A bulk scale process is implemented for the production of nanostructured film composites comprising unary or multi-component metal oxide nanoparticles dispersed in a suitable polymer matrix. The as-received nanoparticles, namely Al[Formula: see text]O[Formula: see text], SiO[Formula: see text] and TiO[Formula: see text] and binary combinations, are treated following specific chemical and mechanical processes in order to be suspended at the optimal size and composition. Subsequently, a polymer extrusion technique is employed for the fabrication of each film, while the molten polymer is mixed with the treated metal oxide nanoparticles. Transmission and reflection measurements are performed in order to map the optical properties of the fabricated, nanostructured films in the UV, VIS and IR. The results substantiate the capability of the overall methodology to regulate the optical properties of the films depending on the type of nanoparticle formation which can be adjusted both in size and composition.
采用批量规模工艺生产纳米结构薄膜复合材料，该复合材料包含分散在合适聚合物基质中的一元或多组分金属氧化物纳米颗粒。所接收的纳米颗粒，即Al₂O₃、SiO₂和TiO₂以及二元组合，经过特定的化学和机械工艺处理，以便以最佳尺寸和组成悬浮。随后，采用聚合物挤出技术制造每种薄膜，同时将熔融聚合物与经处理的金属氧化物纳米颗粒混合。进行透射和反射测量，以绘制所制备的纳米结构薄膜在紫外、可见和红外波段的光学特性图。结果证实了整个方法能够根据纳米颗粒形成的类型来调节薄膜的光学特性，纳米颗粒的形成在尺寸和组成上均可调节。
