This study investigates the plasma surface modified spin coated PVDF-TrFE (70/30) film of 200nm thick using Atomic Force Microscopy (AFM), Water Contact Angle (WCA) and Fourier Transform Infrared Spectroscopy (FTIR). The surfaces of the spin coated PVDF-TrFE film were modified using 13.56 MHz...
XRD and FTIR measurements confirmed the presence of electroactive β-phase of PVDF in the composite samples. The DC conductivity at room temperature was found to increase with the increase in filler volume due CRediT authorship contribution statement Sushmita Dwivedi: Writing – original draft, ...
The polymer films ( PVDF and P(VDF-TrFE)) with different percentage of additives were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy ( FTIR ), thermogravimetry (TG), differential scanning calorimetry (DSC), and dynamical-mechanical analysis (DMA). The...
The influence of Fe concentration (x = 0.01, 0.03 and 0.05) made no significant change in the crystalline 尾-phase of the composite films as confirmed from XRD, FTIR and DSC studies. Maximum enhancement in the dielectric and ferroelectric behaviour was observed for the composite films with x ...
The films were structurally characterized through Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction, density, melt flow index, hardness, and thermal conductivity. The results showed that the polymers do not interact chemically with the additives leading...

microwave frequencyThe solution-based casting method fabricates the free-standing pure PVDF-TrFE, PVDF-TrFE-Nafion blended films and tests them for structural, morphological, and microwave studies. The X-ray diffraction pattern and FTIR spectrum confirmed the formation of the ferroelectric beta-phase ...
The ATR-FTIR for both single layer and bilayer nanocomposites films showed three distinguished peaks at absorption bands of 1400, 1290 and 848 cm, evident of the β-phase PVDF-TrFE crystals. The resistivity value recorded for the bilayer PVDF-TrFE/ZnO nanocomposites thin films were significantly ...
