Synergism of graphitic-carbon nitride and electrospinning on the physico-chemical characteristics and piezoelectric properties of flexible poly(vinylidene fluoride) based nanogenerator

Herein, we investigated the piezoelectric performance of electrospun poly(vinylidene fluoride)/graphitic carbon nitride (PVDF/g-C3N4) nanocomposite fibers (PGN-X). Addition of g-C3N4 nanosheets improved the spinnability of nanofibers and augmented the -phase content of PVDF. The synthesized PGN non-woven mats were flexible and easily deformable without disrupting the continuity of fibers. Upon the addition of g-C3N4, tensile strength and thermal stability of nanocomposite fibers improved significantly. A maximum voltage output of similar to 7.5V was generated for PGN nanogenerator which is similar to 8 times more than that of PVDF nanogenerator. Also, the PGN-X nanogenerator generated current output of 0.23A and a power density of 0.22W/cm(-2). Improved physico-chemical characteristics and piezoelectric performance of PGN nanogeneratoris promising and makes it suitable for portable electronic and wearable devices.
