Recent advances in nanocellulose processing, functionalization and applications: a review

摘要: In recent years, environmental and ecological concerns have become a major issue owing to the expansion of petroleum-based synthetic materials products, therefore development novel effective that ecofriendly economical properties is significant interest. With improvements in nanotechnology, biopolymer nanocellulose has gained further attention its remarkable easy availability from various plant species agricultural waste such as rice husk, tea leaves, sugarcane bagasse so forth. Nanocellulosic wider applications, for example they are used bio-sensing, catalysis, wastewater treatment, drug delivery, tissue engineering, flame retardants on, their long-lasting nature, anisotropic shape, splendid biocompatibility, potent surface chemistry, efficacious mechanical optical properties. Chemical, mechanical, physicochemical enzymatic pretreatments can be utilized synthesize cellulosic waste. The features nanocellulosic mainly dependent on extraction technique, source efficient subsequent functionalization. Surface functionalization involves routes functionalization, example, provide ionic charges nano-cellulose via phosphorylation, carboxymethylation, oxidation sulfonation surfaces, or generate hydrophobic material acetylation, etherification, silylation, urethanization amidation. Functionalization through grafting polymer onto backbone also an interesting route applications dimensions. These modifications potential nanomaterials which reinforcing agents nanocomposites promotes specific production nanomaterials, with objective promoting field functionalized nanomaterials.
