结构着色薄膜具有颜色不变、机械强度优异、不透液等特点，因其在实际应用中的巨大优势而受到广泛关注。然而，来自相同蛋白石或反蛋白石结构的彩色薄膜总是具有不同的颜色外观。这个特点使得色彩控制变得非常复杂。这项研究提出了一种通过将 TiO2 和 PDMS 渗透到空心 SiO2 PC 中并随后进行固化过程来制造颜色不变的 PC 薄膜的有效方法。所得薄膜具有多种优点，例如增强的色彩饱和度、与原始PS@SiO2 PCs模板颜色相同、加宽半峰全宽（FWHM）、持久不变的色彩和增强的机械鲁棒性。此外，疏水性和可调阻带的结合对于油漆和建筑外部装饰的潜在应用具有重要意义。目前的结果为功能薄膜的研究开辟了新的前景。 (C) 2016 Elsevier Ltd. 保留所有权利。
Structurally colored films with invariable color, excellent mechanical robustness and liquids impermeable property have received extensive attentions due to its great advantages in practical application. However, colored films from the same opal or inverse opal structure always have different colored appearances. This character makes the color controlling become very complicated. This study presents an effective approach for fabricating PCs films with invariable colors by infiltrating TiO2 and PDMS into PCs of hollow SiO2 and followed with a curing process. The obtained films exhibit several advantages, such as enhanced color saturation, the same color with its original PS@SiO2 PCs templates, widen full-width-at-half -maximum (FWHM), long lasting invariable colors and enhanced mechanical robustness. Additionally, the combination of hydrophobicity and tunable stop-bands is significant for potential application in paint and external decoration of architectures. The present results open new vistas for the research of functional films. (C) 2016 Elsevier Ltd. All rights reserved.
