摘要:
利用多巴胺在碱性醇/水体系中的氧化自聚反应制备得到粒径均一的聚多巴胺纳米微球(polydopamine spheres, PDS)，并进一步利用PDS结构中儿茶酚胺的还原性，原位还原硝酸银负载银纳米粒子，建立了银纳米粒子/聚多巴胺微球(Ag nanoparticles loaded PDS, AgNPs/PDS)的简单制备方法。利用紫外可见光谱、傅里叶变换红外光谱、扫描电子显微镜、X射线光电子能谱和电化学溶出伏安法对PDS及AgNPs/PDS的形貌、结构及成分进行分析。在最优条件下，粒径约为40 nm的球形AgNPs均匀固载在平均粒径约为200 nm的PDS表面。通过紫外可见吸收光谱现场监测了AgNPs/PDS对硼氢化钠还原 4硝基苯酚(4nitrophenol，4NP)的催化作用，结果表明AgNPs/PDS极大地加速了4NP的还原反应。这种绿色、简单、快捷的复合材料制备方法有望为新型功能材料构建提供新途径。
