Oil-water separation is an effective way to solve oil pollution of water. Cellulose-based porous composite materials are widely used to separate oil and water, due to the characteristics such as special surface wettability, high adsorption, recyclability and low cost. In this article, the preparation methods for cellulosebased porous composite materials for oil-water separation, including electrostatic spinning, chemical crosslinking, solgel, freeze-drying, and 3D printing were reviewed. The methods of hydrophobic modification for cellulose-based porous composite materials, including high-temperature carbonization, chemical vapor deposition and surface coating were introduced, and the effects of different modification methods on the oil-water separation property were summarized. The existed problems of material preparation methods and modification methods were discussed, and the development direction of cellulose-based porous composite materials for oil-water separation was prospected.
