Abstract

Building macro continuous materials that play an important role in our daily lives directly from powder is in line with the development needs of green chemistry. Powders or particles tend to spontaneously aggregate and fuse to reduce the interfacial energy of the system, but compared to solutions or melts, the molecular motion ability in the solid phase is significantly limited. Inspired by the agglomeration of powder and kneading dough, the introduction of a small amount of water and pressure has enabled the preparation of continuous self-supporting materials based on surfactants, and even the construction of ordered molecular membranes through solid-phase molecular self-assembly. This article summarizes the recent work on the construction of macroscopic materials using molecular motion in solid phase, and mainly introduces its principles, self-healing properties, and application directions, including strain sensing, oil absorption, humidity response, circularly polarized luminescence, etc., and looks forward to the future development space.

赋予固体材料中的分子运动
直接利用粉末制造在日常生活中发挥重要作用的宏观连续材料符合绿色化学的发展需求。粉末或颗粒容易自发聚结融合以降低体系的界面能,但与溶液或熔体相比,固相中的分子运动能力明显有限。受粉末团聚和捏面团的启发,引入少量水和压力就能制备基于表面活性剂的连续自支撑材料,甚至通过固相分子自组装构建有序分子膜。本文总结了近年来利用固相分子运动构建宏观材料的工作,主要介绍了其原理、自修复性能以及应用方向,包括应变传感、吸油、湿度响应、圆偏振发光等,并展望了未来的发展空间。

期刊介绍: Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
