【摘要】：近年来,金属纳米粒子,尤其是金、银和铜,由于独特的热学、光学和电学性质及在纳米电子、纳米光学、信息存储、催化、生物和生物医学方面的潜在应用吸引了重大的研究兴趣。目前,聚合物包覆金属纳米复合粒子的研究得到广泛关注。一方面可以保持金属纳米粒子的特殊性质和功能,另一方面聚合物作为壳层材料可以增强纳米粒子的长期稳定性,调控纳米粒子的溶解性,提高纳米粒子与聚合物基体的相容性和可加工性等。本文综述了聚合物包覆金属纳米粒子的制备研究进展,主要包括乳液聚合法、沉淀聚合法、原位聚合法、配体交换法、壳交联法等,提出和分析了每种方法的优缺点,并对该材料的发展做了展望。聚合物包覆金属纳米粒子的工业化应用仍然是一个重要的挑战,有待进一步发展更适合工业化生产的方法。
[Abstract]:In recent years, metal nanoparticles, especially gold, silver and copper, have attracted great interest in research due to their unique thermal, optical and electrical properties and potential applications in nanoelectronics, nano optics, information storage, catalysis, biology and biomedicine. At present, the research of polymer coated metal nanocomposite particles has been widely concerned. On the one hand, the special properties and functions of metal nanoparticles can be maintained. On the other hand, polymers as shell materials can enhance the long-term stability of nanoparticles, control the solubility of nanoparticles, and improve the compatibility and processability of nanoparticles with polymer matrix. This paper summarizes the polymer coated metal nanoparticle preparation research progress, mainly including emulsion polymerization, precipitation polymerization, in-situ polymerization, ligand exchange, shell cross-linking method, proposed and analyzed the advantages and disadvantages of each method, and the development of the material is prospected. The industrial application of polymer coated metal nanoparticles is still an important challenge. It needs to further develop a more suitable method for industrial production.
