Background technique

[0002] The solar backsheet is located on the back of the solar panel. Fluorocarbon coatings made of PVDF, CTFE, and PTFE resins developed and produced by fluororesin multinational companies (such as Japan's Asahi Glass, Daikin, and France's Arkema, etc.) are widely used in It is used in the surface protection of bridges, buildings, railways, and communication facilities, and has withstood the harsh outdoor test for more than 40 years, showing excellent weather resistance. At the same time, material surface modification technologies including low-temperature plasma modification technology, radiation modification technology, and vacuum plasma chemical grafting technology are relatively mature. Therefore, fluorocarbon coatings, PET ...
