Abstract
A method of producing electrically conductive plastics materials from polymers and electrically conductive particles wherein an aqueous dispersion of polyacrylate, such as a thermally cross-linkable copolymer based upon ethyl acrylate, or a polyisobutylene is mixed with an aqueous dispersion of electrically conductive particles such as noble metals, non-metallic materials coated with noble metals, or carbon, and the resulting mixture is spread out in a thin layer on a support, whereafter the water is evaporated at a temperature above the softening of the plastics material.

A method of producing a thermoplastically further processable, electrically conductive plastic material from polymers and electrically conductive particles, comprising the steps of (1) mixing an aqueous dispersion of a thermoplastic synthetic resin with an aqueous dispersion of the electrically conductive particles, (2) spreading out the resulting mixture in a thin layer on a substrate, (3) subsequently evaporating water from the mixture at a temperature above the softening point of the synthetic resin, and (4) subsequently removing the formed electrically conductive plastic material layer from the substrate.
