Nanocellulose: Preparation, Characterization and Applications
The growth of nanocellulose has attracted outstanding interest in the last few decades due to its unique and potentially useful features. Novel nanocelluloses improve the strongly expanding field of sustainable materials and nanocomposites.CNCs and CNFs are two kind of nanocelluloses (NCs), and they own various superior properties, such as large specific surface area, high tensile strength and stiffness, low density, and low thermal expansion coefficient.Their application includesnanocellulose in transdermal drug delivery, Hydrogels, Aerogel Systems, Nanocellulose in Tablet Formulations and Nanocellulose in Microparticulate Drug Delivery (1). Different methods of nanocellulose like pretreatment method, mechanical process and chemical hydrolysis used for the synthesis of nanocellulose. Characterization of cellulose includes scanning electron microscopy, x-ray diffraction (XRD) analysis of samples and thermogravimetric analysis.
