Liquid metal-based mixed nanofluid with high-surface-energy nanomaterial as intermediary as well as preparation method and application of liquid metal-based mixed nanofluid

The invention relates to the technical field of nanofluid preparation, in particular to a liquid metal-based mixed nanofluid with a high-surface-energy nanomaterial as an intermediary as well as a preparation method and application of the liquid metal-based mixed nanofluid. The liquid metal-based mixed nanofluid is characterized by comprising liquid metal, a nano intermediary and a non-metal nano dispersed phase, wherein the nanometer intermediary comprises one or more of molybdenum, tungsten and vanadium. According to the invention, the interaction energy relationship between liquid metal and non-metal mixed nano-particles is improved by utilizing a high-surface-energy nano-material, so that the dispersity and the flowability of the liquid metal-based mixed nano-fluid are improved. 本发明涉及纳米流体制备技术领域，尤其涉及以高表面能纳米材料为中介物的液态金属基混合纳米流体及其制备方法与应用。一种液态金属基混合纳米流体，其特征在于，包括：液态金属、纳米中介物和非金属纳米分散相；其中，所述纳米中介物包括钼、钨和钒的一种或几种。本发明提出利用高表面能纳米材料，改善液态金属与非金属混合纳米颗粒的相互作用能量关系，以期提高液态金属基混合纳米流体的分散性和流动性。
