Herein, we first reported a facile strategy to prepare functional Poly(vinyl alcohol) (PVA) hybrid film with well ultraviolet (UV) shielding property and visible light transmittance using graphene oxide nanosheets as UV-absorber. The absorbance of ultraviolet light at 300 nm can be up to 97.5%, while the transmittance of visible light at 500 nm keeps 40% plus. This hybrid film can protect protein from UVA light induced photosensitive damage, remarkably.
在此，我们首次报道了一种简便的策略，以氧化石墨烯纳米片作为紫外线吸收剂，制备具有良好紫外线屏蔽性能和可见光透过率的功能性聚乙烯醇（PVA）杂化膜。在300nm处紫外线的吸光度可达97.5%，而在500nm处可见光的透过率保持在40%以上。这种杂化膜能显著保护蛋白质免受UVA光诱导的光敏损伤。
