Abstract

Development of organic and inorganic composites has grown in recent years due to a wide range of potential use of these materials. The aim of this research is to investigate the effect of Pani additions on the TiO 2 based thin film as VOC gas sensing properties. TiO 2 were prepared using sol gel technique. Up to 3wt% of Pani were directly added to the TiO 2 solution. 3 layers of TiO 2/Pani solution mixture were deposited onto SiO 2 coated silicon substrate using spin coating technique for fabrications of gas sensing device. The microstructures properties of samples were investigated using XRD, TEM and SEM. In addition, all samples were exposed to ethanol for gas sensing performance test. The gas sensing test revealed that all films were responsive towards ethanol vapour exposure with 2wt% TiO 2/Pani film exhibited the best sensitivity. However, over longer exposure cycles, it was observed that 3wt% TiO 2/Pani film have a better stability.
