Purpose: In this project, the formulation of TiO2.Fe2O3 nanopaint was discussed. Design/methodology/approach: The paint was formulated in alkyd resin using ball milling process. Intermolecular bonding between TiO2.Fe2O3 and the alkyd resin was studied by Fourier transform infrared spectroscopy. The water contact angle was measured and it is found to be hydrophilic in nature. The prepared TiO2.Fe2O3 nanopaint disclosed good corrosion-resistant behaviour in acid treatment test. The inhibition efficiency was calculated to ensure the anticorrosive behaviour of paints. Findings: The recorded results reveal that, TiO2.Fe2O3 nanopaint has moderate solid content and mechanically low irregularities compared with bare steel. Corrosion resistance is high in nanoformulated paints and therefore it has high inhibition efficiency. The contact angle reveals the film is hydrophilic in nature which enhance the spreading rate of paints. Research limitations/implications: The method is not limited to TiO2.Fe2O3 nanopaint but is also suitable for the preparation of other nanomaterial-based paint. Originality/value: In this project, iron oxide and titanium oxide act as the corrosion inhibiting pigment.
