Liquid-liquid triboelectric nanogenerator based on the immiscible interface of an aqueous two-phase system.

ABSTRACT: Solid nanogenerators often have limited charge transfer due to their low contact area. Liquid-liquid nanogenerators can transfer a charge better than the solid-solid and solid-liquid counterparts. However, the precise manipulation of the liquid morphology remains a challenge because of the fluidity limits of the liquid. In this work, using the surface tension of a droplet to fix its shape, a liquid-liquid triboelectric nanogenerator in Contact-Separation mode is designed using an immiscible aqueous-aqueous interface, achieving a contact surface charge transfer of 129 nC for a single droplet. The configuration is proven to be applicable in humid environments, and the two-phase materials have good biocompatibility and can be used as an effective drug carrier. Therefore, this nanogenerator is
