Microcellulose Vs Nanocellulose – A Review

Cellulose is the most abundant and renewable natural semi-crystalline polysaccharide. This biopolymer an inexhaustible source of fibers (NFs), valuable raw material for production microparticles microcrystalline (MCC) powdered cellulose (PC), as well other micro-products, which are widely used in biomedicine, food additives, plastics, materials. In addition, has a nano-fibrillar architecture that promotes release free nanofibers (CNFs) nanocrystals (CNCs). review article describes preparation methods, structural characteristics, properties, applications different types micro- (NFs, MCC, PC) nano-cellulose (CNFs, CNCs). Two main shortcomings hindering wide application various Nano (NC) were discovered, such high expenses difficulty competing with commercial micro-cellulose. To reduce cost NC, waste-free technology can be used, allows completely utilize materials chemicals, produce cheap nanocrystalline aggregates (NCA) zero emission liquid solid waste. Due to low cost, nanostructured product, NCA, will quite competitive micro-celluloses (MCC, PC, etc.) e.g., filler thickener.
