TEHRAN -- Iranian researchers at Tarbiat Modarres University and Sharif University of Technology succeeded in the production of nanostructured titanium oxide coatings for photocatalytic applications through an economic method.

Nanostructured titanium oxide coatings were synthesized through electrophoretic deposition method which is a very cost-effect, simple, and applicable method. Studying the electrophoretic deposition process mechanism by using various solvents and selecting an appropriate solvent in order to create the coating was among other objectives of the research.

According to the researchers, one of the most important innovations of the research was to benefit from the effect of solvent type in the formation of suspension on the electrophoretic deposition process and on the coating properties.

Studies showed that the microstructures of nanostructured titanium oxide coatings made of butanolic suspensions that contained the optimum concentration of triethanolamine had the highest quality and were the most homogenous microstructure, and they resulted in high photocatalytic efficiency. Also about the electrophoretic deposition process it was found out that the additive could very much affect the stability of the suspension and electrical resistance of the deposit, and consequently, it could affect the rate of coating formation during the process and the microstructure of the coating as well.

Further investigations on the mechanisms of electrophoretic deposition process have been and are still being carried out by Eng. Farrokhirad and Dr. Taqi Shahrabi from Tarbiat Modarres University. They have observed interesting phenomena in regard with the mechanism and kinetic of electrophoretic deposition method.

About INIC

Iran has recognized the significance of nanotechnology like other pioneering countries and started its activities in line with development of the technology. In this regard and as first step, a Study Committee for Nanotechnology in Iran began its activities in 2001 and finally Iran Nanotechnology Initiative Council (INIC) was established in the country in 2003.

The INIC is tasked with determining the general policies for the development of nanotechnology in the country and pursuing the case with implementation of the policies. Iran's success in achieving a proper place among 15 countries which are advanced in nanotechnology and making attempt to promote the position in a bid to develop Iran's economy are the main missions of the INIC.

Iran Nanotechnology Initiative Council is seeking to pave the ground for activity of the private sector and production of wealth within the society through adopting outlook, providing facilities, creating market and removing the existing problems.
