Biofouling on surfaces of various materials has attracted considerable attention in biomedical and marine industries. Surface grafting based on covalent surface‐initiated polymerization offers a popular route to address this problem by providing diverse robust polymer coatings capable of preventing the biofouling in complex environments. However, the existing methods for synthesizing polymer coatings are complicated and rigorous, or require special catalysts, greatly limiting their practical applications. In this work, a radical‐cation‐based surface‐initiated polymerization protocol to graft the surface of darkened trans‐polyisoprene (TPI) rubber with a thermo‐responsive smart polymer, poly(N‐isopropylacrylamide) (PNIPAM), through a simple iodine doping process is reported. A series of characterizations were performed to provide adequate evidence to confirm the successful grafting. Combining the thermal sensitivity of PNIPAM with the photothermal conversion ability of the darkened rubber, efficient bacteria‐killing and antifouling capabilities were successfully achieved as a result of temperature‐controlled iodine release and switchable amphiphilicity of PNIPAM.

用于热防污涂料的光热橡胶上的自由基阳离子引发的表面聚合

在生物医学和海洋工业中，各种材料表面的生物污垢引起了相当大的关注。基于共价表面引发的聚合的表面接枝提供了一种广泛的途径来解决此问题，方法是提供多种坚固的聚合物涂层，能够防止复杂环境中的生物污染。然而，现有的合成聚合物涂层的方法复杂且严格，或者需要特殊的催化剂，极大地限制了它们的实际应用。在这项工作中，基于自由基阳离子的表面引发聚合方案将变暗的反式聚异戊二烯（TPI）橡胶表面与对温度敏感的智能聚合物聚（N报道了通过简单的碘掺杂过程得到的-异丙基丙烯酰胺）（PNIPAM）。进行了一系列表征，以提供足够的证据来证实成功的嫁接。将PNIPAM的热敏性与变黑橡胶的光热转化能力相结合，可实现温度控制的碘释放和PNIPAM的两亲性可转换，从而成功实现了高效的杀菌和防污能力。
