LOW ENERGY METHOD FOR THE PREPARATION OF NON-DERIVATIZED NANOCELLULOSE

摘要

A low energy method for the preparation of nanocellulose using selected organic or inorganic swelling agents. The use of these swelling agents allows opening up the intercrystalline structure and partially the intracrystalline structure of cellulosic materials thereby achieving a reduction 5 in the energy required to subsequently process the resultant swollen cellulose material into nanocellulose.
