基于高分子软物质特性构建嵌段共聚物的非平衡相

Non-equilibrium Phase Construction in Block Copolymer Based on Soft Matter Behaviors of Polymer

利用高分子的弱影响强响应、熵致相变和多分散等软物质特性,以嵌段共聚物为例介绍了高分子非平衡相构建的研究结果:实现了特定化学组成的嵌段共聚物显示出多种有序相形貌,讨论了不依赖于嵌段组成的非平衡相的形成原因及演变规律。期望单一组成的高分子构成的多样性有序相结构能经济地满足高分子材料的多需求性。

Taking block copolymer as an example, we report here non-equilibrium phase formation and transition by using its soft matter behavior, such as small cause inducing large effect, entropy induced phase formation and potydispersity. Driving forces and evolution process of those composition-independent phase formation and transition have been discussed. Diversities of phase morphology obtained from block copolymer with certain one composition could economically satisfy requirements of performance diversity to polymer materials.
