The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smtd.202200246.The inorganic particle can react with the liquid metal by the mechanically induced reaction; b) The inorganic particle cannot react with the liquid metal by the mechanically induced reaction. The melting point of Ga, eGaIn, Galinstan, In, In-Bi, and Pb-Bi is respectively 29.8, 15.4, 6, 156.6, 72, and 125 °C. And they were ground with the inorganic particle at temperatures above their melting point.

Joint‐Inspired Liquid and Thermal Conductive Interface for Designing Thermal Interface Materials with High Solid Filling yet Excellent Thixotropy

“…Specifically, as shown in Figure a, our previous study manifested that during the grinding process, the empty orbits of the LM atoms would form coordination interactions with the lone pair electrons of the Al 2 O 3 . [ 30 ] In this study, we carefully control the grinding time and LM to Al 2 O 3 proportion, in order to not only facilitate the coating of the LM droplets but also regulate their morphology and interfacial interactions. From the appearance, pristine Al 2 O 3 in white changes into grey powders (LM‐Al 2 O 3 , Figure S1, Supporting Information) after the mechanochemical grinding.…”

Bifunctional Liquid Metals Allow Electrical Insulating Phase Change Materials to Dual-Mode Thermal Manage the Li-Ion Batteries

“…The LMs we chose were eutectic alloys of Galinstan whose melting temperature was 13.2 °C, which present deformability under room temperature and tremendous mismatch in surface energy compared to solid BN sheets. To enable LM to be stably anchored to the surface of BN platelets, we took advantage of mechanical ball-milling to conduct the mechanochemistry reaction [ 47 ]. Unlike previously reported modification method based on traditional chemistry grafting, the mechanochemistry procedure was simple, time-saving and high-yield to obtain the thermally conductive hybrid fillers.…”

Breadcrumb-inspired Construction of LM@BN Core-shell Microparticles for Highly Thermal Conductive Elastomeric Composites with Excellent Flexibility and Stability

“…At the same time, the intensity of the LM diffraction peak near 36° is also enhanced, which means that the surface area of the LM becomes larger and the aspect ratio increases during stretching. This makes the BN on the surface of the LM particles have a certain orientation [35,41]. SEM images of the composite before and after stretching are given in Fig.…”

“…However, the combination between inorganic materials and LMs can change the rheological properties of LMs, so as to obtain hybrid llers with stable properties [35,36] Thiols can form coordinate bonds with metals to build a self-assembled monomolecular (SAM) layer on the surface of LMMPs, which can effectively improve the dispersion performance and stability of LM particles [37]. By mixing LM and an elastomer with a dynamic disul de bond structure together, the stability of the composite can be improved to a certain extent, resulting in the formation of self-healable This research is inspired by a traditional Chinese snack, "fried milk", in which breadcrumbs are wrapped around the surface of the milk to prevent its leakage, forming a core-shell structure with good shape stability.…”
