Description
- Abstract:
- The successful application of new materials requires good understanding of their basic properties which govern their behaviors during manufacturing, processing, storage and disposal. Graphene based materials as an emerging family of carbon materials with promising mechanical, electrical and thermal properties have been believed to be “game changer” materials. Among these materials, the most promising category for large-scale production and application in industry are graphene oxide based materials, but some of their properties are still not well understood. Here this thesis focuses on investigating the chemical and thermochemical properties of graphene oxide based materials with both experimental and theoretical approaches. These properties are found closely related to materials chemical structures, more specifically the functional groups of the materials at the molecular level. For example, the conjugated π domain determines their capability to scavenge free radicals; the hydroxyl and carboxyl groups determine the dispersibility in aqueous or polar solvents; the epoxy groups determine the exothermic nature of the graphene oxide pyrolysis; the carbon backbone determines the reducing capability at high temperature. With the knowledge learned in this study, their implications for safe processing and storage were investigated using numeric simulations. New potential applications like oxidation protection using the antioxidant properties of the π conjugated domain and multifunctional platform for theranostics or pollutant cleanup using a couple of the unique properties of graphene oxide have been proposed and explored.
