摘要
高分子材料具有广泛的应用前景,但其阻燃性往往成为限制其使用的因素之一。聚倍半硅氧烷(POSS)具有独特的分子可设计性,近年来在聚合物阻燃领域受到广泛关注。本文针对聚倍半硅氧烷的研究现状,综述了其阻燃机理及一般合成方法。重点讨论了含磷低聚倍半硅氧烷(含磷POSS)的合成方法及其在聚合物中的应用效果。将常见的含磷POSS,按照结构形态分为五类:完整笼形、不完整笼形、笼-梯形、POSS基共聚物、POSS基官能化氧化石墨烯,并讨论了它们对不同聚合物带来的阻燃性能的影响。结果表明,不同的含磷POSS与一定的聚合物混合均能表现出优异的阻燃性能,具有广泛的应用前景。
Polymer materials have broad application prospects.However,flame retardancy is one of factors limiting their application.Polysilsesquioxane(POSS)has unique molecular designability and has received extensive attention in the field of polymer flame retardancy in recent years.Aiming at the research status of POSS,it is reviewed for flame retardant mechanism and general synthesis.The synthetic and application of phosphorus-containing oligomeric silsesquioxane(phosphorus-containing POSS)in polymers are mainly discussed.The common phosphorus-containing POSS can be divided into five categories according to their structural morphology:complete cage,incomplete cage,cage-trapezoid,POSS-based copolymer,and POSS-based functionalized graphene oxide.At the same time,their influence on the flame retardancy of different polymers was discussed.The results show that polymer with different phosphorus-containing POSS can exhibit excellent flame retardancy.
