Problems solved by technology

[0004] The existing super-oleophobic materials are mainly made of materials with low surface energy, which are both super-oleophobic and super-hydrophobic, and are a surface that cannot be wetted by most liquids at all, because during the preparation process A large number of fluorine-containing materials with low surface energy are used in it. On the one hand, they are expensive, resulting in high cost of such super-oleophobic coatings. On the other hand, the toxic effects on the environment and organisms cannot be evaluated at present.
