▎ 摘  要

In this work, we illustrate a facile and economical strategy for the bulk production of aqueous few layer graphene (FLG) dispersions via a simple grinding method. The as-prepared FLG suspensions can be cast on various substrates through facile dip coating. The environmentally friendly one-step procedure can produce graphene-based surfaces easily without additional reduction reaction. Here, we also prepare the FLG-based sponges with both superhydrophobic and superoleophilic properties. The FLG-sponges have been demonstrated as efficient absorbents for a broad range of oils and organic chemicals with high selectivity and excellent recyclability. The FLG-sponges deliver an absorption capacity as high as 153 g g(-1) for the chloroform. The results indicate that the FLG sponges may potentially be useful as next-generation oil adsorbent materials.
