The preparation of hybrid nanocomposite materials derived from polyhedral oligomeric silsesquioxane (POSS) nanoparticles and polyimide (PI) has recently attracted much attention from both academia and industry, because such materials can display low water absorption, high thermal stability, good mechanical characteristics, low dielectric constant, flame retardance, chemical resistance, thermo-redox stability, surface hydrophobicity, and excellent electrical properties. Herein, we discussed the various methods that have been used to insert POSS nanoparticles into PI matrices, through covalent chemical bonding and physical blending, as well as the influence of the POSS units on the physical properties of the PIs.

由多面体低聚倍半硅氧烷（POSS）纳米粒子和聚酰亚胺（PI）衍生的杂化纳米复合材料的制备最近引起了学术界和工业界的广泛关注，因为这类材料具有低吸水性、高热稳定性、良好的机械性能、低介电常数、阻燃性、耐化学性、热氧化稳定性、表面疏水性和优异的电学性能。在此，我们讨论了通过共价化学键合和物理共混将POSS纳米粒子引入PI基体的各种方法，以及POSS单元对PI物理性能的影响。
