Abstract

As candidates, liquid metal composites (LMCs) exhibit tunable physical and functional properties at various scales, broadening applications in flexible electronics. Herein, by the synergistic effect of metal coordination and acoustic field, a liquid metal composite (LMEPC) with tunable gradient structure is prepared. The gradient and bicontinuous structures of LMPEC result in the initial thermal and electrical conductivity anisotropy without pre-activation. The size of LM particles (LMPs) can be controlled from nano to micro scale due to the synergistic effect of metal coordination and acoustic field application, resulting in a transformation of the gradient structure. LMEPC exhibits enhanced electrical conductivity (0.0540 Ω), thermal conductivity (1.317 W K⁻¹ m⁻¹), mechanical property (1847.3 MPa), and programmable shape performance. These capabilities enable the design of multifunctional electronics. This work provides a new strategy to control the gradient structure of LMCs by the induction of metal coordination to broaden the horizon of applications.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
