“…TiO 2 has been used for environmental remediation purposes such as purification of water and air and also for solar water splitting. 1,2 A variety of techniques have been employed to deposit TiO 2 thin films on different substrates. Among all used methods, sol-gel is one of the most important techniques due to its low working temperature, high uniformity and purity of the final product and the ability of fabricating ceramics and glasses with new compositions.…”

In this work, titanium dioxide was coated on a metallic substrate using sol electrophoretic technique. Titanium dioxide particles were synthesised by hydrolysis and condensation of a precursor in a colloidal solution. The particles were suspended in the solution using electrostatic [hydrochloric acid (HCl)], steric [polyvinyl butyral (PVB)] and electrosteric [polyethyleneimine (PEI)] stabilisers and were coated on an electrode using an external direct electrical field. The pH, conduction and stability of the suspensions, deposition rate and the current versus time changes were monitored for suspensions containing different stabilisers. Low surface potential of the steric stabilisation and low conduction of the solution led to no film formation for solutions containing PVB. The highest zeta potential was achieved by addition of PEI as the stabiliser. The optimum applied voltage for pure, uniform and crack free titanium dioxide films was 6 V for suspensions containing PEI and 3 V for those containing HCl.
