笼形倍半硅氧烷(POSS)是基于化学键合作用而形成的分子内杂化体系,这种有着规整立体结构同时具有单纳米尺度的有机无机杂化分子引起了研究人员的广泛关注,独特的纳米笼形结构也为分子水平上改进高分子的科学研究提供了可能性。本文综述了多面体倍半硅氧烷(POSS)的结构、性能与合成方法,重点介绍了巯基POSS、金属杂化POSS、含氟POSS以及含卤代烷的POSS这四类新型官能团POSS,展望了POSS在有机无机杂化材料领域方面的巨大应用前景,并对POSS基材料的发展趋势和有待于进一步解决的问题进行了探讨。
The cage silsesquioxane (POSS) is an intramolecular hybrid system based on the chemical bonding. This has a regular three-dimensional structure with a single nano-scale organic-inorganic hybrid molecules attracted widespread attention of researchers, a unique The nanocage structure also offers the possibility to improve the scientific research of polymers at the molecular level. In this paper, the structure, properties and synthesis methods of polyhedral silsesquioxanes (POSS) are reviewed. Four new POSS functional groups, POSS, POSS, POSS and Halogenated POSS are reviewed. POSS Organic and inorganic hybrid materials in the field of great application prospects, and the development trend of POSS-based materials and issues to be further explored.
