半缩合低聚硅氧烷的合成及应用进展

摘要

The types and preparation methods of incompletely condensed silsesquioxanes (POSS)are in-troduced. Then the advantages and disadvantages of different POSS are analyzed. Moreover,the latest re-search progress on the incompletely condensed POSS modified materials (including modified epoxy,acrylic, silicone,polyurethane resin,etc. )is described. Finally,the development and application prospect of the in-completely condensed POSS are also dsicussed.%介绍了半缩合低聚硅氧烷（简称半缩合POSS）的类别，阐述了半缩合POSS的制备方法与途径，分析了各自的优缺点，并对半缩合POSS改性材料（包括改性环氧树脂、丙烯酸树脂、有机硅、聚氨酯等）的最新研究进展进行了描述，指出了半缩合POSS的发展与应用前景。
