Flexible sensors based on laser induced graphene

Abstract

Graphene has become an important topic in materials sciences over the past decade because its remarkable physical properties are often related to the presence of Dirac fermions in its band structure. However, real-world graphene-based technologies still have a long path to reach the technological matureness necessary for commercialization as graphene processing techniques are usually not scalable or do not yield high-quality materials. In this context, laser-induced graphene (LIG) has an enormous potential to become the major technological path to realizing graphene-based materials and devices in different contexts. LIG can be depicted as a 3D porous form of graphene formed due to the localized thermal effect that CO2 lasers may have on carbon-rich surfaces. Most studies on LIG-based materials explore fabrication techniques in which LIG is produced by lasing commercial films of polyimide. In recent years there has been an ongoing growth of interest to examine the potential of LIG in both academic and commercial applications. This research proposal aims to develop and characterize LIG-based nanocomposites by combining this 3D form of porous graphene with other nanostructured materials, such as semiconductor metal oxides (SMOx), metallic nanoparticles (NPm), and layered transition metal dichalcogenides (TMDs). Furthermore, the materials developed during this project will be used as resistive and electrochemical sensors to explore their potentialities in sensing applications, including detecting chemical and biochemical species.
