Explanation

compatibilizer is a substance that plays a key role in the multiphase and multi-component system of polymer. Its role can be divided into two main aspects: first, compatibilizer helps to better disperse different polymer, thus creating a uniform mixture at the macro scale, preventing the phase separation of different components, thus enhancing the stability of polymer blending. Secondly, compatibilizer can improve the phase interface performance between different polymer and enhance the adhesion between them, thus improving the comprehensive performance of the mixture and making it have better characteristics. The action mechanism of compatibilizer includes physical compatibilization and chemical compatibilization. Physical compatibilizer are usually special polymer, such as block copolymer and graft copolymer. Their mechanism is to improve the compatibility between incompatible polymer and promote their better mixing and dispersion by introducing these special polymer, such as block copolymer AB or A - ^ - B. On the other hand, chemical compatibilizer usually contain functional groups that can react with polymer components in the mixture. This type of compatibilizer is suitable for mixed systems between incompatible polymer components that contain reactive functional groups. Chemical compatibilizer forms new chemical bonds with polymer components in the mixture to improve their compatibility, thus improving the performance of the mixture. In polymer industry and materials science, compatibilizer are widely used. They help to improve and optimize the performance of multiphase mixtures and expand the application field of materials.
