Research Progress in Nanocellulose Preparation

In recent years, under the current situation of the exhausting non-renewable resources such as coal, oil and natural gas, there is a general interest in the sustainable production of chemicals and/or materials from biomass, which may play a major role in producing systems traditionally produced from petroleum. Cellulose is one of the most widely distributed renewable biopolymers. nanocellulose prepared from renewable and biodegradable lignocellulosic materials is green and environmental-friendly. It holds promise in a wide range of applications due to its nanoscale dimension and some unique properties, such as optical, electrical, magnetic and mechanical properties, etc. This review introduces the research progress in nanocellulose preparation methods.
