  • Patent number: 11118063
    Abstract: The present invention discloses a durable super-hydrophobic manganese dioxide coating and a preparation method thereof, belonging to the field of metallic material surface treatment. In the method, by using manganese sulfate as a raw material, based on the property of interface reaction, a manganese dioxide coating is synthesized on the metallic material surface by simple and convenient solution impregnation, and then processed by hydrophobization with stearic acid to obtain a super-hydrophobic manganese dioxide coating. This coating has excellent chemical stability to organic solvents such as n-hexane, isooctane, dodecane, tetradecane, and acids, alkali and salt solutions at different pH values, and exhibits great resistance against dynamic water shear and good durability, with broad application prospect.
