Structural and optical investigations on ZnO-PVDF-NiO advanced polymer composites for modern electronic devices

Abstract Polymer composites are recently introduced as flexible candidates for modern electronic devices. Transition metals oxides incorporated PVDF polymer composite thin films were successfully synthesized and investigated an optical response. The effect of ZnO NiO nanoparticles fillers is studied in this work. Experimentally pure doped uniform evenly distributed by sol-gel based spin coating method. Structural studies carried out with x-ray diffraction analysis which reveals the sharp traces endorses presence crystalline films. Field emission scanning electron microscope was used to examine surface morphology prepared containing a smooth, distribution compact traces. Refractive index, extinction, absorption coefficient, reflectivity, conductivity real epsilon extracted using spectroscopic ellipsometry. Enhanced response parameters observed composites. coefficient seems increase increment nano-filler contents, makes these materials suitable photovoltaic applications. maxima refractive index recorded 1.6 2.1 maximum content incredible shift higher energy values. incorporation PVDF. values 2.3 3.9 highest composition. increasing trend nano-fillers compositions attributed enhanced polarization storage capability outcomes work considered that ZnO-PVDF-NiO advanced promising
