Gallium-based liquid metal alloys are a special type of material that is in the liquid state at (or near) room temperature. They are particularly attractive due to their unique combination of a fluidic and metallic body, together with a chemically reactive and functionable surface. As a fluid, liquid metals provide the best union of stretchability, deformability, and electrical conductivity among all soft materials. Such an advantage in combination with their low toxicity and relatively good biocompatibility has imparted liquid metals with unique features that can be harnessed for applications in many fields.
More importantly, the fluidic nature of liquid metals allows them to be readily processed using shear for making particles with variable sizes (from nm to mm), which is not possible with solid materials. These particles have a liquid metal core–solid metal oxide shell (conductor–semiconductor) structure, allowing them to merge, transform shape, change phase, respond to stimuli, and self-heal. Despite these unique features, limited surface stability and functionality, unpredictable reactivity, and uncontrollable hydrophilicity of liquid metal particles niche their wider applications.
To bestow liquid metal particles with desirable surface properties while taking the benefits offered by soft features, another important soft material – polymers – can be synthesized and engineered on an on-demand basis to coat or embed liquid metal particles. This leads to the formation of liquid metal–polymer soft composites with versatile surface properties, thereby yielding soft–soft systems with exciting properties. In this talk, Dr Tang will introduce his recent works on the production, investigation, characterization, and application of liquid metal particle–polymer composites.

Dr Shiyang Tang currently is a Lecturer (Assistant Professor) in the Department of Electronic, Electrical and Systems Engineering at the University of Birmingham, UK. He received his BEng (1st class honours) in Electrical Engineering and PhD in Microelectromechanical Systems (MEMS) from the Royal Melbourne Institute of Technology, Australia, in 2012 and 2015, respectively. He went to the Pennsylvania State University (PSU) and the University of California, San Francisco (UCSF) to conduct his postdoctoral research in bio-microfluidics. He returned to Australia and joined the University of Wollongong as a Vice-Chancellor's Postdoctoral Research Fellow in 2017. He was the recipient of the Discovery Early Career Researcher Award (DECRA) from the Australian Research Council. Dr Tang's Soft Intelligent Systems research group (https://www.ubham-sis.uk/) at Birmingham conducts research on intelligent microfluidics and liquid metal-enabled electromechanical platforms. He has published more than 100 articles in high-quality journals (more than half of them are as the first/corresponding author), such as PNAS, Nature Communications, Science Advances, Advanced Materials, Matter, Advanced Functional Materials, and Small. Dr Tang is the Associate Editor of Journal of Nanobiotechnology (IF = 9.429), and an Editorial Board Member of Scientific Reports, Sensors, and Soft Science.
