Abstract
An electrode and a method of making an electrode includes treating polymers that contain functional groups, which by surface functionalization, such as hydrolysis, ozone treatment or carbon-carbon double-bond oxidation to produce hydroxyl functional groups on the surface. Reacting methacryloyl chloride with the resulting hydroxyl functional groups thereby providing a reactive surface. Photopolymerizing or thermal polymerization of crosslinked acrylate or methacrylate polymers on the reactive surface to produce a membrane covalently bonded to the underlying substrate. In addition such an electrode can also be produced on a polystyrene substrate by reacting methacryloyl chloride with the polystyrene substrate and photopolymerizing or thermally polymerizing to produce crosslinked acrylate or methacrylate polymers on the reactive surface to produce a membrane covalently bonded to the underlying polystyrene substrate.
