Abstract: The method for producing a nanocellulose support comprises coating a container with surface-treated nanocellulose solution, forming a nanocellulose thin film by drying the coated nanocellulose solution, and modifying the surface properties of the nanocellulose thin film by means of electron beam irradiation. According to an embodiment, the production of nanocellulose supports using the drying method allows substrates of various shapes to be coated and has simple processes, thus allowing mass production and production of over-sized supports.
