Research Progress on Hydrophobic Modification and Application of Cellulose Base Materials

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.
