Modification of surfaces for fluid and solid repellency

摘要

H:/rbr/Intrwovn/NRPortbl/DCC/RBR/l3187834_ .docx-16/02/2017 Articles, methods of making, and uses for modifying surfaces for liquid repellency are disclosed. The liquid repellant surfaces comprise a surface comprising an anchoring 5 layer. The anchoring layer, which forms an immobilized molecular anchoring layer on the surface, has a head group that is covalently linked to, or adsorbed onto, the surface and a functional group. The functional group of the treated surface has an affinity for a lubricating layer, which is applied to the treated surface. The anchoring layer and replenishable lubricating layer are held together by non-covalent attractive forces. 10 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.
