Influence of N-Doped TiO₂ Nanocomposite Film on Hydrophilic Property of Rubber Dipping Former Surface

Abstract:

The objective of this study is to explore a method to improve hydrophilicity of the surface of formers that could be more easily dipped to produce high quality dipped rubber products. Photocatalytic TiO₂ composite films were prepared by sol-gel method. Glass formers were coated with nitrogen doped TiO₂ nanocomposite film by dipping method and annealed at 600°C for 1 h. Phase formation of TiO₂ was characterized by XRD. Morphology of the TiO₂ films was observed by using atomic force microscopy (AFM). Optical absorption of the films and degradation concentration of methylene blue had been measured employing UV-Vis spectrophotometer. The hydrophilicity of the thin films was determined in terms of the contact angles of water and NR rubber latex droplets on the coated TiO₂ composite films under visible light irradiation. It was found from the experimental study that the TiO₂ nano-composite film can improve wet-ability of the coated former surfaces.
