Abstract: The invention relates to an electro-chemical sensor and coating method, production method and corresponding uses. The coating method of an electro-chemical sensor comprises the following steps: coating a carbon-rich substrate, with a carbon content greater than or equal to 0 wt. % in relation to the total weight of the substrate, and with an organic polymer; and applying a cold plasma treatment to said coating. This method permits the production of electro-chemical sensors with a carbon-rich substrate, with a carbon content greater or equal to 50 wt. % in relation to the total weight of the substrate, and a modified organic polymer coating. These new sensors are suitable for the detection of, inter alia, dopamine, glucose, uric acid and ascorbic acid.

Abstract: The present invention relates to poly[2,2?-(3-alkyl-acetate)thiophene] polythiophenes of linear C1-C12 alkyls of formula (I) which are easily dispersible in alkyd and epoxy type paints, and the addition of 1% of the electroconductive polymer allows the use thereof as anti-corrosive additives and as anti-corrosion microparticles of regulatable properties. The addition of 1% of electroconductive poly[2,2?-(3-methylacetate)thiophene] (PTE) polymer in the alkyd and epoxy priming paint substantially improves the adherence, blistering and resistance to corrosion properties of steel, especially in marine and industrial environments, even with performances better than other polyaniline-based conductive polymers. The substitution of zinc and its derivatives with the electroconductive poly[2,2?-(3-alkyl-acetate)thiophene] (PTE) polymers in anti-corrosive epoxy and alkyd priming paints is technologically viable and, as a consequence, reduces the aggressive effect caused by these transition metals on the environment.
