PhD Thesis Defense by Alejandro Borrás "Graphene oxide composite aerogels fabricated by supercritical CO2 technology: characterization and applications"

Abstract:
This thesis is focused on the utilization of supercritical carbon dioxide (scCO2) for the fabrication of 3D graphene oxide mesoporous aerogels. This new methodology retains the oxygen functionalities present on the graphene oxide flakes during the process, allowing the interaction between the aerogel surface and other components through these oxygenated functional groups. Hybrid composites of graphene oxide and other materials have been fabricated utilizing: dense nanoparticles, polymers and MOFs.
These aerogels have been prepared and characterized via several solid state characterization techniques, while looking into potential applications, such as: gas adsorption and separation, water purification, magnetic resonance imaging, and energy.
