The superhydrophobic surface constructed by biomass materials has received more and more attention because of its green and environmental protection,and can be used in food packaging,biomedicine and other fields.In this paper,the chemical composition,characteristics,preparation process and morphology of cellulose nanocrystals(CNC),lignin nanoparticles(LNP),and nano-chitosan were introduced,and the methods for constructing superhydrophobic surfaces using these biomass materials were reviewed.The applications of these sustainable superhydrophobic surfaces in oil-water separation,biomedicine,water collection,and food packaging were summarized.
