In the present paper, we reported the fabrication of a highly hydrophilic nanometer-scale modified surface on a poly(ether ether ketone) (PEEK) substrate by photoinduced graft polymerization of 2-methacryloyloxyethyl phosphorylcholine (MPC) in the absence of photoinitiators. Photoirradiation results in the generation of semibenzopinacol-containing radicals of benzophenone units in the PEEK molecular structure, which acts as a photoinitiator during graft polymerization. The poly(MPC)-grafted PEEK surface fabricated by a novel and simple polymerization system exhibited unique characteristics such as high wettability and high antiprotein adsorption, which makes it highly suitable for medical applications.
在本文中，我们报道了一种通过在无光引发剂存在下光引发 2-（甲基丙烯酰氧）乙基磷酸胆碱（MPC）接枝聚合，在聚醚醚酮（PEEK）基底上制备高度亲水的纳米级改性表面的方法。光辐照导致 PEEK 分子结构中苯甲酮单元的半二苯甲酮含量自由基的生成，其在接枝聚合过程中充当光引发剂。通过新型简单聚合体系制备的接枝聚（MPC）-PEEK 表面表现出独特的特性，如高润湿性和高抗蛋白质吸附性，使其非常适合医疗应用。
