Conducting Poly (p-Xylylidenes).
Abstract
Poly(p-xylylidenes) having a high degree of polymerization in the form of films, foams or highly molecularly oriented films and fibers are chemically modified from insulators to conducting materials by exposure to either p- or n-type dopants. Poly (p-xylylidene) films are cast from aqueous solutions of a poly (p-xylene-a-dimethylsulfonium salt) polyelectrolyte. Processing of the films at elevated temperatures can yield both fibers and foams. Exposure of the poly(p-xylylidene) films, fibers or foams to p-type dopants result in an up to fifteen order of magnitude increase in conductivity, while n-type coping yields a nine order of magnitude increase. Doping of molecularly oriented films and fibers yields a highly anisotropic conductor with a greatly improved conductivity in the orientation direction. (Patent applications)
