Abstract: Based on the gradual implementation of China's "plastic restriction order" to "plastic ban order", the use of renewable and degradable biomass-based materials instead of plastics has become a research hotspot. Cellulose is the most abundant renewable biomass resources in nature. Replacing plastic with green degradable cellulose-based materials is an effective approach to solve plastic pollution. The preparation methods of cellulose-based hydrophobic-oleophobic film materials, cellulose-based hydrophobic-oleophobic paper materials and cellulose-based hydrophobic-oleophobic gel materials are introduced in this paper. The characteristics of different preparation methods of these three cellulose-based hydrophobic-oleophobic materials are analyzed and compared, and the application of cellulosic hydrophobic-oleophobic materials in the fields of water-oil separation, wear-resistant textile materials and flame-retardant materials are expounded. The hydrophobic-oleophobic mechanism are explained. The development direction of cellulose-based hydrophobic-oleophobic materials is also prospected.
