共混聚合物界面相容性研究进展

Progress in research on improving the miscibility of polymer blends

综述了改善共混物界面相容性的3种方法。提高大多数不相容聚合物相容性的方法主要是加入嵌段或接枝共聚物等增容剂;对其中一相进行化学改性的方法在生物高分子领域有较多的应用;由于无机纳米粒子有增强增韧的作用且较容易获得,因此,加入无机纳米粒子改善共混聚合物相容性的方法具有很大的发展空间。

Three methods for improving the miscibility of polymer blends were reviewed. Adding compatibilizers such as block or graft copolymers is a major approach currently. Chemical modification of one component of the polymer blends is widely applied to bio-macromolecules. Due to effects of reinforcement and toughening of inorganic nano-particles on polymers and the easy-gaining of the former, the introduction of inorganic nano-particles is expected a bright future in the field.
