The CSIR’s Centre for Nanostructures and Advanced Materials (CeNAM) has developed a graphene synthesis technology platform that is cost-effective and accessible to local businesses. This platform stands out in terms of affordability when compared to the typical international market prices.

Graphene, recognised as an advanced material, holds significant relevance across various industries, such as composites, electronics, biomedical and healthcare, batteries, as well as in advanced materials, due to its substantial impact and versatile applications.

“In 2019, CeNAM embarked on the journey of local graphene production, investing significant efforts in refining the process due to the distinctive physico-chemical properties of graphene. Recognising the challenges posed by the exorbitant international graphene market prices, the CSIR leveraged its extensive nanotechnology capabilities to develop a cost-effective graphene technology,” says Dr Mike Masukume, CSIR principal researcher.

He adds, “Our graphene synthesis technology is based on a modified and improved version of Hummer’s method, enabling the production of high-quality and cost-effective graphene materials. We were able to successfully optimise this process and demonstrate a heightened technology readiness level, achieving a production scale of 1 kg per batch. This resulted in the production of two primary products: graphene oxide and reduced graphene oxide.”

This technology is ready for commercialisation, making it accessible to industries seeking to enhance their competitiveness by innovating new products or enhancing the properties of their existing products.
