Gallium-based liquid metal has liquid phase at room temperature. This liquid metal has non-toxic, low viscosity, high electrical and thermal conductivity characteristics. In this study, we synthesized polymer-encapsulated liquid metal droplets to improve their dispersibility against matrix and thermal stability. These encapsulated liquid metal droplets can be utilized as self-healing material which is stable at high temperature or conductive material in electronic devices. We prepared liquid metal microcapsules having polystyrene shell by surface-initiated radical polymerization method. The polymer-encapsulated liquid metal droplets were characterized by Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), optical microscopy and scanning electron microscopy (SEM). |
