Liquid metal (LM) with high electrical conductivity, thermal conductivity, excellent biocompatibility, and extraordinary fluidity has emerged as a promising class of functional materials. However, such materials still encounter many practical challenges due to the rather limited forms available so far. As a promising remedy, LM composites in synergy with other materials would open tremendous opportunities for fundamental research or practical applications. This is because controllable integration of base LM with functional materials (e.g., metal nanoparticles, polymers, and drug molecules) would significantly tune the intrinsic properties of LM as desired, enabling it to offer further major potential in tackling various sectors' challenging issues, including thermal management, biomedicine, chemical catalysis, flexible electronics, and soft robots. Here, we systematically summarize and review the fundamental progress in pursuing LM composites. The basic composite strategies are outlined in three categories: LM composites with core-shell structure, LM-polymer composites, and LM-particle composites. The effectiveness of the composite strategy is illustrated via the typical applications of LM composites in representative fields. The challenges and perspectives in developing LM composites are also identified and interpreted to better guide future research. It is expected that the coming LM era will witness a new world of fruitful composites thereby discovered or invented.

“…It has been known that gallium or its oxide could act as initiator or catalysts for reaction. [ 32,33 ] Considering the identified anionic ring‐opening polymerization mechanism of epoxy groups which initiated by metal oxides (such as alumina), this ring‐opening polymerization was also expected to follow the anionic polymerization mechanism initiated by amphoteric Ga 2 O 3 . [ 34,35 ] According to the above references, Ga 2 O 3 could exhibit an amphoteric surface on which O 2− should be a base and nucleophile, and Ga 3+ will act as a Lewis acid (Scheme S2, Supporting Information).…”

Growing interests have been received in metal‐polymer hybrid composites for their combined features of metals and polymer. However, the detrimental incompatibility between inorganic and organic polymer matrix makes it challenging to prepare homogenous hybrid composites for advanced applications. This work reports using disulfides, as interactive binding bonds, to interact with liquid metals (LMs) for fabricating the liquid metal‐disulfide (LMDS) composites. The interaction between disulfides and liquid metals lead to uniform dispersion of LM droplets in polymer matrix and strengthen the whole polymer network for improved mechanical performance. Interestingly, this work discovers that the LM droplets could act as efficient initiator to promote the ring‐opening polymerization to obtain the composites. In addition, the interactive LMDS composites exhibit excellent self‐healing ability ascribing to the dynamic LM‐disulfide interaction and disulfide metathesis. The phenomenal electrical conductivity and self‐healing feature enable LMDS composites as stretchable self‐healing conductors with the ability to control the electrical circuits.

“…The shape conversion and photothermal properties of liquid metal particles (LMPs) can be used as nanomachines for medical applications [71]. Simultaneously, the applications of LMP in thermal management [80], energy conversion [81,82] and catalysis [83] have developed rapidly in recent years, and LMP also has important value as a conductive material. Micro/nano-sized liquid metal particles can be produced in a controllable size by a bottom-up process such as physical deposition and thermal decomposition [84][85][86][87].…”

Gallium and its alloys are a group of metallic materials with low-melting points at or around room temperature. Apart from the good electrical conductivity, the unique liquid state endows those metals with excellent compliance and self-healing capacity, which present great value in the development of flexible and stretchable electronics. Constrained by the high surface tension and low viscosity, however, liquid metals cannot be applied to some common microelectronics manufacturing technologies such as micro-electro mechanics in the preceding years, which impedes their mass production in electronic devices. To address these issues and broaden the applications of liquid metals in electronics devices, numerous efforts have been taken and great progress has been made especially in the very recent years. This review summaries the recent development of liquid metal-based conductive materials from the aspects of preparation or modification methods and their accommodative fabrication techniques in flexible electronic applications. Further outlook including expectations and challenges of liquid metal-based conductive materials are also presented.
