Preparation method of super-amphiphobic silicon carbide film with self-cleaning function
The invention discloses a preparation method of a super-amphiphobic silicon carbide film with a self-cleaning function, which comprises the following steps: a) carrying out oxidation treatment on a silicon carbide film to obtain an oxidized silicon carbide film; b) mixing nano-particles and micro-particles with different particle sizes to obtain micro-nano blended particles, and then adding the micro-nano blended particles and a silane coupling agent into ethanol to obtain a suspension; c) adding a fluorine-containing low-surface-energy substance into ethanol to obtain an impregnation liquid; d) spraying the suspension on the surface of the oxidized silicon carbide film, and thermally curing at 55-65 DEG C for 15-45 minutes to obtain a modified silicon carbide film; and e) impregnating the modified silicon carbide film in the impregnation liquid for grafting modification, taking out the modified silicon carbide film, and thermally curing the modified silicon carbide film at 55-65 DEG C for 15-45 minutes to obtain the super-amphiphobic silicon carbide film. The preparation method is simple, reaction conditions are mild, and the prepared super-amphiphobic silicon carbide film has a self-cleaning function and good chemical stability.
