One-Dimensional TiO₂ Nanothorn-Like Structures Assisted TiO₂ Template for High Absorption Hydrophilic Self-Cleaning

Abstract:

One-dimensional (1D) titanium dioxide (TiO2) was synthesized using heat sol-dispersion immersion technique which is combination of four methods at lower temperature processing. The method is versatile with adjustable temperature, multi-ratio solution compositional and ability to tailor the structure into nanometer scale and small dimension of nanostructures. 1D TiO2 nanothorn-like structures assisted TiO2 template has been increased the performance of self-cleaning property with height of TiO2 nanostructures grew 17.5 nm at temperature 100oC. Further enhancing current work of coating function ability to the high performance and efficiency self-cleaning compared to present coating. The results showed a surface area for hydrophilic self-cleaning is 13.50 nm2 while the efficiency of 1D TiO2 nanostructures for self-cleaning through contact angle (CA) measurement indicated that 0.35 degrees after 2.30 minutes exposed to the water molecules droplets. The average of absorption coefficient (α) in UV region attribute 5.45 compared to another three heat immersions temperature.
