| 摘 要： | 通过两步原子转移自由基聚合,制备了4种不同嵌段长度的四臂星型嵌段共聚物苯乙烯-聚4-乙烯基吡啶嵌段共聚物(PS-b-P4VP)4.在选择性溶剂甲苯中,随着嵌段长度的变化,自组装胶束的形态从球型到短棒状和纤维状的转变,其中(PS25-b-P4VP90)4自组装形成的以P4VP为核,以PS为花瓣型壳的纤维状胶束.以这种纤维状胶束作为模板,制备了金纳米粒子均匀分布的一维纳米材料

| Abstract: | The star-block copolymers poly(styrene)-block-poly(4-vinylpyridine)(PS-b-P4VP)_4 were synthesized by two-step atom transfer radical polymerization(ATRP)using pentaerythritol tetrakis 2-bromoisobutyrate as initiator.The structure and molecular weight of polymers was experimentally confirmed by 1-HNMR spectroscopy,gel permeation chromatography(GPC)and IR,respectively.The star-block copolymers formed fiberlike micelles in toluene with the P4VP core and the PS petal-like shell.The micellar size and morphology w... |
