Asia and the Middle East two of the fastest-growing markets for advanced materials and graphene-based solutions

When incorporated into coatings, graphene creates a dense, impermeable layer that prevents the ingress of water, oxygen, and other corrosive agents to the underlying substrate, notes Ms Valdirene Peressinotto, Executive Director, Gerdau Graphene, in a chat with C&ACER

What is graphene and why is there so much buzz around it?

Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, forming a two-dimensional structure. Despite its minimal thickness, it is approximately 200 times stronger than steel and exhibits exceptional performance enhancements including anti-corrosive properties, electrical and thermal conductivity, flexibility, and transparency. These unique properties make graphene a revolutionary material with potential applications across various industries, including electronics, energy storage, composites, and coatings. The excitement surrounding graphene stems from its potential to transform these sectors by enhancing product performance and enabling new technological advancements.

How does graphene help with corrosion management?

Graphene's exceptional barrier properties make it highly effective in corrosion management. When incorporated into coatings, graphene creates a dense, impermeable layer that prevents the ingress of water, oxygen, and other corrosive agents to the underlying substrate. This barrier significantly reduces the rate of corrosion, thereby extending the lifespan of metal structures and components. Industries such as marine, automotive, and infrastructure benefit from graphene-enhanced coatings that offer superior protection against environmental degradation.

Can graphene improve the performance of paints and coatings?

Absolutely. Graphene serves as a multifunctional additive in paints and coatings, enhancing several key performance attributes:

Durability and abrasion resistance: Graphene's strength improves the wear resistance of coatings, leading to longer-lasting surfaces that withstand mechanical stresses.
