Abstract
The invention belongs to the technical field of super-hydrophobic coatings, and particularly relates to a self-cleaning antifouling coating for a solar cell panel and a preparation method of the self-cleaning antifouling coating. The self-cleaning antifouling coating for the solar cell panel is mainly composed of polydimethylsiloxane, modified molybdenum disulfide, a curing agent and other raw materials. The prepared self-cleaning antifouling coating for the solar cell panel has the super-hydrophobic characteristic, the maximum contact angle CA can reach 161 degrees, and the self-cleaning antifouling coating has extremely low surface energy and shows excellent self-cleaning and antifouling effects. Meanwhile, the self-cleaning antifouling coating still has a super-hydrophobic characteristic after being abraded by abrasive paper, and has excellent mechanical durability; a corrosion resistance test shows that the coating also has excellent corrosion resistance, and an ideal self-cleaning antifouling coating is provided for removing dust and dirt on the surface of photovoltaic devices such as a solar cell panel.
