제목 Facile, Efficient Liquid Exfoliated Cyanoethylated Cellulose Nanofibrils and Their Application
초록 Traditionally, cellulose nanofibers are difficult to disperse in organic solvent and redisperse after drying, and thereby limit their practical applications. Herein, we develop a new, convenient, scalable and energy efficient method for producing cyanoethylated cellulose nanofibers. Through the synergy of mechanical and chemical reaction processes, the produced cyanoethylated cellulose nanofibers are ca. 3 nm wide and several hundred to 1000 nanometers long. Particularly, compared with common TEMPO oxidized cellulose nanofibrils, they show improved hydrophobicity and redispersibility in different organic solvent. In addition, these dispersed CCNFs also exhibit greater potential to construct high-performance structural materials, e.g., transparent ductile nanopapers with large elongation up to 18% and toughness as high as 16.5 MJ/m3.
