深海采油、原油海运及内河运输经常造成漏油事件，造成大面积、大流域水体污染，严重威胁脆弱的海洋和内陆水系生态环境。目前处理溢油的方法主要为材料吸附，传统吸油材料吸油保油效率低且后续回油性差，大面积应用受到限制。鉴于木质纤维气凝胶巨大的比表面积和极高的孔隙率，项目拟通过LiCl/DMSO对木质纤维进行溶解处理、酯化疏水改性，并在此体系下将油性单体MMA/BA进行自由基聚合及MBA交联，制备出具有高比表面积、高吸油性能的木质纤维网络与亲油高分子网络半互穿结构的气凝胶试样。研究木质纤维在全溶体系下进行酯化改性和亲油高分子网络构建工艺技术、木质纤维气凝胶的吸附动力学、吸油与保油性能，掌握全溶体系下木质纤维气凝胶网络构建及性能调控方法，揭示木质纤维气凝胶吸油历程及规律，阐明木质纤维气凝胶的吸油与保油机理，为开发环境友好型高性能吸油材料提供理论依据。

Subsea oil exploitation, crude oil marine transportation, and inland canals transportation always caused the oil spill, which pollutes the large-area watershed and seriously threatens to the fragile marine and inland river eco-environment. The main approach to dealing with oil spill is absorbing by using some absorbents. The application of traditional oil absorbents is restricted by their low absorbing and keeping oil efficiency, and poor oil recovery ability after oil absorption. Considering the large specific area and high porosity of lignocellulose aerogel, it is proposed to dissolve the lignocellulose in LiCl/DMSO solution, then hydrophobic modify by esterification, and fabricate lignocellulose aerogel with high specific area and great oil-adsorption ability by semi-interpenetrating polymer networking of lignocellulose and oil-wet polymer which is composed of methyl methacrylate (MMA) and butyl acrylate (BA) in the presence of N,N-methylenebisacrylamide (MBA) as the crosslinker. In order to grasp the fabricating and performance regulating methods of lignocellulose aerogel, the esterification and polymer networking technology, the oil-adsorption kinetics of lignocellulose aerogel, as well as the oil-adsorption and retention performance will intensive studied in the lignocellulose solution system. Subsequently, the oil absorption process and regularity of lignocellulose aerogel are going to be in-depth reveled, and its oil absorption mechanism will be elucidated finally. All these work will make contribution to the theoretical foundation for the development of environmental friendly advanced oil absorption material.
