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

Abstract

TiO 2 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 TiO 2 . 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 TiO 2 thin films. The DC electrical conductivity was measured for the dip coated Camphor sulfonic acid protonated Poly (2, 5-dimethoxyaniline) /TiO 2 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) /TiO 2 blend thin film of 0.6 mol concentration shows higher DC electrical conductivity when compared to other mol concentration.
