摘要:纳米纤维素表面富含活性羟基,具有高度的亲水性和吸水性,这在很大程度上成为影响纳米纤维素在工业上大规模应用的主要因素。对纳米纤维素表面的活性羟基进行化学修饰提高其疏水性,日益成为国内外学者研究的热点。本文在简要阐述超疏水材料基本特征和制备方法的基础上,对比了不同超疏水材料制备方法(模板法、喷涂法、沉积法、刻蚀法)的优劣,重点介绍了国内外学者利用纳米纤维素构建超疏水材料(气凝胶、纸张、涂层、薄膜等)在生物医学、造纸工业、油水分离、食品包装、储能材料等不同领域的研究进展,归纳并分析了目前纳米纤维素构建超疏水材料在改性方式和性能提升等方面仍存在的问题,同时指出了纳米纤维素构建超疏水材料未来将朝着过程无污染化、工艺简化、稳定性优化等方向发展。
Due to the abundant hydroxyl groups on the surface,nanocellulose has high hydrophilicity and water absorption,which has become the main factor affecting its large-scale application.Functional modification of the active hydroxyl groups on the surface of nanocellulose to improve its hydrophobicity has increasingly become an attractive research area.Based on a brief description of superhydrophobic materials and a comparison of different preparation methods of superhydrophobic materials,this article focused on the research progress on using nanocellulose to construct superhydrophobic materials(aerogels,paper,coatings and films)in the fields of biomedical,papermaking,oil-water separation,food packaging,energy storage materials,etc.,and summarized and analyzed the problems in the application of nanocellulose superhydrophobic materials.At the same time,it was pointed out that the future development direction of nanocellulose to construct superhydrophobic materials would focus on the pollution-free process,process simplification and stability optimization.
