Researchers from Monash University have discovered a greener method to produce high-performance graphene, which could cut down energy use and eliminate toxic by-products.
The researchers have developed a green, solvent-free method to produce nitrogen-doped graphene nanoplatelets using a bio-derived nitrogen source.
The new method uses mechanochemistry, which combines materials through grinding rather than chemical solvents.
The resulting material shows improved electrical, thermal and mechanical performance and even demonstrates electrically triggered self-healing when integrated into advanced polymer systems.
“This method proves that you can make advanced materials without compromising environmental responsibility,” said Chamalki Madhusha, a third-year PhD student in the Faculty of Engineering.
The breakthrough method could offer manufacturers greener production pathways for polymers and composites, reducing their chemical waste and energy costs.
Materials scientists and R&D teams could explore its use in smart coatings, electronics, sensors and self-healing systems.
While still experimental, the method shows how high-performance materials can be made without harming the environment.
