Synthesis, Characterization and Electrical Conductivity of Poly Vinyl Alcohol Graft Adipic Acid and Application as Sensors

Author: SARA MURAD1, SAMAH HUSSEIN KADHIM
Abstract: DC conductivity of PVA-g-AA doped films including various Eosin B ratios (0.01, 0.03, 0.05, 0.07, 0.09, 0.12 and 0.15)% Wt in this study, are studied. Through casting techniques, the composite materials have been prepared. Thermogravimetric analysis (TGA), Fourier Transform Infrared Spectroscopy (FT-IR) and X ray diffraction (XRD) analysis have characterized the preparation of PVA-g-AA composites that found the formation of the composite and the adipic acid presence in polyvinyl alcohol. Studies of DC conductivity demonstrate all composites in thermally activated behavior. Conductance has been found to reduce with increasing temperature showing the semi-conductive behaviour for all doping ratios. With doping ratios in coloring and increasing temperature, the activation energy reduced. Maximum conductance in polyvinyl alcohol has been measured in 0.15% of dye. In sensor technology, Dye sensitization of performing polymeric materials had acquired practical application and wide theoretical interest. The current study provides the effect of polymer presence of dye (conductivity, structure and properties), dye sensitized photo sensors and application in sensors. At the end, advantages and perspectives were included of sensitizing polymers or modifying dye in sensors.
