| Abstract Scope |
Flexible hybrid films are finding increasing applications in functional devices. In this work, transparent ZnO nanoparticle (NP) and poly(methyl methacrylate) (PMMA) hybrid films are made for ultraviolet (UV) shielding. The tensile strength increases with the ZnO NP volume percent. The elongation at break also increases with the ZnO content increase until 10 vol%, after which the elongation at break stays constant. All the ZnO-PMMA films show UV absorption at ~365 nm wavelength, with an increasing degree for higher ZnO content samples and a corresponding light transmittance decrease at longer wavelengths. Long term UV irradiation leads to reduction in tensile strength and elongation at break, along with lower UV shielding performance. The optimal ZnO content is 5-10 vol% for the overall UV shielding performance. |
