Suspension, colloid or reticular structure composed of liquid metal droplets combined with graphene-based particles, respective inks, transparent stretchable conductors, and processes for obtaining them

Abstract

A suspension or colloid consisting of liquid metal droplets combined with graphene-based particles, wherein the liquid metal is gallium or a gallium alloy, and the graphene-based particles are selected from graphene, graphene oxide, reduced graphene oxide, graphene quantum dots, carbon nanotubes, or combinations thereof. Each ink, transparent stretchable conductor, and their acquisition processes; also, a conductor obtained by applying a coating of the suspension, colloid, network, or ink according to any of the previous claims onto a substrate and laser sintering the coating, in particular the conductor is an electrode or a circuit trace or a circuit. Uses include electrodes for optoelectronic devices, piezoresistive composites sensitive to pressure or strain, pressure or strain sensors, temperature sensors, electroluminescence devices, photovoltaic devices, memory devices, or energy storage devices.
