最近，从学术和工业的角度来看，基于多面体低聚倍半硅氧烷（POSS）的杂化聚合物引起了人们的广泛兴趣。 POSS 是完全定义的纳米级尺寸分子，可以用适合合成新有机-无机杂化物的反应基团进行功能化，从而为设计和构建具有纳米相行为的极其明确尺寸的材料提供了机会。 POSS 已通过共聚、接枝或共混成功地融入普通聚合物中。人们已经制备了多种含 POSS 的共聚物，它们在开发各种具有不同性能的杂化纳米材料方面表现出了巨大的潜力。这项工作批判性地评估了 POSS 聚合物材料合成以及 POSS 纳米复合材料的最新进展。详细描述了 POSS 笼、含 POSS 笼的单体、POSS 树枝状聚合物核、含 POSS 的聚合物（纳米砌块）和 POSS 纳米复合材料的合成。这项工作还评估了 POSS 纳米砌块的特性，这些砌块可用于开发纳米复合材料。这些性能包括机械性能、热性能、阻燃性能和粘弹性性能。对 POSS 纳米砌块的结构、形态和相容性的研究进行了综述。涵盖的其他特性包括离子迁移率和膨胀特性以及 POSS 纳米砌块的孔隙率。最后，强调了现有的和未来可能的应用并得出了最终结论。
Polyhedral oligosilsesquioxane (POSS)-based hybrid polymers have generated much interest recently, both from the academic and industrial points of view. POSS are completely defined molecules of nanoscale dimensions that may be functionalized with reactive groups suitable for the synthesis of new organic–inorganic hybrids, thus providing the opportunity to design and build materials with extremely well-defined dimensions possessing nanophase behavior. POSS have been successfully incorporated into common polymers via copolymerization, grafting or blending. A variety of POSS-containing copolymers have been prepared and they have displayed great potential in the development of a wide range of hybrid nanomaterials with diverse properties. This work has critically evaluated the recent developments in syntheses of POSS polymer materials leading to POSS nanocomposites. The syntheses of POSS cages, monomers containing POSS cages, POSS-dendrimers' cores, POSS-containing polymers (nanobuilding blocks) and POSS nanocomposites are described in detail. This work also assesses the properties of POSS nanobuilding blocks that can be otherwise used for developing nanocomposites. Such properties include mechanical, thermal, flame-retardant and viscoelastic properties. Investigations into the structure, morphology and compatibility of POSS nanobuilding blocks have been reviewed. Other properties covered include the ion-mobility and swelling characteristics as well as porosity of POSS nanobuilding blocks. Lastly, existing and possible future applications are highlighted and final conclusions are drawn.
