Graphene-based thin films

Graphene, graphene oxide, and other graphene-like materials have been the subject of intense research recently. Graphene became famous overnight when the Nobel Prize in physics was awarded to Novoselov and Geim in 2008. Graphene, the new wonder material, has the highest thermal and electrical conductivity, highest tensile strength, largest Young’s modulus, and a plethora of other remarkable properties that make it deserving of so much attention. Our research group focuses on the synthesis of the material in the bulk phase (powdered form) from various carbon sources as well as finding applications for this form of the material.

Recently, our work has focused on conductive thin films both on solid and flexible substrates that enable electronic applications such as touch screens and organic photovoltaics, as well as wearable strain and humidity sensors. Future work will focus on supercapacitive and photocatalytic nanocomposites from TiO2 and WO3 nanoparticles for energy storage and water decontamination applications.
