Silver films / coatings is a kind of new material with great potential in the field of high and new technology, and has been extensively used in modern industry in recent years.SThe silver thin films/coatings prepared by magnetron sputtering have excellent adhesion. The microstructure and properties adjustment of silver thin films/coatings can be achieved by selecting appropriate deposition parameters.SIn this paper, the main preparation methods of silver thin films/coatings deposited by magnetron sputtering are summarized the research progress of silver thin films/coatings in its main application fields is reviewed, and the future development of silver thin films is prospected.
