目的 多面体低聚倍半硅氧烷(POSS)/聚合物复合材料是近年来材料科学领域研究的热点。把具有特殊笼型结构的新型有机-无机纳米粒子POSS用于改性有机玻璃(PMMA)，可以提高PMMA的热学、力学和阻燃等性能，从而提升PMMA的使用效能，拓宽其应用领域。方法 通过对文献进行分析，阐明POSS的合成方法、特性和应用，并全面综述POSS改性PMMA的应用研究进展。结论 分析了目前POSS改性PMMA相关研究的不足，并提出了POSS改性PMMA拓展代替钢化玻璃应用于高层建筑和传统透明材料应用包装领域拟解决的关键问题。

Polyhedral oligomeric silsesquioxane (POSS)/polymer composites have been a hot topic in the field of materials science in recent years. The new organic-inorganic nanoparticle POSS with special cage structure can be used to modify the organic glass (PMMA), which can improve the thermal, mechanical, and flame retardant properties of PMMA, so as to improve the use efficiency of PMMA and broaden its application field. The literature analysis was carried out to clarify the synthesis methods, characteristics, and applications of POSS. And the application of POSS modified PMMA was comprehensively reviewed. This paper analyzes shortcomings of the current research on POSS modified PMMA, and puts forward the key problems to be solved on how to replace tempered glass with POSS modified PMMA in the field of high-rise buildings and traditional transparent material packaging.
