doi:10.16085/j.issn.1000-6613.2017.04.023

Abstract

Abstract: Polyhedral oligomeric silsesquioxane(POSS) is a kind of nanoscale compound with cage-like organic-inorganic hybrid structure,with many unique physical and chemical properties. Functionalized POSS javascript:void(0);can be used in the synthesis and modification of silicone materials to improve their physical and chemical properties,and broaden their applications. In this paper,the synthesis methods of POSS were reviewed,with the emphasis on the functionalized POSS,including octaphenyl-POSS,octavinyl-POSS,octahydro-POSS,epoxy-POSS,amino-POSS,isocyanate-POSS and mono-functionalized POSS. In addition,the application progress of functionalized POSS in silicone was summarized from aspects of both physical and chemical modification. POSS has shown great potential in the field of polymer modification,and the application trend of functionalized POSS in silicone materials was also prospected. In the future,with the appearance of new POSS compounds,the application of functionalized POSS in silicone materials would achieve greater progress.

摘要： 笼型低聚倍半硅氧烷（POSS）是一种新型纳米有机-无机杂化材料，具有独特的物理化学性质。将官能化POSS用于有机硅材料的制备与改性，能够显著改善有机硅材料的物理化学性能，拓宽其应用领域。本文首先总结了POSS的制备方法，重点对聚合物改性中常用的官能化POSS的制备进行了综述，包括：八苯基POSS、八乙烯基POSS、八氢基POSS、环氧基POSS、氨基POSS、异氰酸酯基POSS和单官能化POSS。然后从物理改性与化学改性两方面总结了官能化POSS在有机硅材料中的应用进展。最后对官能化POSS在制备及应用领域的发展方向进行了展望。目前，POSS已经在聚合物改性领域展现出巨大的潜力，随着新型POSS化合物的出现，官能化POSS在有机硅材料领域的应用将取得更大的进展。
