Polymer matrix electrodes

A method for preparing a polymeric matrix electrode comprising:

• adding to a polymeric matrix in liquid form a metallic and/or non-metallic electrical conductive material to obtain a mixture, wherein
• the polymeric matrix is selected from the group consisting of:
• acrylonitrile-butadiene-styrene copolymer, ethylene-vinyl acetate, polyacetal, polyamide 6, polyamide 12, polyamide 66, polyamide, polybutylene terephthalate, polycarbonate, polyetherketone, polyetheretherketone, polyether sulphone, polyethylene, low-density polyethylene, high-density polyethylene, polyphenylene sulfide, poly(phenylene oxide), polyoxymethylene, polypropylene, polyvinylidene fluoride, and any of their combinations;
• the metallic and/or non-metallic electrical conductive material is selected from the group consisting of:
• carbon;
• carbon nanotubes;
• carbon nano-horn;
• carbon black;
• graphene;
• fullerene;
• silver;
• copper;
• gold;
• aluminum;
• zinc;
• chromium;
• tin;
• iridium;
• tungsten;
• nickel;
• iron;
• platinum;
• lead;
• aluminum-tin oxide (AZO);
• and indium-tin oxide (ITO);
• and conductive ceramics;
• wherein said metallic and/or non-metallic electrical conductive material added at a dose 0.1-40% to the polymeric matrix;
• wherein:
• the carbon is in the form of carbon fiber, carbon nano-fiber, carbon nanotubes, carbon black, carbon nano-clays or carbon nano-horn,
• the graphene is in the form of graphene oxide, graphene, nano platelets or fullerene,
• the metallic electric conductive material is in the form of powder, dispersion, gel, particles, microparticles or nanoparticles and/or nanowire,
• the conductive ceramics are in the form of powder, dispersion, gel, particles, microparticles or nanoparticles and/or nanowire;
• maintaining the mixture so obtained under stirring, for a time period of 1-120 minutes, and
• putting the stirred mixture into a mold, and after molding, a polymeric matrix electrode is prepared by machining.
