A new “adsorption-cross-linking” technology is presented to generate a highly dense polymer brush coating on various nonpolar substrates, including the most inert and low-energy surfaces of poly(dimethylsiloxane) and poly(tetrafluoroethylene). This prospective surface modification strategy is based on a tailored bifunctional amphiphilic block copolymer with benzophenone units as the hydrophobic anchor/chemical cross-linker and terminal azide groups for in situ postmodification. The resulting polymer brushes exhibited long-term and ultralow protein adsorption and cell adhesion benefiting from the high density and high hydration ability of polyglycerol blocks. The presented antifouling brushes provided a highly stable and robust bioinert background for biospecific adsorption of desired proteins and bacteria after secondary modification with bioactive ligands, e.g., mannose for selective ConA and Escherichia coli binding.

通过吸附-交联策略在非极性表面上的高防污聚合物刷涂料

提出了一种新的“吸附交联”技术，可以在各种非极性基材上形成高密度的聚合物刷涂，包括非活性和低能量的聚（二甲基硅氧烷）和聚（四氟乙烯）表面。这种预期的表面改性策略是基于量身定制的双功能两亲嵌段共聚物，其中二苯甲酮单元作为疏水性锚/化学交联剂和末端叠氮化物基团，用于原位后改性。得益于聚甘油嵌段的高密度和高水合能力，所得聚合物刷表现出长期且超低的蛋白质吸附和细胞粘附性。大肠杆菌结合。
