摘　　要：有机/无机杂化材料的改性及应用是目前材料科学中最富有活力的研究领域之一。其中,笼型倍半硅氧烷(Polyhedral oligomeric silsesquioxane,POSS)在分子水平上实现了有机组分与无机组分的结合,其结构呈硅氧骨架连接的立体笼型,具有优异的反应活性、耐热性、阻燃性、多孔性和纳米尺寸效应等特点,通过化学改性可将其应用在多个领域。该文主要从官能团改性、聚合改性和配位改性3个方面阐述了POSS的改性方法,综述了POSS在耐热材料、阻燃材料、增强材料和多孔材料等领域的应用研究进展,对POSS今后的研究方向进行了展望并提出可从POSS的构效关系、改性方法以及安全性等方面进行更加深入和系统的研究。The modification and application of organic/inorganic hybrid materials are one of the most dynamic research fields in material science.Polyhedral oligomeric silsesquioxane(POSS)achieves the combination of organic and inorganic components at the molecular level.Its structure is a three-dimensional cage type supported by the Si—O—Si bond.POSS has excellent reactivity,thermostability,flame resistance,porosity and nano-size effects and can be applied in many fields after modification.Firstly,the modification methods of POSS are described from three aspects of graft modification,polymerization modification and coordination modification.Then,the application research progress of POSS in heat-resistant materials,flame-retardant materials,reinforcement materials and porous materials is reviewed.Finally,the research direction of POSS is pointed out and it is suggested that the structure-effect relationship,modification method and safety of POSS can be further studied systematically.
