Abstract: A method for preparing a transparent fluorine-free, super-lubricating and oil-proof coating includes: dissolving a sulfhydryl compound, a styrene copolymer, a low surface energy component, and a photoinitiator in an organic solvent, conducting a uniform stirring to obtain a mixture, coating the mixture onto a substrate, and conducting a curing under an ultraviolet lamp to obtain the transparent fluorine-free, super-lubricating and oil-proof coating. The coating has excellent adhesion resistance to various organic solvents with low surface tension and even liquids with high viscosity, and has excellent chemical stability and mechanical durability. The coating can be applied to various substrates such as glass, an aluminum sheet, a steel sheet, and a polymer without limitations of a use environment, maintains excellent adhesion resistance in the environment of air, oil, and water, and has wide applicability. Moreover, according to the method, various ways such as spraying, dip-coating and spin-coating can be used.
