Monash University researchers have developed a green, solvent-free method to produce nitrogen-doped graphene nanoplatelets using a bio-derived nitrogen source.
Graphene is a single, two-dimension layer of carbon atoms arranged in a honeycomb lattice – making it the thinnest, lightest, and one of the strongest materials known while also being a conductor of electricity and heat.
The method uses mechanochemistry, which combines materials through grinding rather than chemical solvents, cutting down energy use and eliminating toxic precursors and by-products.
Monash University says the resulting material showed improved electrical, thermal and mechanical performance.
When included into advanced polymer systems, it shows electrically triggered self-healing, hinting at potential applications in smart, durable materials.
For manufacturers, the process suggests greener production pathways for polymers and composites, reducing chemical waste and energy costs. While still experimental, the method shows high-performance materials can be made without harming the environment.
A third-year PhD student in the Faculty of Engineering Chamalki Madhusha says this method proves that advanced materials can be made without compromising environmental responsibility.
