Articles, methods of making, and uses for modifying surfaces for liquid repellency are disclosed. The liquid repellant surfaces comprise a surface comprising an anchoring layer. The anchoring layer, which forms an immobilized molecular anchoring layer on the surface, has anchoring molecules, where each anchoring molecule has a head group that is covalently linked to the surface and a functional tail group. The anchoring molecules are crosslinked to each other to form a crosslinked network. The functional tail group has an affinity for a lubricating liquid, which is applied to the treated surface to form a lubricating layer. The anchoring layer and replenishable lubricating liquid are held together by non-covalent attractive forces. Together, these layers form an ultra-repellant slippery surface that repels certain immiscible liquids and prevents adsorption, coagulation, and surface fouling by components contained within.
本发明公开了用于改变表面斥液性的物品、制造方法和用途。憎液表面包括由锚定层组成的表面。锚定层在表面形成固定分子锚定层,具有锚定分子,其中每个锚定分子具有与表面共价连接的头部基团和功能性尾部基团。锚定分子相互交联,形成交联网络。功能性尾基对润滑液具有亲和力,润滑液涂抹在处理过的表面上形成润滑层。锚固层和可补充的润滑液体通过非共价吸引力固定在一起。这些层共同形成了一个超强排斥性的滑溜表面,可以排斥某些不相溶的液体,防止其中所含成分的吸附、凝结和表面污垢。
