TEHRAN, Iran—Researchers in Iran are undertaking work to improve the anticorrosive properties of polymeric coatings. A team at the Institute for Color Science and Technology (ICST) is using graphene to create nanocomposite structures in its efforts to achieve these advancements, the Iran Nanotechnology Initiative Council (INIC) has reported. Affiliated with Iran’s Ministry of Science, Research, and Technology, ICST was founded to develop knowledge and technologies in all areas related to color, colorants, paint, and coatings.

Globally, countries spend a large amount of money on corrosion prevention and repairing the damages due to corrosion on an annual basis. Anticorrosive coatings are widely selected to reduce those costs. ICST researchers are using graphene oxide nanoparticles to create nanocomposite structures meant to increase the protective properties of epoxy-based anticorrosive coatings.

While the unique properties of graphene oxide-based nanoparticles have been getting a lot of research attention, these materials are not compatible or stable in most organic solvents. Therefore, surface modification using amine compounds is necessary. The nanosheets help to prevent the diffusion of corrosive agents into the coating or at least postpone the diffusion. Therefore, the life of the coating increases significantly.

The use of synthetic nanocomposite coatings for onshore structures, equipment, and petrochemical units reduces corrosion-related expenses and increases the life of equipment, including pipelines. Results of the ICST team’s research have been published in “Corrosion Science.
