“…Hierarchical rough structure and low surface energy are two critical factors for the superhydrophobic materials. 29 In order to construct superhydrophobic MS, a series of organic/inorganic nanoparticles which can increase the surface roughness such as SiO 2 , 30,31 CNTs (Carbon Nanotubes), 32 GO (Graphene Oxide), 33 Fe 3 O 4 , 34,35 and MXene (Ti 3 C 2 ) 36,37 were introduced onto the framework of MS through dipping, chemical vapor deposition, selfassembly methods and so on. For example, Huang et al 36 loaded MXene onto MS by dipping, resulting in a water contact angle (WCA) of 150 for Ti 3 C 2 T x @MS, which also has a high adsorption capacity and recycling performance.…”

Oily wastewater has caused serious damage to the human health and ecological environment. It is urgent to develop novel materials for high performance oil/water separation. Porous melamine sponges (MS) are considered as an ideal matrix material for oil/water separation. Herein, molybdenum sulfide (MoS2) modified with tannic acid (TA) and octadecylamine (ODA) was attached to MS framework via a facile dip‐coating method. This novel and eco‐friendly MS@(MoS2@ODA) sponge displays superior superhydrophobicity (WCA = 156.2°) and oil/water separation ability (absorption capacity = 113–145 g g−1). MoS2@ODA not only enhances surface roughness of MS framework, but also raises its specific surface area, causing an increase in the oil adsorption capacity of MS. Moreover, the composite sponge exhibited excellent chemical and mechanical stability. It is envisioned that this work can demonstrate a facile synthesis strategy for producing environmental friendliness MS with stable superhydrophobicity for high‐efficient oil/water separation.
