Antifouling surfaces are important in a broad range of applications. An effective approach to antifouling surfaces is to covalently attach antifouling polymer brushes. This work reports the synthesis of a new class of antifouling polymer brushes based on highly hydrophilic sulfoxide polymers by surface-initiated photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization. The sulfoxide polymer brushes are able to effectively reduce nonspecific adsorption of proteins and cells, demonstrating remarkable antifouling properties. Given the outstanding antifouling behavior of the sulfoxide polymers and versatility of surface-initiated PET-RAFT technology, this work presents a useful and general approach to engineering various material surfaces with antifouling properties, for potential biomedical applications in areas such as tissue engineering, medical implants, and regenerative medicine.

通过高度亲水的亚砜聚合物刷的表面接枝实现防污表面

防污表面在广泛的应用中很重要。防污表面的有效方法是共价连接防污聚合物刷。这项工作报告了通过表面引发的光诱导电子/能量转移-可逆加成-断裂链转移（PET-RAFT）聚合合成基于高亲水性亚砜聚合物的新型防污聚合物刷。亚砜聚合物刷能够有效减少蛋白质和细胞的非特异性吸附，显示出卓越的防污性能。鉴于亚砜聚合物具有出色的防污性能以及表面引发的PET-RAFT技术的多功能性，这项工作提出了一种有用且通用的方法来设计具有防污性能的各种材料表面，
