Microwave-assisted liquefaction of rape straw in methanol was conducted to collect the liquefied residues for the extraction of cellulose nanocrystals (CNCs). The liquefied residue with content of 23.44% from 180C/7.5min was used to fibrillate CNCs with dilute alkali (2% NaOH) and hydrogen peroxide (5% H 2 O 2 ) treatments, followed by ultrasonication for 15min. The FT-IR spectra and SEM images...
