摘要
着重综述了多形态纤维素材料(滤纸、棉织物、高分子膜、纤维泡沫和气凝胶等)疏水改性的研究进展,特别是改性方法,如喷涂法、浸渍法、等离子体法、化学气相沉积法、溶胶-凝胶法、原子转移自由基聚合(ATRP)、"硫醇-烯"点击反应等,进而阐述了纤维素基超疏水材料在防水防冰、阻燃和油水分离等领域的应用研究进展,最后对纤维素基材料疏水改性面临的问题进行了总结并展望了其发展前景.
Abstract
The research progress on hydrophobic modification of polymorphic cellulose materials(such as filter paper,cotton fabric,polymer film,fiber foams,and aerogels,etc.)was comprehensively reviewed,with particular emphasis on modification methods including spraying method,impregnation method,plasma method,chemical vapor deposition method,sol-gel method,atom transfer radical polymerization,"thiol-ene"click reaction,etc.Furthermore,the application research progress of cellulose-based superhydrophobic materials in the field of waterproofing,anti-icing,flame retardancy,and oil-water separation was discussed.Finally,the problems and development prospects of hydrophobic modification of cellulose-based materials were summarized and prospected.
