1. Investigating the Growth,
Characterisation and Corrosion
Resistance of Graphene on Metal Surfaces
Name: Adam Brown
Student Number: n8592276

2. Project Overview
• What is the feasibility of graphene as a
corrosion inhibiting barrier on copper?
• Can Graphene be used to coat other
metals such as stainless steel used for
medical applications?

3. Graphene Background
• A 2-dimensional hexagonal lattice of
carbon atoms
• Young’s Modulus > 1000 GPa
• High thermal and electrical
conductivity
• Flexibility and optical transmissibility

4. Project Objectives
• Growth
• Characterisation
• Corrosion Testing
• Re-characterisation
• Comparison

5. Graphene Growth

9. Conclusion
• Graphene coated copper has shown
higher resistance to corrosion when
compared to uncoated copper
• Recommend that testing on stainless
steel should progress
