Description

Technical field

[0001] The invention relates to a preparation method of a wear-resistant super-hydrophilic underwater super-oleophobic coating. Background technique

[0002] Super-hydrophilic surfaces have important applications in anti-fogging, self-cleaning, enhanced boiling heat transfer, and oil-water separation. In recent years, they have been widely synthesized and applied to different substrates. As far as most superhydrophilic surfaces are concerned, due to their strong affinity for water, they also show highly oleophobic or super oleophobic properties underwater. However, the traditional methods for preparing super-hydrophilic surfaces mostly use surface chemical modification or deposit hydrophilic materials with poor mechanical strength on the surface. For example, the article "A novel superhydrophilic and underwater superoleophobic hydrogel-coated mesh for oil / water separation" published on page 4270 of the 23rd issue of Advanced Materials in 2011 introduced a method ...
