Preparation and Characterization of Nanofibriled Cellulose via High Frequency Ultrasonication from Cornstalk

Abstract:

To obtain nanofibriled cellulose (NFC) with uniform diameter and high aspect ratio, chemical pretreatment was employer to remove the hemicellulose and lignin of cornstalks with further ultrasonic treatment. The prepared samples were characterized by SEM, TEM, FTIR, XRD, and TG. Results showed: The obtained NFC possessed the uniform diameter of about 25 nm and high aspect ratio (>300). The crystalline type of NFC was cellulose I type. The NFC with high crystallinity, high aspect ratio, and nanoscale is a newly great potential nanomaterial in different fields.
