作为一种控制纳米线和纳米管表面性质的方法，我们提出了一种从硅/二氧化硅核/壳纳米线表面生长聚合物的方法。在用聚合物引发剂对纳米线表面进行改性后，采用原子转移自由基聚合(ATRP)从纳米线表面生长出甲基丙烯酸酯高分子链。用扫描电子显微镜、透射电子显微镜和电子能谱对产物结构进行了表征。在刻蚀硅芯之后，得到的聚合物涂层纳米管将具有亲水的二氧化硅内核和疏水聚合物外壳。
As a way to control the surface properties of nanowires and nanotubes, we present a method for growing polymer from the surface of silicon/silica core/shell nanowires. After modification of nanowire surfaces with polymer initiators, Atom Transfer Radical Polymerization (ATRP) was used to grow methacrylate polymer chains from the surface. The resulting structures were characterized by SEM, TEM, and EELS. After etching the silicon cores, the resulting polymer-coated nanotubes will have hydrophilic silica cores with hydrophobic polymer shells.
