Gold Nanoparticle Doped PVDF Nanofiber Preparation of Concurrently Harvesting Light and Mechanical Energy

PVDF (polyvinylidene fluoride) is a very well known material for converting mechanical energy into electrical energy and gold nanoparticle are versatile material for a broad range of applications with well characterized electronic and physical properties. In this work, we developed gold nanoparticle doped PVDF nanofiber based nanogenerators which are concurrently harvest light and mechanical energy into electrical energy. Here nanofiber has been made by electrospinning process. Characterization of fiber has been done by FE – SEM instrument , UV – VIS spectroscopy instrument and FTIR instrument. Beside this, characterization of film (Casted at 120 0 c) has also been done . For nanogenerator preparation ITO coated polyethylene terephthalate (PET) and silver fabric were used as electrodes. Finally polydimethylsiloxane (PDMS) were used for coating these nanogenerators. Electrical output data have taken in different combination of light and mechanical energy and calculated the damping ratio of these nanogenerators (before PDMS coating) in cantilever geometry. In future GO, RGO or Semiconductor quantum dots (QDs) can be incorporated into this nanofiber based nanogenerator for improvement of better optical ,electrical and/or electronic properties.
