Abstract
Two-dimensional carbon nanomaterials, namely graphene oxide and reduced graphene oxide, have gained enormous research momentum over the past decade. Their water compatibility and second to none surface area make these materials promising in many industrial applications, from water purification to oil recovery and more. The seminar will present recent work on aqueous graphene oxide dispersions that utilises small surface active molecules (surfactants) to mediate the behaviour of these materials in solution. The surfactant molecules are found to induce specific colloidal effects, such as particle flocculation or adsorption at interfaces depending on their chemical functionality, giving fundamental insight into the key driving factors for efficient recovery or stabilisation of interfaces using two-dimensional carbon materials.
