摘要:

高分子通过适当的分子结构设计,可自组装形成种类丰富的多级微相结构,表现比普通的单周期结构更优异的力学和光学等性能。 理解和掌握高分子多级微相结构的形成机理是设计新颖多级结构材料的基础,同时揭示多级结构与性能的关系可为制备具有优异性能的多功能材料提供指导。 从以上两个方面出发,结合理论模拟手段,详细阐述了各种高分子多级微相结构,特别是含液晶单元的多级结构的形成过程及机理,进而简述了高分子多级结构的性能,如力学性能和光电性能。 最后,总结分析了高分子多级微相结构的研究进展,并展望了主要研究方向。

Abstract:

Polymers can self-assemble into hierarchical microstructures with a wide variety of morphologies, which usually show improved mechanical and optical properties relative to general single-period microstructures. Understanding and mastering the formation mechanism are the basis of designing hierarchical microstructures with novel morphologies. Further study on the relationship between hierarchical microstructure and their property can guide the fabrication of multifunctional materials with excellent properties. In the present review, the formation process and mechanism of various hierarchical microstructure are featured, and their mechanical and photoelectric properties are discussed. Finally, the research progress and prospects on polymeric hierarchical microstructure are presented.

Key words: Polymer, Liquid crystal, Hierarchical microstructure, Mechanical properties, Photoelectric properties
