Abstract

The invention relates to an underwater super-oleophobic polymer film, and in particular relates to a preparation method of the underwater super-oleophobic polymer film with a micro-nano-structured surface. According to the method, a transparent polymer film or a non-transparent polymer film sanded by abrasive paper is used as a template and in-situ polymerization one-time forming is carried out on the transparent polymer film or the non-transparent polymer film in a mixed solution of monomers containing polymers, thus obtaining the underwater super-oleophobic polymer film with the micro-nano-structured surface. The shape of the transparent polymer film template or the non-transparent polymer film template sanded by the abrasive paper is copied by the underwater super-oleophobicpolymer film, so that the underwater super-oleophobic polymer film has super oleophobicity underwater.

Description

technical field [0001] The invention relates to an underwater super-oleophobic polymer film, in particular to a preparation method of an underwater super-oleophobic polymer film with a micro-nano structure on the surface. Background technique [0002] Wettability is an important property of solid surfaces. Solids with underwater superoleophobic properties have attracted widespread attention due to their potential applications in crude oil transportation, marine antifouling, and marine oil pollution control. [0003] Surface energy substances modified on substrates with micro-nano composite structures are an important method for preparing superoleophobic materials. Such literature reports include a "super-oleophobic surface" reported by Tsujii et al. (Angew. Chem. Int. Ed. 1997, 36, 1011-1012). Xie, Q.D. et al. (Adv. Mater. 2004, 16, 302-305) reported "a method for constructing a super-amphiphobic surface with a biomimetic structure". Hu Jiwen et al. (patent CN 101824273A,...
