 tability and adsorption at interfaces - Tom McCoy\, BP Institute

DESCRIPTION:Two-dimensional carbon nanomaterials\, namely graphene oxide a
 nd reduced graphene oxide\, have gained enormous research momentum over th
 e past decade. Their water compatibility and second to none surface area m
 ake these materials promising in many industrial applications\, from water
  purification to oil recovery and more. The seminar will present recent wo
 rk on aqueous graphene oxide dispersions that utilises small surface activ
 e molecules (surfactants) to mediate the behaviour of these materials in s
 olution. The surfactant molecules are found to induce specific colloidal e
 ffects\, such as particle flocculation or adsorption at interfaces dependi
 ng on their chemical functionality\, giving fundamental insight into the k
 ey driving factors for efficient recovery or stabilisation of interfaces u
 sing two-dimensional carbon materials.
