| Abstract Scope |
This talk will discuss liquid metal nanoparticles composed of gallium and gallium-based metal alloys. These metals are low-viscosity liquids at room temperature with low toxicity and negligible vapor pressure. They react with air to form an ultra-thin surface oxide skin that keeps them from merging together. They can be formed very simply by sonicating or mixing liquid metal in a solvent or polymer. We have shown that these particles are useful for coating textiles to create anti-bacterial surfaces and self-healing conductors. In addition, the particles can be used to initiate polymerization to form hydrogels and can be mixed with polymers to form functional composites. They also have plasmonic properties that are shape dependent, which can be used to create optical surfaces that change with strain. |
