The nanocomposites of PVDF/FLG and PVDF/GO are prepared using the solution casting method for varying concentrations of FLG and GO from 0.1 to 1 wt% in PVDF matrix. The effect and dispersion of FLG and GO are observed with help of Scanning electron microscopy (SEM) and x-ray diffraction confirming the good dispersion of FLG and GO in the matrix. The samples are also characterized for thermal and mechanical properties using Differential scanning calorimetry (DSC) and universal testing machine (UTM). FLG and GO nanofillers seemed to increase the tensile strength from 10 MPa to 20 MPa and variation in crystallinity to get maximum output in terms of β phase which can be utilized for piezoelectric and pyroelectric behavior of PVDF polymer.
