Claim:
1. A method for preparing a cellulose-zinc oxide nanocomposite, the method comprising the steps of: mixing an organic solvent with a surfactant at a weight ratio of 1:3-1:10 and adding zinc oxide nanoparticles thereto to prepare a mixed solution; adding a cellulose solution to the mixed solution, followed by stirring; subjecting the stirred solution to a casting process and a washing process to prepare a cellulose film having zinc oxide seeds produced thereon and/or therein; and forming a zinc oxide layer on the cellulose film by growing zinc oxide crystals from the zinc oxide seeds wherein the cellulose film having the zinc oxide seeds is added to an aqueous solution containing zinc source and an amine-group containing compound, followed by stirring the aqueous solution at a temperature of 60-90° C. for 2-10 hours.
