摘要：
A novel recyclable, superhydrophobic and superoleophilic graphene-based textile sorbent was prepared for the removal of oil spills and organic pollutants, by functionalizing cotton mesh gauze with reduced graphene oxide (RGO) using dip-coating and hydrothermal reduction approach. The RGO-gauze composite textile showed efficient water/oil separation, and the amount of oil absorbed by the sorbent could be up to 11 times of its own weight. About 50(+/- 5)% absorbed oil could be recycled by mechanical squeezing and it was mainly extracted from the reserve of large-diameter capillary action. The RGO-gauze maintained high structural stability and outstanding recyclability after eight cycles of oil removal. This RGO-gauze consumes a small quantity of graphene (0.6 g m(-2)) and can be produced in large scale, very suitable for application in the cleanup of oil spill and organic solvent effluent.
