The present invention provides a low energy method for preparing nanocellulose using selected organic or inorganic swelling agents. A low energy method for preparing a nonderivatized nanocellulose material, comprising the steps of: (a) treating a cellulosic material with a swelling agent to obtain a swollen cellulosic material; (b) the swollen cellulose material Subjecting the material to an effective mechanical grinding process such as high shear, high pressure homogenization, microfluidization, high friction, and combinations thereof, and (c) isolating the nanocellulose material Low energy method including. 【Selection chart】 None |
