Green Fabrication of Nio Nano Particles Doped PS-PVDF Nanocomposite Films: Structural, Morphology and Electrical Studies

Abstract

Solution cast polymerization scheme was used to create PS-PVDF/Nickel oxide (NiO) hybrid nanostructures (NSs) utilizing Nickel nitrate as a metal precursor, PS-PVDF as a polymerizing agent, and Aloe-Vera (A.V.) gel as an organic fuel. In contrast to the unadulterated segments, PS-PVDF and NiO nanoparticles (NPs), due to communication among the PS-PVDF and the NiO NPs, the electrical investigations of PS-PVDF/ NiO hybrid NCs are rather distinct. Dielectric behavior is observed that NCs with dopant of 40 wt.% NiO shows maximum dielectric constant compared with the rest of the composites and at the relaxation point, dielectric loss and the conductivity increases which correspond to fall in the dielectric constant. The results of the gas sensing investigations show that the constructed NCs have an excellent reaction to gas leaking. As the NiO NPs concentration increases from 10% to 50% wt%, AC and DC conductivity in the hybrid NCs increases from 1 x10-5 to 5 x 10-5 (S/cm)-1 at ambient temperature. The presented sensor system exhibits lower noise, higher resolution and higher sensitivity than electrochemical sensors previously used. PS-PVDF/ NiO NCs sample based on the results of the measurements and data collected, the synthesized hybrid NCs might be employed in optoelectronic device applications and it’s a semiconducting material.
