Enhancement of the piezoelectric performance of GN nanosheets/PVDF nanocomposite film using electrostatic layer and penetrated electrode
Source abstract
Abstract
The efficiency of the piezoelectric nanogenerator is a vital factor for the superior performance of the nanogenerator to achieve a green and eco-friendly technology in the development of modern electronics. Piezoelectric nanogenerators (PNGs) have limited use in mechanical energy harvesting due to their low output performance. The output has been a major source of concern for PNG`s development. A new design of PNG based on g-C 3N 4 nanosheets(GN)/PVDF nanocomposite film (GPNC) using penetrated Cu electrode and electrostatic layer is proposed to overcome this problem. By creating numerous peripheral contacts within the piezoelectric material, the overall number of surface polarization charges increased. Also, an electrostatic contribution from graphene oxide contributes to an increased output voltage. The syngeristic effect of high % γ-nuclei, penetrated electrode, and electrostatic effect is supposed to vital for carry out significant piezoelectric outputs (V∼34.4 V and I ∼3.2 µA) and superior force sensitivity (0.93 V/kPa). In practical applications, the designed PNG can competently harvest electrical energy from various human movements, and also can detect low physiological actions. Our work offers a simple but effective perspective for high-performance piezoelectric nanogenerator fabrication and progress a stride toward self-powered day-to-day used electronics.
