Nanoarchitectonics and Applications of Gallium‐Based Liquid Metal Micro‐ and Nanoparticles

Abstract

In recent years, gallium‐based liquid metal (GLM) is an attractive material because of its excellent characteristics such as ultra‐low melting point, high fluidity, high conductivity, self‐healing and so on. GLMs have unique properties at micro and nano scales, such as core‐shell structure, sinterability, biocompatibility and photothermal conversion ability and so on, which promote the development of relevant application directions. Therefore, various preparation methods of GLM particles and conductive connection of GLM nanoparticles through various sintering methods are reviewed in this paper. In addition, GLM particles also show great prospects in flexible circuits, sensor detection, medical treatment, energy production and other fields

A review on thermal and electrical behaviours of liquid metal-based polymer composites

“…Some researches have been done to manufacture circuits with selfhealing functions by LMPCs. 138,139 The conductive LMPC fabricated by using EGaIn and a soft silicone elastomer has excellent self-healing functionality. 121 The clock circuit is made to work well after being severely damaged, requiring all four lines to remain connected (Fig.…”

Photo-Induced Reversible Deformation of Liquid Metal/Azo Polymer Hybrid Nanospheres for Application as Transformable Nanomachine

“…Over the past two decades, many researchers have conducted exhaustive studies on EGaIn and other gallium alloy applications in various domains, with a significant focus on flexible electronics, − biomedical materials and devices, − and soft robotics. , At the macroscopic level, LM is not easily controllable, which somewhat curtails its broad-scale applications. On the other hand, LM micro/nanodroplets are recognized for exhibiting superior stimulus response capabilities. − However, the high surface tension of gallium alloys, which exceeds 600 mN/m, presents manufacturing challenges for deformable devices incorporating EGaIn, as it inhibits wetting and encourages spherical droplet formation . To overcome such a challenge, researchers have delved into potential solutions that include modifying the surface of LMs .…”
