Abstract

The research work mainly focusses on the preparation of nanogenerators based on PVDF/Cloisite-30B and PVDF/BaTiO3/Graphene polymer nano composites using electrospinning technique. The process parameters were designed and optimized by applying Taguchi's Design of Experiments with L4 array. Morphology of the polymer composites were studied using Scanning Electron Microscopic images. β-phase Crystallinity of PVDF/Cloisite-30B and PVDF/BaTiO3/Graphene was 85% and 80% respectively when it is estimated using FTIIR spectroscopic technique. The nanogenerator with PVDF/BaTiO3/Graphene produced 3.65 V and the same was 3.5 V in case of PVDF/Cloisite-30B nano composites. Better crystallinity was observed in PVDF/Cloisite-30B fiber mats but improved sensitivity of PVDF/BaTiO3/Graphene resulted in slight enhancement of output voltage. The result indicates the ability of polymer composites as nanogenerator for development of wearable self-powered electronic devices for smart sensing applications.
