Preparation and characterization of the hydrophilic nanocomposite coating based on epoxy resin and titanate on the glass substrate.
The hydrophilic organic-inorganic nanocomposite hybrid coatings were prepared using Tetrabutyl titanate. A simple sol-gel method has been developed for the preparation of nanocomposite coatings, at a molecular level and providing suitable conditions to obtain a complete conversion. The films were prepared on the glass substrates by dip-coating from a sol containing alcoholic tetrabutyl titanate which after the curing treatment, the gel forms a stable thin homogeneous nanocomposite coating. The obtained films were transparent to visible light and their surface hydrophilicity values were increased by increasing titania content in the water damp permeable self leveling flooring system. Characterization of the nanocomposite coating were performed by Transmission electron microscopy (TEM), Atomic force microscopy (AFM) analysis and contact angle test for water on TiO2 films that gave evidence of a strong interaction between the organic and inorganic phase with the formation of titania domains in the nanoscale range.
