Phytic acid (PA), which is a natural and innoxious plant constituent, can strongly adsorb on the metal surface because of its six phosphate groups. In this work, based on the chelating properties of PA and the reaction between PA and hydrolyzable vinyltriethoxysilane (VTES), we developed a novel and facial strategy to generate hierarchical-layer nanospheres on the metal mesh surface and fabricated robust superhydrophobic and superoleophilic miniature metal mesh ships. Because of their superwetting properties, the modified meshes could easily remove and recycle the oil spills from the water surface (>90% collection efficiency), and have high oil/water separation capacity (>96%). The excellent stability, corrosion resistance, and robust mechanical durability endow the modified mesh ships with more advantages in a marine environment. We envision that these superhydrophobic meshes modified with PA and VTES are sustainable, environmentally friendly, and easy to scale up and hence display great potential in practical application.
植酸(PA)是一种天然无毒的植物成分,由于其具有六个磷酸基团,因此可以强烈吸附在金属表面上。在这项工作中,基于 PA 的螯合特性以及 PA 与可水解的乙烯基三乙氧基硅烷(VTES)之间的反应,我们开发了一种在金属网表面上生成分层纳米球的新颖且简便的策略,并制造了坚固的超疏水超亲油微型金属网船。由于其超润湿特性,改性网可以轻松地从水面上清除和回收溢油(>90%的收集效率),并且具有很高的油/水分离能力(>96%)。出色的稳定性,耐腐蚀性和坚固的机械耐用性使改性网船在海洋环境中具有更多优势。我们设想,这些经过 PA 和 VTES 改性的超疏水网具有可持续性,环保且易于规模化,因此在实际应用中具有很大的潜力。
