IIT Guwahati Develops Corrosion-Resistant Epoxy Coating
Scientists at IIT Guwahati have created a special protective layer for steel.
This layer is made by mixing tiny particles of three different materials: reduced graphene oxide, zinc oxide, and polyaniline.
This mixture is then added to a type of paint called epoxy.
The new coating is better at protecting steel from rust, especially in places like the ocean where saltwater can cause a lot of damage.
The researchers tested the coating and found it forms a stronger, more even layer that sticks well to the steel and keeps out harmful elements.
This could be very useful for things like ships, oil platforms, and pipelines that are always in contact with saltwater.
The scientists are now working on testing how well it works over a long time and its impact on the environment.
IIT Guwahati researchers developed a corrosion-resistant epoxy coating for steel structures.
The coating combines reduced graphene oxide (RGO), zinc oxide (ZnO), and polyaniline (PANI).
It forms a denser and more uniform barrier, improving adhesion and corrosion resistance.
The coating is suitable for marine infrastructure, offshore platforms, and coastal pipelines.
Researchers are working on assessing the long-term durability and real-world performance of the coating.
