Recent Advances in Liquid Metal-Based Reconfigurable Functional Materials Enabled by Dynamic Interfacial Design

Abstract Liquid metals, recognized for their advantages such as room-temperature fluidity and chemical reactivity, hold significant potential as emerging cutting-edge reconfigurable functional materials in advanced technologies. However, owing to their high surface tension, low shape stability, and susceptibility to oxidation, the achievement of elaborate structural regulation and functional construction during compositing is highly challenging, in which the interfacial design is one of the core issues. Herein, this mini-review briefly outlines the latest advances in LMs-based soft materials with high mechanical properties and reconfigurability, focusing on supramolecular interfacial design strategies for achieving dynamic and multifunctional materials through inorganic–organic interactions, including hydrogen bonds, ionic bonds, and metal coordination bonds and, furthermore, dynamic interfacial phases construction. Then, the reconfigurability including reprocessability and self-healing, along with their advanced applications, is discussed. Finally, conclusions and future outlooks for LMs-based soft materials are presented.
