This work investigates the ultraviolet (UV) shielding property of composite films synthesized with graphene oxide (GO) nanosheets and regenerated cellulose. Regenerated cellulose was prepared from ZnCl2/CaCl2/GO solution. The GO sheets presented a homogenous dispersion in the film matrix. The incorporation of GO endows the cellulose films with improved UV shielding capacity. When GO loading reaches 2%, the UVA and UVB blocking percentages are 66.7% and 54.2%, respectively. Moreover, the composite films had excellent visible light transmittance. The resulting films possess promising applications as protective and packing materials.
