In-Situ Construction of Ordered Nanostructures in Materials and Their High Performance and Functionalization Design

随着国防科技和国民经济的快速发展,传统人工材料已难以满足当今社会科技的发展需求,人工材料性能的提升越来越困难,面临发展瓶颈。在材料中原位自发构筑有序纳米结构以实现材料高性能化和功能化正成为先进材料的重要发展方向。四川大学高分子功能复合材料研究团队针对目前材料有序纳米结构组成单一、形态有限、对材料性能提升有限等不足,提出并建立了在材料中原位自发构筑组成多样、形态复杂的有序纳米结构进而实现材料高效强韧化及功能化的新方法。文中将对研究团队在材料中原位可控构筑有序纳米结构方法、基于有序纳米结构设计实现材料高效强韧化及其机理、基于有序纳米结构设计实现材料结构功能一体化、基于有序纳米结构可控构筑技术实现环氧树脂中有机半导体网络构筑、基于碳纤维界面层有序纳米结构设计制备高性能碳纤维复合材料等基础理论研究及关键技术方面取得的进展进行简要介绍,并对其相关研究发展方向进行了展望。

With rapidly advancing national defense technology and national economy,the traditional artificial materials are unable to meet the requirements of technological development of today's society.The study of the artificial materials is facing the bottleneck.In-situ constructing ordered nanostructures in materials to achieve high-performance and functional materials is becoming an important research direction for advanced materials.Aiming at the current outstanding issues such as ordered nanostructures with single component and limited morphologies,Polymer Functional Composites Research Group(PFCRG)in Sichuan University proposed a new technology for in-situ construction of ordered nanostructures with diverse compositions and complex morphologies in materials to achieve their efficient strengthening,toughening and functionalization,which could meet the national strategic development goals for new materials.In this paper,the progress and breakthroughs on in-situ construction of ordered nanostructures in materials and its applications made by PFCRG were summarized.Meanwhile,the development trend on in-situ construction of ordered nanostructures in materials was also prospected.
