摘　　要：不混溶共混物的增容是迄今为止将相容性较差的多相聚合物共混物转化为高性能合金的最通用和最有效的方法。本文主要简述了增容的概念和其必要性以及聚合物在通过共混改性时所采用的各种增容手段:添加嵌段和接枝共聚物;添加反应性聚合物;添加低分子量化合物;添加功能纳米粒子等,并综述了不同增容方法的发展现状及增容作用对共混物的相形貌和最终性能(力学性能、热性能、电学性能等)的影响,并最后提出纳米粒子增容将成为共混物增容领域的热门方法,这种方法不仅起能到增容作用,还可以增加机械强度并且有可能给共混物带来新的性能。Compatibilization of immiscible polymer blends is by far the most general and eficient strategy to convert multiphase polymer blends with poor miscibility into high performance polymer alloys.The concept and necessity of compatibilization of immiscible polymer blends were analyzed.Various compatibilization methods were introduced to improve the miscibility of polymer blends,including the addition of block or graft copolymers,reactive polymers,low molecular weight chemical compound and functionalized nanoparticles,etc.In addition,the development of compatibilization methods was reviewed and the effect of compatibilization on the phase morphology and final properties of the blends was discussed,such as mechanical properties,thermal properties,electrical properties,etc.Finally,tt was proposed that nanoparticle compatibilization will become a popular method in the field of blend compatibilization.This method not only can increase the capacity,but also increase the mechanical strength and possibly bring new properties to the blend.
