Abstract

Purified cellulose was obtained from corn leaf, a crop residue by removing lignin and hemicellulose. Nanocellulose was prepared from the cellulose by sulfuric acid hydrolysis and ultrasonic treatment and characterization by XRD, FT-IR, TG and TEM to study its crystal morphology, physical, chemical structure and thermal stability. The results showed that the optimum hydrolysis temperature of corn leaf cellulose was 60℃, the hydrolysis time was 2 h, and the concentration of sulfuric acid was 60%. The diameter of the nanocellulose was about 8 nm, with length of 150~200 nm. The XRD pattern showed the NCC belonged to cellulose I, and the crystallinity of NCC was 66.5%, the pyrolysis temperature was 243.43℃. The NCC prepared from corn leaf could be excellent reinforcing materials for the manufacture of plastic and paper products.
