室温液态金属表界面行为调控及材料功能设计
In recent years, room temperature liquid metal materials have attracted widespread attention in academia and industry due to their unique physical and chemical properties. This type of material can not only remain in liquid state under ambient conditions, but also exhibits excellent fluidity, deformability, and excellent electrical and thermal conductivity, making it an ideal candidate for the next generation of smart materials. Its application potential in flexible electronics, soft robotics, and biomedical devices is particularly prominent. However, problems such as high surface tension and easy oxidation limit its wide application. This lecture will focus on the innovative methods of regulating the surface and interface behavior of liquid metal materials and their functional design. Starting from the surface and interface properties of liquid metal itself, the study deeply explored key issues such as surface tension regulation, oxide film regulation, and wetting behavior control, and on this basis proposed a series of smart material design strategies based on liquid metal. At the same time, this study also explored the application prospects of this type of new smart material in multiple fields.
近年来,室温液态金属材料因其独特的物理化学性质在学术界和工业界引发了广泛关注。这类材料在环境条件下不仅能够保持液态,还展现出卓越的流动性、可变形性以及优异的电导性和导热性,使其成为下一代智能材料的理想候选。其在柔性电子、软机器人和生物医学设备等领域的应用潜力尤为突出。然而,高表面张力和易氧化等问题限制了其广泛应用。本次讲座将重点探讨液态金属材料的表面和界面行为调控及其功能设计的创新方法。研究从液态金属自身的表界面性质出发,深入探索了表面张力调控、氧化膜调控以及润湿行为控制等关键问题,并在此基础上提出了一系列基于液态金属的智能材料设计策略。同时,本研究还探讨了这类新型智能材料在多个领域的应用前景。

液态金属新材设计
Liquid metals provide strong metallic interactions, a dynamic synthesis environment, unique surface/interface effects under normal synthesis conditions. These traits of liquid metals, not seen in conventional solvents, offer new possibilities for synthesizing novel functional materials. Based on crystal growth from metallic solvents, we aim to develop a strategy to achieve controllable design of metallic fine structures, by leveraging spontaneous structural formation processes. In this talk, I will share some of our recent effort and progress toward this direction. The main topics to be covered include phase transition, crystal growth (including surface/interface phase transition and crystal growth), spontaneous pattern formation and structural development during crystallization and dealloying in liquid metal synthesis systems, as well as application cases of the developed metallic fine structures in sensing/detection and catalysis. It is hoped that the talk will provide insight into liquid metal-based material design from both fundamental and practical perspectives.
作为一类特殊的金属溶剂,液态金属能够在常规合成工况下提供其他溶剂体系不具备的强金属相互作用、动态合成环境和特殊表界面效应,使其成为构建新型功能材料的新体系。基于金属溶剂晶体合成,我们致力于开发一种利用自发结构化过程实现精细金属功能结构可控制备的材料设计策略。报告将围绕这一思路,介绍我们近期在这一研究方向作出的努力和取得的进展,其内容主要涉及:金属溶剂体系相变、结晶(涵盖表界面相变和结晶);结晶和去合金化过程中的自发图案化和结构化;具有设计组分和结构的精细金属功能材料在传感检测和催化方面的应用。通过对上述基础问题和应用案例的介绍,报告希望对基于液态金属的材料设计有所启发。
