Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a coating with high antistatic performance and a preparation method thereof. Background technique [0002] In 2000, Professor Shirakawa of Japan and Professor MacDiarmid of the United States discovered that polyacetylene has high conductivity, which broke people's traditional thinking, that is, the concept that high molecular polymers are insulating, and made conductive polymers become the focus of many scientific research work. The focus of the researchers' research has aroused extensive attention. Conductive polymers are formed by chemical or electrochemical doping of polymers with conjugated π bonds, and a class of polymer materials whose conductivity extends from insulators to conductors. [0003] Traditional plastic parts are insulating materials, and home appliances are mostly made of plastic materials. Plastic materials have always been the main raw materials used in ho...
