Presentation Title Tunable Surface Wettability and Adhesivity of Nitrogen-doped Graphene Foam

On-Site Speaker (Planned) Shien Ping Feng
Abstract Scope We present an environment-friendly method involving water vapor treatment for achieving a highly hydrophobic and oleophilic NGF (CA ≈ 147.5°) for the efficient removal of oil from oil/water emulsions. NGF with high N doping content (N/C atomic ratio: 9.32%) was freeze-dried and annealed in a N2 atmosphere. Our results show that pyrrole acts as a combustible additive and reacts with surface-adsorbed oxygen during the annealing process, which causes localized surface burning, resulting in the formation of nanoholes on NGF surface. ATR-FTIR results implied that N functional groups at the edge of NG sheets promote interaction between bonded carbon atoms and water vapor, leading to the formation of a hydrocarbon layer that rendered the hydrophobic surface and tunable adhesivity. The achievement of tunable surface wettability and adhesivity of NGF by subjecting NGF to a water vapor treatment indicates that the NGF has considerable potential for other applications, such as water harvesting.
