摘　　要：纳米纤维素作为一种性能优越的可再生纳米材料,应用前景极为广阔。然而,由于纳米纤维素结构上富含羟基,使其具有极强的亲水性,严重影响了纳米纤维素的疏水性能,并且在一定程度上限制了其在复合材料领域的应用。综述了纳米纤维素疏水改性的研究进展,从物理吸附、表面化学修饰(甲硅烷化、烷酰化、酯化等)、聚合物接枝共聚3个方面简述了目前应用较为广泛的疏水化改性方法,并对疏水纳米纤维素在包装材料、造纸、水净化等方面的应用现状进行了总结。最后对疏水改性纳米纤维素的未来发展进行了展望,旨在为疏水纳米纤维素的研究和应用提供参考。As a renewable nanomaterial,nanocellulose displays excellent performances and exhibits wide application potentials.However,nanocellulose has extremely strong hydrophilicity due to its abundant hydroxyl groups.Thus,the above characteristics not only seriously affect the performance of nanocellulose in terms of hydrophobicity,but also limit its applications in the field of composite materials to a certain extent.This article summarized the research advances of hydrophobic modification of nanocellulose in three aspects:physical adsorption,surface chemical modification(silylation,alkanoylation,esterification,etc.),and polymer graft copolymerization.Current wide applications of hydrophobic nanocellulose were also summarized in fields of packaging materials,papermaking,and water purification.At the end of this paper,the future development of hydrophobically modified nanocellulose was prospected,aiming to provide reference for the research and wide application of hydrophobic nanocellulose.
