Anti-corrosive Graphene Coating Saves Money And Environment

A coating is applied to surfaces with decorative, functional or both purposes. One of the key features of coatings is to protect objects from such a serious global problem as corrosion.

Corrosion of material is caused by humidity, salt water, oxidation or other reactions with surrounding environment. It causes million dollars of loss in industry every year. It’s not a surprise that it has attracted many players as the coating market is growing from $14,276 million in 2015 to $26,627 million in 2022[1] . Big companies as 3M, AkzoNobel or PPG are constantly trying to bring innovative solutions for corrosion.




One of the materials that is predicted to solve the problem is Graphene. Graphene is well-known as the thinnest material for corrosion protection and while keeping it light weight it can significantly enhance properties of coatings.

In 2DM, we tested our graphene as a coating on steel, copper and aluminum. The results we achieved with our graphene were awesome. As 2DM has the know-how to produce the highest quality graphene in the world, the improvements of the coatings were significant.




You can find steel in the construction of railways, cars , planes, and buildings. You can see the results of our experiment with PDMS + Graphene coating on a mild steel on the picture above. 



Copper is widely used in electrical equipment such as wiring and motors as it conducts both heat and electricity very well, and can be drawn into wires. However, to make copper less corrosive is a real challenge. We tried our graphene as a coating on copper. The result: Graphene-coated copper surface exhibited 30 times higher corrosion resistance compared to neat copper. 


Aluminium is in a huge variety of products including cans, window frames, automotive and aeroplane parts. However, it is a more chemically reactive metal than iron. Our team of researchers tried to slow down corrosion of aluminium. The result: Corrosion resistance of aluminium increased nearly 3 times by applying graphene coating. 

Graphene enables a wide array of functional coatings for many possible applicantions and will play significant role in automotive, aerospace and marine industry. This is an easily scalable, environmentally friendly one-step process to slow down corrosion without needing to change processes.
