油污水对生态环境、人类健康带来各项危害。基于仿生超疏水超亲油特性可以有效的分离油水混合物，但材料亲油特性不可避免的带来了严重的膜污染问题，极大程度上降低了分离通量和效率。因此，寻求简单有效的方法来构筑具有自清洁作用的油水分离材料，以实现油污水的有效分离十分必要。本项目拟以聚苯并噁嗪作为低表面能材料，结合添加微米/纳米无机粒子的方法来构建表面粗糙结构，并以此共混物来修饰多种过滤材料来构筑仿生超疏水超亲油表面。从分子层面探索所构筑的仿生超疏水超亲油表面的表面润湿特性与苯并噁嗪分子内相互作用力之间的潜在联系，并对构效关系进行模拟计算研究，为聚苯并噁嗪基仿生表面的构筑提供理论指导。同时，探究树脂与光敏无机物形成的复合物的双重自清洁机制，最终实现油水分离材料的可再生利用。

The growing quantities of oil-water mixture are posing environmental threats on ecosystem and human health. Biomimetic superhydrophobic and superoleophilic surface is efficient for oil-water separation, while it suffers fouling during separation since the surface is originally superoleophilic. The membrane fouling can cause severe flux decline and affect the quality of the products. Thus, extensive interest has been aroused in developing oil-water separation materials with self-cleaning performance. Herein, we propose to fabricate a superhydrophobic and superoleophilic surface based on polybenzoxazine (PBZ) and micro-/nanoparticles, which has photo-induced and biomimetic self-cleaning performance. Effects of benzoxazine molecular structure and the amount of micro-/nanoparticles on surface wettability of as-prepared surfaces will be investigated at molecular level, and the structure-surface property relationship will be simulated and computed, providing theoretical direction for PBZ-based biomimetic surfaces in future. Additionally, the dual self-cleaning mechanism of polybenzoxazine/inorganic particles-based surface will be studied, obtaining a reproducible biomimetic superhydrophobic and superoleophilic surface for oil-water separation.
