The structure of cellulose nanomaterials is definitized by random deposition and can’t change in response to shifting software necessities. Herein, we current a magnetic field-controlled cellulose movie derived from wooden that reveals nice magnetic properties and dependable tunability enabled by included Fe3O4 nanoparticles and cellulose nanofibers (CNF) with a big length-diameter ratio. Fe3O4 nanoparticles are dispersed in …
