IIT Guwahati Develops Advanced Epoxy Coating for Marine Steel Protection
Scientists at IIT Guwahati have created a special protective layer for steel that helps it last longer in salty water.
This layer is made by mixing tiny materials like graphene and zinc with a type of plastic.
The new coating works better than regular ones because it sticks tightly to the steel and keeps out the things that cause rust.
This is important for things like bridges and ships that are always in the ocean.
The scientists are still testing it in the lab to make sure it works well for a long time before it can be used in real life.
IIT Guwahati researchers developed a corrosion-resistant epoxy coating for steel structures in seawater.
The coating combines reduced graphene oxide (RGO), zinc oxide (ZnO), and polyaniline (PANI) for enhanced protection.
The nanocomposite forms a denser barrier, improves adhesion, and slows down corrosive elements more effectively.
The coating is suitable for marine infrastructure, offshore platforms, shipbuilding, and coastal pipelines.
The research is currently in the laboratory stage and requires further validation before commercial use.
