We have a decade-long experience in the development of cost-effective synthesis methods, of solution processed graphene and other 2D materials. This enabled the synthesis of high-quality inks and dispersions of conducting, semimetal, semiconducting and insulating 2D materials for high-performance electronics and photonics. The ink formulation is achieved by high-quality and high-yield liquid phase exfoliation process via ultrasonication and electrochemical exfoliation routes, to achieve a wide range of tunability of the morphology 2D and few-layer materials, while microfluidic exfoliation is used to process high volume and loading.

Schematic illustration of 2D materials exfoliation and ink formation. The nanomaterial inks can be used for the formation of thin film, fibre and fabrication of wearable electronic devices.

The functional 2D material inks are employed in a wide range of applications from the disposition of thin films via spray coating to printed electronics via inkjet printing as well as polymer composites for photonic applications. Our recent works have also extended the use of these 2D materials to the electronic fibres and textiles, for applications in flexible and wearable electronics.

The 2DWEB group has also an extensive experience in working with nanomaterials such as carbon and h-BN nanotubes as well as metallic nanowires for applications in printed electronics, polymer composites and photonics.

Examples of current ongoing projects include but are not limited to (1) graphene based printed electronics; (2) high-k dielectrics for printed electronics; (3) thermal transport of h-BN and MXenes; (4) MXenes used in perovskite solar cells.
