| Abstract:In recent years, cellulose nanofibril (CNF) has attracted a considerable attention because of its unique physical and chemical properties. Currently, CNF is mainly obtained by mechanical treatment of cellulose fibers pretreated by using chemicals and enzyme．With the increasing awareness of environmental protection, the preparation methods of CNF including recoverable organic acid hydrolysis, deep eutectic solvents pretreatment combined with mechanical shearing are drawing extensive concern and attention from the academic. The preparation and modification methods of CNF were summarized in this review. The problems in the preparation and modification of CNF were summarized. Moreover, the advantages and disadvantages of various preparation methods were discussed. The environmentally friendly and efficient preparation methods of CNF and its latest application areas were also introduced in this paper. |
