Synthesis and Effect of TIO2 on Electrical Conductivity of Poly (2, 5-Dimethoxyaniline)/ TIO2 Thin Film

Abstract

TiO2 has been synthesized using Titanium isopropoxide as precursor solution. Different amount of Titanium isopropoxide of 0.2, 0.4, 0.6, 0.8 and 1 mol concentration used to synthesis TiO2 . Different mol concentration solution has been blend with Camphor sulfonic acid protonated Poly (2, 5-dimethoxyaniline) and cast as thin film by dip coating. The optical and XRD analyses were carried out for the dip coated TiO2 thin films. The DC electrical conductivity was measured for the dip coated Camphor sulfonic acid protonated Poly (2, 5-dimethoxyaniline) /TiO2 blend thin films. The Titanium isopropoxide of 0.6 mol concentration shows better UV-Vis absorption and crystalline nature. Camphor sulfonic acid protonated Poly (2, 5-dimethoxyaniline) /TiO2 blend thin film of 0.6 mol concentration shows higher DC electrical conductivity when compared to other mol concentration.
