Abstract

The invention provides a method for preparing an anti-aging super-hydrophilic surface, which comprises the following steps of: putting a substrate with a super-hydrophobic film formed on the surface of the substrate into heating equipment, heating to 560 DEG C or above, keeping for a period of time, cooling and taking out to obtain the anti-aging super-hydrophilic surface on the substrate. The ceramic surface is wetted and modified, and the process is simple, energy-saving, environment-friendly, safe and efficient. The hydrophilic surface is prepared by adopting a two-step method of atmospheric pressure low-temperature plasma polymerization and heating, the range of applicable materials is wide, the idea is novel, and the method has generalizability. And the conversion from the super-hydrophobic film to the super-hydrophilic film is realized by accurately controlling the process condition parameters of the two procedures.
