| 摘 要： | 采用溶液共混法将纳米ZnO颗粒添加到聚碳酸酯（PC）中，制备得到了具有高透明性、高紫外线屏蔽能力的PC/ZnO纳米复合高分子膜。分别使用傅立叶转换红外线光谱（FT-IR）、扫描电子显微镜（SEM）、紫外-可见分光光度计对纳米复合膜的光学性能进行了分析和表征。结果表明当纳米ZnO的添加量为10%（质量分数）时，复合膜的可见光透过率为98%，与未添加纳米ZnO的PC膜一致。与市售隔紫外线PC产品对比，纳米复合膜同时具有较好的透明度和紫外线屏蔽能力，紫外线的阻隔率可达92%。

| Abstract: | Highly transparent polycarbonate(PC)/ZnO nanocomposite films with good ultraviolet(UV)-shielding performance have been successfully obtained by a simple solution mixing method using cyclohexanone(CYC) as a co-solvent.The prepared nanocomposite films were characterized by Fourier transform infrared(FT-IR) spectroscopy,scanning electron microscopy(SEM),and UV-visible spectroscopy.The nanocomposite films exhibited good UV-shielding properties(above 92%) without loss of visible transparency(98%) even when the ZnO content was 10%(mass fraction).The as-prepared PC/ZnO composite films possess higher transmittance in the visible light region and better UV-shielding properties than a commercial product. |
