Polylaniline (PANi)-TiO2 composites have been applied as corrosion-resistant coatings in ferrous metals in this study. TiO2 used in this PANi-TiO2 composite there are four variations, namely commercial TiO2-anatase, commercial TiO2-rutile, synthesis TiO2-anatase, and synthesis TiO2-rutile. The composition of TiO2 in the composite is 30 wt.%. The composite superimposed on ferrous metals by dip coating method with a 30-second dipping time. Corrosion testing was performed using a salt spray chamber with 5% NaCl to representing atmospheric conditions. Samples were observed every 10 hours for 80 hours. Based on the results obtained, the PANi-TiO2 composite with commercial TiO2 rutile is the best composite type as corrosion coating material in this study with a corrosion rate of 10.20 mpy or a corrosion rate decrease of up to 90% when compared with ferrous metals without coating.
