摘要

本文研究了无镓液态金属（BiPbInSnCd 合金，熔点 47 °C）复合材料的热性能和稳定性。研究发现，在非镓基液态金属中加入铜颗粒和铜泡沫有助于提高整体热导率，并获得比镓基液态金属复合材料更长的使用寿命。我们已经证明，填充物重量比为 44.4 % 的无镓液态金属复合材料的平均热导率可高达 28.9 W-m-1-K-1。我们还研究了热性能的改善机制和制备方法对热性能的影响。

Enhanced thermal performance and stability of non-gallium liquid metal composites

This paper presents a study on the thermal performance and stability of non-gallium liquid metal (BiPbInSnCd alloy with melting point 47 °C) composite. It has been found that incorporating copper particles and copper foam into the non-gallium liquid metal can help to enhance the overall thermal conductivity, and achieved longer lifetime than gallium-based liquid metal composite. We have demonstrated that the average thermal conductivity of non-gallium liquid metal composite with filler weight ratio of 44.4 % can reach as high as 28.9 W·m⁻¹·K⁻¹. The improvement mechanism and the impact of preparation methods on the thermal performance have been also investigated.
