| 摘 要： | 金属纳米粒子由于其小的尺寸和大的比表面积等特点，使其具有独特的热性能、电性能、磁性能和光性能，以及很强的团聚趋势。因此金属纳米粒子是否被稳定在纳米尺度内，是它们能否表现出独特性能的关键。本文综述了非离子聚合物、聚电解质、两亲聚合物、双亲水聚合物、树状聚合物对金属纳米粒子的稳定作用及其稳定机理的研究进展。

| Abstract: | Metal nanoparticles exhibit unique thermal, electronic, magnetic and optical properties because of the small sizes, large specific surface characteristics and the aggregative trend. Whether metal nanoparticles can be stabilized in nano scale is the key for them to exhibit unique properties. The progress in stabilizations and stabilization mechanisms of the metal nanoparticles by nonionic polymers, polyelectrolytes, amphiphilic polymers, double-hydrophilic polymers, and dendrimers is reviewed. |
