Abstract
A textured film is provided which comprises nanocellulose. At least a first surface of the film comprises a patterned, textured surface formed by repeating protruding regions and at least one non-protruding region arranged between said protruding regions. A particular height difference between the protruding and non-protruding regions can give liquid repellent properties. Methods for making the textured film are also provided.
