摘要:

通过调控在铜网表面电镀铜的时间制备了一系列具有不同黏附性的水下超疏油铜网表面, 并进一步在铜网表面包覆一层磷酸二氢铝(ADP)纳米涂层. 在保持铜网表面原有微结构形貌不变的前提下, ADP纳米涂层有效增强了铜网表面微纳结构的机械强度及表面浸润特征的稳定性. 研究结果表明, 铜网表面不同微结构赋予了表面与油滴之间不同的接触状态, 从而产生了不同的黏附性; ADP包覆后铜网表面微结构机械强度的增加, 得益于包覆后表面微观结构在外力作用下最大应力和最大横向位移的明显降低.

Abstract:

A series of underwater superoleophobic copper meshes with tunable oil adhesion were fabricated by adjusting the time of eletrodeposition copper on copper mesh. Furthermore, after coating a layer of rigid aluminum dihydrogen phosphate(ADP) onto the as-prepared copper meshes, the mechanical stability of the microstructure on the copper meshes were effectively enhanced while maintaining the original microstructure morphology and oil adhesion property unchanged. The different oil adhesion of as-prepared copper meshes could be ascribed to the difference of surface microstructures that results in different solid/oil contact model in water. Theoretical simulations analysis reveals that the enhanced effect of surface microstructure results from the coating is due to the decreases the maximum transverse deformation and stress on the microstructure.
