Surface modification of liquid metal microparticles of the eutectic gallium–indium alloy afforded a liquid metal powder containing a small amount of organic components, which can be returned to the bulk liquid metal form by applying mechanical forces. Liquid metal–polymer composites with stimuli-responsive electrical conductivity were readily prepared by manual mixing of the liquid metal powder with polymer precursors. In addition, the liquid metal powder acted as a microwave absorber in the composite materials, thereby inducing microwave heating.
