纤维素及纤维素纤维气凝胶的制备及其在油水分离中的应用研究进展OA

In recent years,researchers have prepared various adsorbent materials for oil spill treatment.Among them,aerogel,as the lightest synthetic solid on earth,has the advantages of ultra-low density,high porosity and high specific sur-face area,and has received a wide attention in oil-water separation treatment.As a cheap and abundant natural polymer,cellulose is a good raw material for preparation of aerogel materials.In this article we review preparation methods,drying methods and hydrophobic modification methods of cellulose aerogel,also analyse and summarize the application status of cellulose aerogel in oil-water separation field.
