One-Pot Procedure for Isolation of Nanocrystalline Cellulose

Nanocrystalline Cellulose (NCC) is a green and renewable material that has recently gained huge interests. Due to its interesting properties it has a wide possible application range and can be used as reinforcement material in the construction industry as well as in drug delivery systems and as material for implants. However, at the moment its complicated and expensive manufacturing process represents a significant obstacle to a widespread application of NCC. The present invention is characterized by a neutralization step terminating the acidic hydrolysis of the cellulose fibers during the production procedure. This uncomplicated, but very effective further step enables an ?easy-made-separation? of the NCC by centrifugation. Therefore, this innovative technology will pave the way for a wide range of applications of this fascinating new material.
