Superhydrophobic Graphene Aerogel as a New Oil Sorbent
New oil sorbents, superhydrophobic aerogels of reduced graphene oxide (rGO) and polytetrafluoroethylene (PTFE), were developed. The rGO/PTFE aerogels of 2 : 3, 1 : 1, and 3 : 2 compositions were prepared as granules and blocks with contact angles larger than 160°. The rGO/PTFE (2 : 3) granules and the block of the same composition exhibit the highest sorption capacity for crude oil: 26 and 58.5 g/g, respectively. A procedure was suggested for utilization of the oil-loaded aerogels by distillation of low-boiling fractions and pressing of the aerogel to obtain a hydrophobic additive to asphalt concrete mixtures.
