Abstract: 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.

Abstract: The present invention provides a method for the production of chemically derivatized nanocellulose, comprising the step of a. contacting a precursor cellulosic material with a chemically derivatizing composition to form a liquid reaction mixture, and b. chemically reacting the formed liquid reaction mixture, and c. subjecting the formed liquid reaction mixture to microfluidisation, wherein the steps b. and c. are carried out simultaneously.
