Plastics holding metallic conductivity via semi-liquid metals

The electrically conductive polymers currently used cannot be industrially processed like plastics. Here, we reported a strategy of producing polymer composition with tin-gallium semi-liquid alloy for plastic molding to produce parts metallic conductivity (>106 S m−1). Molecular modeling and rheological experiments demonstrated that the key successful processing was viscosity matching between metals achieve bicontinuous structure. Our approach shows promise conventional industrial materials, such as those injection molding, film stretching, fiber spinning.
