Nanocellulose manufacturing

Nanocellulose is a kind of nanoscale particle composed of cellulose molecules, with the size usually between 1 and 100 nanometers. It has been extensively researched and applied in recent years because of its excellent reproducibility, biocompatibility and mechanical properties.Nanocellulose has extremely high specific surface area and good solubility, so it has a wide range of application prospects, such as the preparation of biological materials, nanocomposites, electronic equipment, food additives and medicine, etc. In addition, nanocellulose is considered a sustainable material because it can be obtained from renewable plant sources and its production process is relatively environmentally friendly.
Cellulose is homogenized by high pressure, which produces strong shearing, impact and cavitation effects, thereby making liquid substances or solid particles with liquid as a carrier ultra-fine. After cellulose is subjected to mechanical stress, the specific surface area of the product increases with the number of homogenization times, and the water retention value also gradually increases. The high-pressure homogenizer can effectively destroy the fibril structure of cellulose, making the homogenized cellulose product more accessible and reactive.
