ANTIBACTERIAL AND SELF-CLEANING COMPOSITE COATING FILM

The present invention relates to a composite coating film, which has transparency, a self-cleaning function, antibacterial properties, and excellent moisture and oxygen barrier properties. The film comprises: a film substrate; and at least two barrier layers consisting of cellulose-based nanofibers and chitin-based nanofibers substituted with guanidine, which are stacked layer by layer on the film substrate. In addition, the film comprises, on the other side thereof, a self-cleaning porous nano-coating layer in which chitin-based nanofibers substituted with guanidine and inorganic particle layers are alternately stacked layer by layer in two or more layers, wherein the coating layer also comprises an essential oil. The composite coating film provides excellent transparency, oxygen and moisture permeability, and antibacterial effects.
