摘要(Abstract)：

采用自由基聚合制备了一种双亲性丙烯酸酯无规共聚物PDHES。以氯金酸为前驱体，通过原位还原制备得到金纳米颗粒(Au NPs)，并将其负载在PDHES分子链上；通过溶剂诱导方法使负载Au NPs的PDHES自组装形成Au@PDHES复合纳米粒子。探究了氯金酸浓度对Au NPs形成过程及Au@PDHES复合纳米粒子形貌的影响，考察了Au@PDHES对4–硝基苯酚还原反应的催化性能。进一步以Au@PDHES作为颗粒乳化剂稳定油水界面，研究了油水体积比对乳化性能的影响。结果表明：PDHES可将氯金酸前驱体原位还原为Au NPs；自组装形成的Au@PDHES复合纳米粒子呈球形，其平均粒径约为160 nm，Au NPs均匀分布在复合纳米粒子上，该复合纳米粒子对4–硝基苯酚具有良好的催化性能，同时能够形成稳定的水包油型乳液，有望用于油水界面催化及微反应器。
