Abstract Surface plasmon resonance can be used to manipulate light at the nanoscale. It was used here to trigger photopolymerization of an atom transfer radical polymerization (ATRP) molecular system, leading to a thin polymer shell at the surface of the metal nanostructure. The polymerization can be reactivated from the first polymer shell to covalently graft a second monomer layer with precise control over the thickness at the nanometric scale, depending on the photonic parameters. This route can be applied to different nanoobjects and allows an anisotropic surface modification in agreement with the spatial localization of the enhanced electromagnetic field near the nanostructure. This new route opens the door towards the preparation of multifunctional hybrid metal/polymer nanostructures.

等离子体触发的活性光聚合用于制备杂化聚合物/金属纳米粒子

摘要 表面等离子体共振可用于在纳米尺度上操纵光。它在这里用于触发原子转移自由基聚合 (ATRP) 分子系统的光聚合，从而在金属纳米结构的表面形成薄的聚合物壳。根据光子参数，可以从第一聚合物壳重新激活聚合以共价接枝第二单体层，并在纳米尺度上精确控制厚度。该路线可以应用于不同的纳米物体，并允许与纳米结构附近增强电磁场的空间定位一致的各向异性表面改性。这条新路线为制备多功能混合金属/聚合物纳米结构打开了大门。
