高分子复合材料微加工

Polymer Composites Micro-Process

高分子纳米复合是深入理解高分子链结构和宏观性能的关键,直接影响着复合材料向尺寸微小化、控制精细化、复合功能化和系统集成化方向发展的进程,涉及了高分子复合材料微加工中的诸多问题,其中多组分多尺度空间分布和形态精细控制的物理与化学是两个关键科学问题。自2000年起,我们围绕这两个关键问题展开系列研究,主要面向复杂性复合颗粒和纳米孔复合膜两种典型形态结构,发展了模板合成微加工方法,实现对宏观形态的有效控制,并且通过软物质(高分子凝胶和嵌段共聚物)特殊作用诱导组分定位生长控制微结构,系统研究其物理与化学问题,发展了多组分多尺度空间分布高效精确调控的方法,同时实现了组分的空间分布和形态控制。

Nanoscale functionalization for polymers is crucial to further understand essential correlation between polymer chain structure and macroscopic properties, which direct influence capability and trend to functionalize polymer materials. It is urgently required to further investigate physics and chemistry of the micro-process. Since 2000, we have been focused on polymer composites micro-processing and physics and chemistry therein. Two representative macroscopic morphologies are mainly concerned ： complex composite particles and nanoporous composite membrane. We have developed new template synthesis approaches to precisely control their macroscopic morphologies, meanwhile to assist a favorable growth and spatial distribution of desired components with soft matter （polymer gels or block copolymers） by specific interactions. The physics and chemistry during the micro-process has been elucidated.
