In this research, the effects of organic‐inorganic hybrid nanocomposites as novel nanostructure additives in paint compositions were studied. The silica modified TiO2 nano structure was prepared by using sol–gel method. The TEM analysis indicated that these particles were in the range 10–15 nm. The organo silicone containing polymer was prepared by free radical polymerization process. The prepared polymer/mixed metal oxides nanocomposites were fabricated and demonstrated as nanostructure additives. The prepared nanocomposite was introduced into the road marking material formulation. In the first part of the current study, the prepared samples were evaluated by quality control experiment such as compatibility and color visualization tests. Also specific experiments such as hydrophobicity, adhesion, exposure to weathering conditions, self‐cleaning nature of the samples, gloss appearance, hardness of the prepared samples, anti‐pollution investigation, moisture resistance, and heat‐cold cycle's tests were evaluated. The environmental issue of the road marking material and also the dirtiness removal efficiency by using nanostructure coating was investigated. The prepared samples showed 4–7 mg weight loss per hundred square centimeters during the exposure to 300 h by 313 nm UVB irradiation. The best photocatalytic performance in road marking application was found for NA 3% sample.
