Superwetting materials have showed promising potentials for oil/water separation and attracted great interests. The recent advances in oil/water separation technologies through filtration and absorption, particularly the separation materials based on low-cost and eco-friendly natural materials with surperwetting properties, are reviewed. For each material, such as sand, wood sheet, coconut shell, representative research works are introduced, and their preparation process, inherent or modified wettability, as well as the related oil/water separation applications are described. The separation mechanisms of oil/water mixtures, oil-in-water (O/W) emulsions and water-in-oil (W/O) emulsions with superhydrophilic/underwater superoleophobic and superhydrophobic/superoleophilic materials are reviewed and discussed. Finally, the challenges and future research directions of the field are prospected. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书附件1 -->
