Abstract
Titanium - polyaniline nanocomposites were prepared using polymerization of aniline. Structure (XRD), surface (SEM, AFM), chemical (FTIR) and optical (UVSpectrophotometer) properties have been examined. The X-ray diffraction pattern observed the PANI/TiO2 has a crystalline nature and the peak intensity increases with TiO2 composition ratio, the results of SEM &AFM images show the surface of TiO2- polyaniline have regular distribution and homogeneous structure. Furthermore, the grain size increases with increasing of TiO2 compositions and was found to be 32.58nm, 36.21nm and 47.67 nm at x= 0.2, 0.5 and 0.8 respectively. Additionally, optical properties show that the absorption intensity increases with TiO2 compositions compared to pure TiO2. Hybrid of TiO2/PANI has a vast attracted attention especially to improve photocatalytic activity. Simple design and high quality of nanocomposites play a crucial role in improving mechanical and physical properties.
