Fluoride-free self-cleaning coating as well as preparation method and application thereof

The invention discloses a fluoride-free self-cleaning coating as well as a preparation method and application thereof. The super-hydrophobicity of the coating disclosed by the invention is synergistically generated by a graphene wrinkle structure, a microstructure of nano-scale silicon dioxide and chemical modification of chlorosilane. The preparation method of the super-hydrophobic self-cleaning coating has the advantages of being environmentally friendly, simple in process, low in cost, wide in applicability and the like, and is suitable for industrial production. The coating provided by the invention has self-cleaning, antistatic, anticorrosive and antibacterial functions, and has wide application prospects in the fields of aviation, electric power, energy and the like. 本发明公开一种无氟自清洁涂层及其制备方法和应用。本发明的涂层的超疏水性是由石墨烯褶皱结构、纳米级二氧化硅的微观结构和氯硅烷的化学改性协同产生的。本发明的超疏水自清洁涂层的制备方法具有绿色环保、工艺简单、成本低、适用性广等特点，适合于工业化生产。本发明提供的涂层兼具自清洁、抗静电、防腐、以及抗菌功能，在航空、电力、能源等领域有着广阔的应用前景。
