Abstract Details

2016, Doctor of Philosophy, Case Western Reserve University, Macromolecular Science and Engineering.
Graphene, a two-dimensional, one atom thick nanocarbon, has attracted tremendous attention for its excellent structural, chemical, mechanical, thermal, electrical and even biomedical properties. This dissertation aims to further enrich the growing body of knowledge on the different applications of graphene and derivatives as a multi-functional material. It highlights their rich chemistry and potential as a catalyst support, nanocomposite coatings, transistor materials, antibacterial agent and biocompatible nanocomposite hydrogels. Herein, a facile photoreduction technique of graphene oxide (GO) using ketyl radicals is demonstrated as a promising technique for plastic electronics application. Using the same chemistry, Ag, Au and Pd graphene-nanoparticle hybrids were also synthesized for the catalytic degradation of model environmental pollutants. The selective electrodeposition of GO by covalently linked electro-active monomer, carbazole (Cbz) as well as the anti-corrosion properties of GO-Cbz nanocomposites is also explored. The concept of electropolymerization-electrodeposition was then extended for the fabrication of graphene nanomesh (GNM) by using the colloidally templated conjugated polymer network as a mask for electrochemical oxidative etching of graphene. Moreover, Langmuir-Blodgett (LB) technique was used to immobilize flat GO sheets to shed light on the fundamental mechanism of the antibacterial activity of GO. Findings suggest that contact to the edges is not an integral part of the mechanism. Lastly, the preparation and interesting rheological behavior of covalently and non-covalently grafted GO-PEGMEMA nanocomposite hydrogels are also demonstrated.
