Description

technical field [0001] The invention relates to polymer composite coatings, in particular to a method for preparing high-efficiency nickel-graphite powder for preparing various EMI products and a special device thereof. Background technique [0002] With the development of society, especially the rapid development of various wireless communication technologies, electromagnetic radiation is ubiquitous, especially in large and medium-sized cities where people live concentratedly. Long-term exposure to high-frequency electromagnetic radiation will cause many adverse effects on human health. How to provide effective electromagnetic protection for related electronic equipment, ships, vehicles, buildings, etc. has become one of the most researched technical issues at present. [0003] Electromagnetic Interference (EMI for short) refers to the interference phenomenon caused by the interaction between electromagnetic waves and electronic components. There are two types of conducted ...
