We report a high output performance of flexible nanogenerator (NG) based on the composite of PVDF and Zn:Al layered double hydroxide (LDH) nanosheets. The Zn:Al LDH nanosheets were synthesized via the most facile process by dipping the sputtered Al-doped ZnO (AZO)/Ag/AZO multilayer films into deionized water at room temperature. Here, sputtered AZO/Ag/AZO multilayer was served as a bottom electrode of the energy harvesting device as well as for the growth of Zn:Al LDH nanosheets. The PVDF based NG exhibited an output voltage of ~ 1.71 V and a current density of ~ 0.19 μA cm-2 after poling. While poled-PVDF/Zn:Al LDH composite based NGs exhibited an enhancement in the output performance with an output voltage and current density of ~ 6.24 V and ~ 0.655 μA cm-2, respectively. This simple facile approach can be feasible for the development of large-scale, flexible and an eco-friendly energy harvester that can be widely implemented in self-powered biomedical applications.
