Substrate coating by conductive polymers through spontaneous oxidation and polymerization


A variety of substrates and substances were coated by conductive polymers at low temperature under ambient pressure. The substrate coating by heteroaromatic polymers proceeded through spontaneous oxidation and polymerization of the monomers, such as pyrrole (Py) and thiophene (Tp) derivatives. The monomer liquid, the solid nitrate oxidant, and the substrate were put in a closed vessel. The vapor of the activated monomer was spontaneously generated on the surface of the solid nitrate oxidant through diffusion of the monomer vapor. The monomer and its activated species were adsorbed and polymerized on the surface of any substrates in the reaction vessel. The thickness was controlled by the reaction time. The substituents of the monomers had an influence on the coating rate. The morphology of the coated polymers was changed by the substrates with the different wettability. The thin coating of the heteroaromatic polymer was applied to preparation of electrode for the charge storage based on the redox reaction. The thin coating on current collector showed the enhanced high-rate charge-discharge performance. The present synthetic approach can be applied to coating of polymer materials on a variety of substrates from the monomer vapor under mild conditions.
