Abstract: In order to deeply understand the preparation and properties of electromagnetic shielding conductive coatings and promote the large-scale production of high-efficiency and low-cost coatings, this paper first introduces the conductive mechanism of coatings and the basic principles of electromagnetic shielding. Secondly, focusing on different types of conductive fillers and resin matrices that constitute coatings, the effects of various materials on the overall performance of coatings due to differences in structure and properties are systematically introduced. The current research progress and multi-functional improvement for practical applications are reviewed. Finally, the problems of electromagnetic shielding coatings in filler structure, filler synthesis, compatibility of polymer matrix and filler are summarized and the prospect of future industrial development is expressed.
