聚合物三元共混物核壳形态在熔融混合中的调控及其功能化

本申请拟在不相容聚合物三元共混物中通过界面张力进行形态预测，通过熔体共混形成具有核壳形态的共混物，然后在动力学因素的调控下实现多层次的核壳形态，即核壳分散相结构和核壳三连续结构。然后通过熔融共混把功能化填料粒子引入到多层次核壳结构的壳层或者中间层中，从而制备功能化的核壳形态共混物。通过对核壳形态形成过程的控制以及填充功能填料粒子对核壳形态演变规律的研究，利用侧向多级熔体注入技术和调整组分比、粘弹比、加工参数等因素，以达到功能化聚合物三元共混物相形态控制和功能填料可控分布的同步实现，从而制备功能化共混材料。本申请能够实现熔融共混制备高性能和功能化核壳结构复合材料，具有重要的科学意义和应用价值。

In this project,we will prepare a ternary blends with hierarchical core-shell structure (core-shell dispersed phase and tri-continous structure)via the prediction of interfical tension and the control of kinetic factors. Then the nano fillers are selectively introduced into the shell phase or interfical phase of hierarchical core-shell structure by employing melt mixing to obtain the functional core-shell structure composites.Through the study of the formation of core-shell structure and the effect of nano fillers on the evolution of core-shell structure in the composites. The relationship between mixing type and fillers content of nano particles and the evolution of core-shell structure can be estabished. Also the effect of the evolution of nano fillers added core-shell structure on the formation of functional core-shell composites can be well investigated. This project can obtain a kind of functional core-shell composites via simple melt mixing, and it has important scientic research value and practical application value.
