Abstract

We have developed a novel on-substrate composition patterning process of room-temperature liquid metal alloys via a simple two-step method: 'coat pop'. This work present for the first time the integration of a single or several noble metals (Au, Ag or Cu) on Ga-based liquid metal droplets on a single substrate, by using a spontaneous chemical reaction then simple mechanical compression, to form biphasic and liquid composition patterns. The controllable deposition of noble metals encapsulation patterns and formation of several interfaced conductive biphasic intermetallic alloys on a single substrate were successfully demonstrated.
