Abstract

Tungsten organometallic sol and tungsten organometallic-PANi sol were deposited onto SiO2 coated silicon substrates by a sol-gel spin coating technique. SEM studies on tungsten organometallic film show that it consists of many hollows compared to tungsten organometallic doped 1 wt.% PANi while SEM studies on tungsten organometallic doped 4 wt.% PANi show the sample became porous and agglomerated. Tungsten organometallic sensor was responsive towards isopropanol vapour at room remperature with sensitivity of 13.03%. Although the sensitivity of tungsten organometallic-PANi is lower than undoped PANi sensor, the hybrid sensor exhibited good reversibility meanwhile response of undoped PANi sensor decrease extremely with time. The small amount of PANi doping into tungsten organometallic sol improved the sensing properties of the sensor in terms of reversibility and recovery time.
