Abstract

The invention discloses a method for preparing a conductive high molecular material coated metal-based inert electrode material. The method comprises the following three steps: (1) preparing a metal framework substrate; (2) preparing a conductive high molecular coating material; and (3) coating the conductive high molecular coating material on the metal framework substrate. The prepared conductive high molecular material coated metal-based inert electrode material can obviously improve the electrocatalytic activity of a plate electrode and the corrosion resistance of a polar plate and is particularly suitable for a chloride system or a sulfate system containing high chloride ion content; and the composite material can be used for inert anodes, battery electrodes, sensor devices, capacitor electrodes and the like in the wet metallurgical extraction process of nonferrous metals, and the energy consumption can be obviously reduced in the electrodeposition process of the nonferrous metals.

Description

technical field [0001] The invention relates to a preparation method of a metal-based inert electrode material coated with a conductive polymer material, which is mainly used in an electrochemical process. Background technique [0002] Conductive polymer materials (polyaniline, polypyrrole, polythiophene) have become one of the fastest-growing functional materials due to their good chemical stability, electrochemical reversibility, and excellent metal anti-corrosion properties. Based on conductive polymer materials, many new technologies are currently being developed, such as sensor elements, electrode materials, all-plastic metal anti-corrosion technology, ship anti-fouling technology, solar cells, electromagnetic shielding technology, anti-static technology, electrochromism and stealth technology etc. However, the conductive polymer materials obtained by chemical oxidation or electrochemical oxidation are all powders, which are difficult to form and process, and their ele...
