| 摘 要： | 利用SiO2引发剂通过表面原子转移自由基聚合(SI-ATRP)的方法,合成了SiO2-grafted PSStNa的纳米复合材料。该纳米复合材料不仅具有核壳结构,而且是表面富集大量负电荷的"聚电解质刷"。并用X-射线光电子能谱(XPS)、透射电镜(TEM)和热分析(TGA)等对其进行了表征。

| Abstract: | We described the surface-initiated atom transfer radical polymerization(SI-ATRP) of sodium 4-styrenesulfonate using silica particle bromo-propionyl as macroinitiator to synthesize polymer nanocomposites of core-shell structure. They have the strong charge controlled "spherical polyelectrolyte brush", a negatively charged polyelectrolyte. These new organic inorganic hybrid particles have been extensively characterized by XPS(X-ray Photoelectron Spectroscopy), TEM (Transmission Electron Microscopy), and TGA(Thermo Gravimetric Analysis). |
