摘要: A process for producing cellulose nanocrystals (CNCs) involves providing a cellulosic material, contacting the cellulosic material with an inorganic persulfate at an elevated temperature to produce CNCs, and recovering the CNCs. The process permits one-step production of CNCs from vegetative biomasses such as flax and hemp. Cellulose nanocrystals produced by the process with carboxylic groups are more uniform and have higher aspect ratios than CNCs produced by prior art processes.
