摘　　要：镓基液态金属具有高导电性、高导热性、高流动性和优良的生物相容性,是一种具有很大发展和应用前景的功能材料。镓基液态金属与其他不同物理化学性质的材料组合而成的镓基液态金属复合材料为基础研究与应用研究提供了一个新的方向,为解决柔性电子、热调控和生物医学等各个领域的挑战性问题提供了新的思路并表现出重大潜力。磁性粒子的引入可以使镓基液态金属具有良好的磁性能。作为一种新兴的磁性功能材料或磁性智能材料,磁性镓基液态金属复合材料在柔性电子、微电机、靶向给药、热调控、屏蔽与吸波等领域已展现出初步的研究和应用价值。本文系统地总结和评述了磁性镓基液态金属复合材料的研究进展。从基础研究、磁力控制、磁热控温、屏蔽与吸波四个方面综述了磁性镓基液态金属复合材料的性能和应用,说明了这种复合策略的有效性。这可为磁性镓基液态金属复合材料的进一步研究与开发提供思路。Ga-based liquid metal has high electrical conductivity, high thermal conductivity, high fluidity, and excellent biocompatibility, and is a functional material with great development and application prospects. Ga-based liquid metal composites developed in combination with other different physical and chemical properties materials offer a new platform for basic and applied research, providing new ideas and showing great potential for solving challenging problems in various fields such as flexible electronics, thermal management, and biomedical science. The introduction of magnetic particles can provide Ga-based liquid metal with good magnetic properties. As an emerging magnetic functional material or magnetic intelligent material category, magnetic Ga-based liquid metal composites have shown preliminary research and application value in the fields of flexible electronics, micromotors, targeted drug delivery, thermal management, and shielding and absorption. In this paper, we systematically summarize and review the research and progress of magnetic Ga-based liquid metal composites. The effectiveness of this composite strategy is illustrated by reviewing the properties and applications of magnetic Ga-based liquid metal composites in four categories: basic research, magnetic control, magnetic thermal management, and shielding and absorption. This review provides an overview of ideas for the further research and deve- lopment of magnetic Ga-based liquid metal composites.
