded emulsion polymerization and solvent extraction. The dried porous particles were imbibed with the oxidant solution and adsorbed pyrrole from a solution. The incorporation of pyrrole into the porous particles was achieved by chemical oxidative polymerization. The e †ects of various polymerization parameters on the electrical conductivity were systematically investigated. The important factors a †ecting conductivity were the porosity of the host polymer particles and the solvent polarizability.

This paper presents resistivity data for a range of surface-grafted and copolymerized polymers and some challenges yet to be faced in resolving the effects of surface modification on their surface properties, in particular on electrical resistivity in their surface regions. The principal substrates
