Abstract

The room temperature liquid metals, alloys and their allied composite materials are a big class of newly emerging fundamental matters inherited with many fascinating properties and exciting application potentials. Particularly, their pretty easy transition/switch features between solid and liquid phases endorse such materials with tremendous functions and capabilities. Examples are rather diverse covering nearly all physical, chemical and engineering fields. In this talk, I will give an overview on the liquid metal R&D activities in my lab and discuss fundamental sciences lying behind. The major categories are as follows: From the thermal fluidic aspect, I will illustrate that the emergence of the liquid metal electronic cooling opens revolutionary way to break up the "thermal barrier" seriously challenging the world. While from the electrical engineering aspect, the inventions of the liquid metal printed electronics and room temperature 3D metal printing innovated the classical electronics and integrated circuit manufacturing rules. For the human health care, the proposition of the liquid metal biomaterials offered entirely new visions for tackling the current biomedical challenges. Along with these endeavors, a group of very fundamental discoveries on liquid metal basic phenomena inspired the new era of transformable liquid metal soft machines. All these endeavors incubated the milestone industrial progresses. For illustration, I will summarize the set up and practices of “The China Liquid Metal Valley” as well as the new industry involved. Finally, a perspective will be given on the future of this area. Overall, the rise of the liquid metal sciences is reshaping modern industry and expected to bring about better daily life in the coming time. What one needs to do in this day and age is just try to investigate, utilize and advance such powerful and magic materials.

室温液态金属、合金及其复合材料是一大类新兴的基础功能物质，有着许多令人着迷的性质和重大应用价值。特别是，此类材料易于在固相和液相之间切换的特性，赋予其强大的非常规能力。这样的例子相当广泛，几乎涵盖所有物理、化学和工程领域。本报告中，我将简要介绍本实验室近期的一些液态金属研发活动，并解读背后的基础科学问题，所涉及的主要范畴为：在热流体科学层面，我拟解读液态金属电子冷却的出现，为打破严重制约世界芯片发展的“热障”难题开辟了革命性的途径；而在电子工程学领域，液态金属印刷电子技术与室温3D金属打印的发明，正在重塑传统电子和集成电路制造规则；对于生物医学而言，液态金属生物材料的提出为应对许多重大挑战带来了全新视野；与此同时，液态金属若干基础现象与科学效应的发现则从根本上孕育了可变形液态金属软体机器人新时代的到来。所有这些快速增长的探索表明，液态金属正在为下一代科学、技术和工业提供强劲动力。最后，在工业实践方面，我拟介绍“中国液态金属谷”的建立和发展概况及其在推进全新产业方面所做出的努力。总的来说，液态金属科学的崛起可望变革现代工业并创造人类未来更好的生产生活方式，我们每个人要做的就是尽力去探索、利用和发展液态金属这样强大而神奇的材料。
