【摘要】 介绍了两亲聚合物的结构特点及其在稳定金属胶体方面的应用情况。两亲聚合物作为保护聚合物所制备的金属—聚合物胶体体系性质稳定、粒径分布窄,特别适合于用作催化剂。对两亲聚合物在制备纳米金属催化剂体系方面的优势与不足和影响体系活性的主要因素也进行了综述。更多还原

【Abstract】 Amphiphilic copolymers have been paid much attention in recent years.Their structural features and applications in stabilizing metal colloids is reviewed in this paper.The metal—polymer colloidal systems protected by amphiphilic copolymers are very stable and have narrow size distribution.These systems are very fit for use as cat- alysts.The advantages and disadvantages of amphiphilic copolymers in preparing nanometallic catalysts and the main factors influencing activities of the catalysts are also reviewed.更多还原
