Polypyrrole-polycarbonate blends

The Bjorklund works [169] lead us to develop a synthesis route in which the polypyrrole grows in the insulating matrix. Different solutions (PVC, polycarbonate, polyphenylene oxide,. ..) or emulsions (PTFE) of insulating polymer have been tested. In the case of PTFE-polypyrrole blend we used a classical oxidising coupling process by FeCl3 [104,127]. Comparative experiments have been performed on granular materials obtained by polypyrrole powder dispersion in an elastomer or an epoxyde resin [127]. [Pg.412]

Some measurements of this property have been made in a range of electrically conducting polymers. These include epoxy resin/polyaniline-dodecylbenzene sulfonic acid blends [38], polystyrene-black polyphenylene oxide copolymers [38], semiconductor-based polypyrroles [33], titanocene polyesters [40], boron-containing polyvinyl alcohol [41], copper-filled epoxy resin [42], polyethylidene dioxy thiophene-polystyrene sulfonate, polyvinyl chloride, polyethylene oxide [43], polycarbonate/acrylonitrile-butadiene-styrene composites [44], polyethylene oxide complexes with sodium lanthanum tetra-fluoride [45], chlorine-substituted polyaniline [46], polyvinyl pyrolidine-polyvinyl alcohol coupled with potassium bromate tetrafluoromethane sulfonamide [47], doped polystyrene block polyethylene [38, 39], polypyrrole [48], polyaniline-polyamide composites [49], and polydimethyl siloxane-polypyrrole composites [50].
