All-solution process flexible nanocomposite generator made of BaTiO3 nanoparticles and graphene quantum dots

Abstract

We have demonstrated an all-solution-processed of flexible piezoelectric nanogenerator based on BaTiO3 and graphene quantum dots (GQDs) with several different concentrations by adding together GQD and PVDF on PET substrate. These devices then have been obtained by spin coating method which able to convert small mechanically wise deformation into electric energy. Even with limited area of active element surfaces, output voltage (VRMS) and peak voltage (VPP) of the device show 125.87 mV and 1.29 V, respectively. Furthermore, the different concentration of active element with and without GQDs and also different concentration of BaTiO3 affected the output performance of flexible piezoelectric nanogenerator. This result expands the possibility of self-powered energy systems for electronics, sensors and energy harvesting leads to prodigious future prospect in electronic sector's development.
