Dr. Rawa Abbas Mohammed and Prof. Dr. Khulood Abdul Saleh from the department of chemistry at the college of science, have obtained a patent for their joint study entitled “Preparation of conductive polymers and nanocomposites from amic acid derivatives grafted with graphene oxide and zinc oxide nanoparticles on the surface of carbon steel in a saline medium as anti-corrosion and antibacterial coatings” after completing all the requirements needed for being approved by the Central Organization For Standardization And Control Quality.
The patent aimed to shed light on corrosion process which is of paramount importance to researchers around the world, given its catastrophic impact on both the economy and people’s safety since new strategies stress on using new materials to reduce corrosion. These two professors stated that nanocomposites are based on conductive polymers that have shown promising results for the corrosion protection. They also concluded that polymers can be prepared by electrochemical polymerization method before and after the addition of nanomaterials that have been characterized with their high efficiency due to their unique composition containing (π-bonds) where the persistent electrons contribute to the polymerization process and leading in this case to an inhibition. It is noteworthy that these polymers are characterized by high efficiency, low cost, ease of preparation, where the results showed that the coating leads to an increase in the life of the alloy (carbon steel) coated with polymeric layers and reduces losses, due to the decrease of corrosion and reducing the percentage of contamination with metal ions of the industrial product.
