Abstract
The present disclosure relates to a functional bacterial nanocellulose film and a method for preparing the same, and provides a functional bacterial nanocellulose film in which the coating of berberine chloride on the bacterial nanocellulose film reduces oxygen permeability and water vapor permeability, while enhancing ultraviolet blocking ability and antibacterial properties.
Claims15
A method for preparing a functional nanocellulose film, the method comprising:
- (a) producing bacterial nanocellulose by subjecting bacterial cellulose to electron beam irradiation and high-pressure homogenization;
- (b) producing a nanocellulose film from the bacterial nanocellulose produced in step (a);
- and
- (c) coating berberine chloride on the nanocellulose film produced in step (b).
