Gallium-based liquid metal (LM) are emerging materials due to their unusual combination of metallic and fluidic properties, which could be used in a variety of fields such as flexible electronics and soft composites. When compared to bulk LM, the fabrication of LM nanoparticles enables solution-processing and lowers its freezing and melting temperatures, which can expand operating temperatures in LM-based electronics. LM can be dispersed in eco-friendly solvents including alcohol and water. However, the fabrication of LM nanoparticle securing the colloidal stability is still challenging. Herein, we report facile and effective fabrication of water-dispersed LM nanoparticle through emulsification-induced polymer self-assembly. The LM nanoparticle were generated by triggering the interfacial instability to the emulsion by controlling the interfacial tension. This research can provide a facile strategy for the formation of LM nano particle-water ink that can be applied to soft electronics. |
