- Abstract
- We propose a hydrophobic graphene-sponge composite produced by embedding graphene flakes within polyurethane sponge as a selective absorbent for hydrophobic liquids from a contaminated water mixture. The self-aggregation nature of graphene flakes effectively allows higher graphene content to be added inside the polyurethane sponge with repeated dip-coating. High hydrophobicity due to the intrinsic nature graphene surface allows the selective absorption of liquid contaminants from a water mixture. Given the porous structure of the composite, absorption capability of 134-233 times its own weight towards various hydrophobic liquids is possible.
