Cellulose nanofibril （CNF） is a novel nanofiber with diameter less than 100 nm and composed of fibrils and fibril aggregations, which is disintegrated from native fiber by using high speed-and-pressure ＇mechanical shear, or a combination of both chemical （ or enzymatic） pretreatment and mechanical fibrillation. Excepting abundance, renewability and biodegradation, CNF possesses other outstanding advantages such as excellent mechanical properties, well light transparency, large surface area and high reactivity, and becomes to one of the stu...
