Sustainable Development Goals are an urgent call for peace and prosperity of the whole world. Among the 17 goals, goal 14, called as life below water, aims to conserve and sustainably use the oceans, seas and marine resources for sustainable development. Oceans, seas and coastal areas are extremely important part of the Earth's ecosystem. Therefore, it is extremely important to maintain the ecology and cleanliness of the oceans, seas and coastal areas. During the past few decades, there have been many oil spill accidents during extraction, transportation and storage of oil, which blackened the shoreline, threatening trees, killing large numbers of fishes and mammals . Therefore, a speedy clean-up is always required. To address this issue, this study adopted melamine as core material to prepare porous materials possessing superhydrophobic and superoleophilic property, which is utilized to eparate polar and non-polar solvents from polar/non-polar mixture. The sponges were treated by four different methods; (1) acetone treatment, (2) coating of functionalized expanded graphite (FEG), (3) coating of multi-walled carbon nanotubes (MWCNTs) and, (4) coating of reduced graphene oxide (rGO). Based on the experimental results, sponge treated with acetone showed the best absorption capacity, but worst hydrophobic property; while the sponges coated with FEG and MWCNTs possessed the worst absorption capacity. The sponge coated with reduced graphene oxide showed notable superhydrophobic property, as well as excellent absorption capacity. In this work, we also designed a set-up to separate organic solvents from organic-water mixture using the superhydrophobic and superoleophilic sponge.
