A scalable solution‐based approach is developed to controllably grow PPy ultrathin films on 2D MoS 2 monolayers. When these sandwiched nanocomposites are utilized as supercapacitor electrodes, a record high specific capacitance, remarkable rate capability, and improved cycling stability are achieved, offering a feasible solution to create the next generation of energy‐storage device with superior power density and energy density.
