Description

technical field [0001] The invention relates to an experimental device capable of performing electrochemical reactions and studying electrode reaction kinetics under high temperature and high pressure conditions, especially an experimental device that can be used in supercritical CO 2 / Experimental device for electrochemical synthesis of conductive polymer thin films in homogeneous and multiphase systems with conductive solutions. Background technique [0002] Conductive polymer films (polypyrrole, etc.) have broad application prospects in high-tech value-added products such as fuel cells and biosensors. At present, the polymer conductive film is mainly prepared by electrochemical synthesis in aqueous solution or organic solvent, but this method mainly has problems such as environmental pollution and poor uniformity and density of the synthesized film, and the uniformity and density of the film is directly proportional to its conductivity. relation. It was found that the i...
