For a single nano-optical material, it is difficult to possess high transmittance and adequately filter ultraviolet (UV) and infrared radiation (IR) simultaneously. Consequently, hybrid nano-optical materials comprising components of appropriate proportions for superimposing serviceable optical property are required. The design, optimization and processing of new composite blends with an aim to creating defect free thin films is far from a trivial endeavor. In this report, optimum composition and optical properties of hybrid nano-optical material has been determined and improved by crossover matching experiments and ball milling, respectively. Film preparation has been optimized to reduce defects expressed as cracks, tiny bubbles, strips, groove points, corrugation, and formation of acicular fibers by regulating proportion of polyvinyl butyral colloid and dry film processes. Two ameliorative processing conditions are exemplified where the resultant composite films possessed 86% maximum transmittance in the visible range and 90% and 50% blocking rate with respect to the IR and UV bands.

通过优化纳米材料的组合，设计并制备具有优异光学性能和改善隔热性能的透明杂化复合薄膜。

对于单一的纳米光学材料，难以具有高透射率并且难以同时滤除紫外线（UV）和红外辐射（IR）。因此，需要包含适当比例的组分以叠加有用的光学性质的杂化纳米光学材料。旨在创建无缺陷薄膜的新型复合材料共混物的设计，优化和加工远非轻而易举。在本报告中，已经分别通过交叉匹配实验和球磨确定并改进了混合纳米光学材料的最佳组成和光学性能。已优化膜的制备，以减少表现为裂纹，微小气泡，条带，凹槽点，波纹，通过调节聚乙烯醇缩丁醛胶体的比例和干膜工艺来形成针状纤维。举例说明了两种改善的加工条件，其中所得的复合膜在可见光范围内具有86％的最大透射率，并且相对于IR和UV带具有90％和50％的阻断率。
