Thin adherent adjustable conductivity polymer layer is produced on oxidic particles, e.g. for electrode materials, conductive pigments or additives, by adding monomer solution covered particles to an oxidizing agent solution

摘要

Ultra-thin, compact, adherent, adjustable electrical conductivity polymer layer production on oxidic particles, by adding monomer solution covered particles to an oxidizing agent solution, is new. Production of ultra-thin, compact, adherent polymer layers of adjustable electrical conductivity on oxidic particle surfaces comprises oxidative treatment of the particle surfaces directly with a solution of monomers, which form intrinsically conductive polymers, by mixing the particles with the monomer solution and then adding to a separate solution comprising the oxidizing agent. An Independent claim is also included for oxidic particles having ultra-thin, compact, adherent polymer layers of adjustable electrical conductivity formed directly on their surfaces by the above process.
