Abstract:
Oil leakage and discharge of organic wastewater have not only threatened the ecosystem, but also greatly aggravated water scarcity. Efficient separation of oil-water mixture has become a global challenge. To solve this issue, various hydrophobic membranes with special wettability have been developed in past decades. Among them, the hydrophobic silicone-modified membranes have attracted much attention due to their low cost, easy processing and large-scale production. Herein, recent progresses of hydrophobic silicone-modified membranes for oil-water separation are reviewed. Basic mechanisms and principles for efficient oil-water separation are presented as a starting point for the discussion. Then, according to the modified silicone polymers or molecules, we give a detail description of their synthesis and briefly introduce the main reactions with the substrate, the typical grafting strategy and fabricating methods. Subsequently, the performance and oil-water application of various hydrophobic membranes modified silicone are introduced. Finally, some problems and challenges faced by silicone modification are summarized and present, and their future development is also prospected.
