Liquid metal (LM) has attracted tremendous interest over the past decade for its enabling combination of high electrical and thermal conductivity and low mechanical compliance and viscosity. Efforts to harness LM in electronics, robotics, and biomedical applications have largely involved methods to encapsulate the liquid so that it can support functionality without leaking or smearing. In recent years, there has been increasing interest in LM “nanocomposites” in which either liquid metal is mixed with metallic nanoparticles or nanoscale droplets of liquid metal are suspended within a soft polymer matrix. Both of these material systems represent an important step towards utilizing liquid metal for breakthrough applications. In this minireview, we present a brief overview of recent progress over the past few years in methods to synthesize LM nanomaterials and utilize them as transducers for sensing, actuation, and energy harvesting. In particular, we focus on techniques for stable synthesis of LM nanodroplets, suspension of nanodroplets within various matrix materials, and methods for incorporating metallic nanoparticles within an LM matrix.

液态金属纳米复合材料

液态金属 (LM) 在过去十年中因其兼具高导电性和导热性以及低机械柔量和粘度而引起了极大的兴趣。在电子、机器人和生物医学应用中利用LM的努力主要涉及封装液体的方法，以便它可以在不泄漏或涂抹的情况下支持功能。近年来，人们对LM“纳米复合材料”越来越感兴趣，其中液态金属与金属纳米粒子混合，或者液态金属的纳米级液滴悬浮在软聚合物基体中。这两种材料系统都代表了利用液态金属实现突破性应用的重要一步。在这篇小综述中，我们简要概述了过去几年在合成 LM 纳米材料并将其用作传感、驱动和能量收集传感器的方法方面取得的最新进展。我们特别关注LM纳米液滴的稳定合成技术、纳米液滴在各种基质材料中的悬浮以及将金属纳米粒子掺入LM基质中的方法。
