Oleophobic composite films based on multi-layer graphitic scaffolding

A new oleophobic composite material synthesised by utilising plasma-exfoliated multi-layered graphitic (MLG) material as scaffolding is presented herein. The composite consisted of a polyelectrolyte/fluorosurfactant complex derived from polydiallyldimethylammonium chloride (PDDA) and sodium perfluorooctanoate (PFO) and was used to prepare free-standing MLG composite films. Free-standing films based on a plasma-exfoliated multi-layer graphitic material composite comprising polyelectrolyte and fluorosurfactant. Such materials show oleophobic/hydrophilic properties and application within oil-water separations.
