Abstract:

Among one dimensional nanomaterials, TiO۲ nanorods have found important applications in various industries due to optical, photocatalyst and self-cleaning properties. In this research, at first TiO۲ nanorods were synthesized on a glass substrate by hydrothermal method. Then a thin film of TiO۲ particles was dip coated (as seed layer) on the substrate. After that, hydrothermal synthesis of TiO۲ nanorods with ۰.۰۵ and ۰.۱ mol concentrations was carried out on the seed layer. Morphology and microstructure of the seed layer and nanorods were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic force microscopy (AFM). Hydrophobicity of nanorods was studied by contact angle instrument. Results revealed that nanorods synthesized on the glass substrate without seed layer are not aligned at all and have the average diameter of ۱۲۰ nm, whereas nanorods synthesized on the seed layer are well-aligned with ۳۰nm average diameter. The result obtained from contact angle instrument showed that nanorods synthesized with ۰.۰۵mol concentration have larger contact angle (۱۵۷º), compared to those synthesized with ۰.۱mol concentration which have ۱۱۵º contact angle.
