Preparation and evaluation of nanocrystalline cellulose aerogels from raw cotton and cotton stalk

Suspensions of nanocrystalline cellulose (NCC) were prepared by sulfuric acid hydrolysis of cotton and cotton stalk bleached pulps. The original pulps extracted from cotton and cotton stalk were analyzed by FT-IR spectroscopy, X-ray diffraction and scanning electron microscopy. The NCC products were investigated and their differences in morphology and other characteristics such as crystallinity index (CrI), zeta potential, particle size and...
