Graphene, a two-dimensional form of carbon with extraordinary properties, represents the ultimate materials science frontier. One-atom-thick layers of carbon atoms arranged in hexagonal lattice, graphene possesses exceptional mechanical strength 200 times stronger than steel, superior electrical conductivity allowing current flow with minimal resistance, complete impermeability to most substances, and at exploitable projected costs under $100 per gram within 2 to 3 years — initial production runs show promising results for corrosion-resistance applications.
Indian research institutions are making genuine breakthroughs. IIT Bombay has developed in-house graphene synthesis methods using thermal exfoliation and chemical processing. Costs are declining toward commercial viability. Laboratory systems produce tiny quantities at enormous cost — graphene methods produce tiny quantities at enormous cost with $10,000 per gram costs — industrial-scale production requires fundamentally different approaches and equipment.
The envisioned application — graphene-enhanced barrier coatings for high-value infrastructure. A graphene-enhanced coating protecting a bridge structure could reduce corrosion maintenance by 50 percent over the structure’s 30-year lifespan. Coatings incorporating it into coating matrices produce stable dispersions, validating anti-corrosive performance through extended testing, achieving cost targets competitive with traditional coatings.
