摘要
通过可逆加成断裂链转移聚合(RAFT)成功制备了聚苯乙烯-聚4-乙烯基吡啶(PS-b-P4VP)双亲性嵌段共聚物。利用核磁共振氢谱(1 H NMR)对产物的结构进行了表征。然后研究了聚合物在选择性溶剂中的自组装行为,测试表明该聚合物在一定条件下可自组装形成囊泡状,以此结构作为原位反应器成功包覆纳米银制备了亚微米级的纳米复合材料,应用紫外-可见吸收光谱(UV-Vis)、X射线衍射(XRD)、扫描电镜(SEM)和X射线能谱仪(EDS)等测试手段对复合结果进行了表征。
Polystyrene-block-poly（4-vinylpyridine）（PS-b-P4VP） was synthesized by reversible addition-fragmentation chain transfer（RAFT） polymerization.The amphiphilic block copolymer,polystyrene-block-poly（4-vinylpyridine）（PS-b-P4VP） was evidenced by the means of 1H NMR.This amphiphilic block copolymer was then dissolved in the toluene,which is a selective solvent for PS and P4VP respectively.And then the self-assembly behavior was studied.Some testes show that the polymer in certain conditions can self-assemble into vesicle-like structures,which as an in-situ reactor successful preparation of nanosized silver composite materials.The result was characterized by UV-Vis spectra,X-ray diffraction（XRD）,scanning electron microscopy（SEM） and energy dispersive spectrometer（EDS）.
