Optically transparent glass integrated with other functions, especially water/fog/ice/contaminate-repellent ability, is highly demanded for electronic displays, vehicle windshields and large-area building windows. Yet, the functional glass currently used in most of these applications faces challenges in integration fabrication and the trade-off between intrinsic optical property and imparted new functions, despite some advances in transparent superhydrophobic glass over the past decade. To this end, inspired by the functional hexagonal microstructure array of mosquito compound eye, a novel strategy to achieve multifunctional integration glass (MIG) is developed for omni-repellency towards water/fog/ice/contaminants in practical applications. The laser textured MIG performed well in durability and transmittance (about 98% of the pristine glass transmittance), which might be ascribed to the microstructure optimization. Moreover, some capabilities are also endowed to this glass, including a diversified self-cleaning ability for a variety of contaminants, a stable antifogging performance in dense fog environment, and an outstanding icing delay effect at low temperature. This work provides a promising fusion concept toward the design of multiplexed platforms that can integrate different functions in one glass for commercially versatile glass.

具有生物排斥功能的玻璃,结合了激光图案化的六角形纹理,具有多重排斥能力

集成有其他功能(特别是防水/防雾/防冰/防污染功能)的光学透明玻璃,对于电子显示器,车辆挡风玻璃和大面积建筑窗户非常需要。然而,尽管在过去的十年中透明超疏水玻璃取得了一些进步,但目前在大多数这些应用中使用的功能玻璃在集成制造以及固有光学性能与赋予新功能之间的权衡方面都面临挑战。为此,受蚊子复眼功能性六边形微结构阵列的启发,开发了一种实现多功能集成玻璃(MIG)的新颖策略,以在实际应用中实现对水/雾/冰/污染物的全防护。激光织构的MIG在耐久性和透射率(约占原始玻璃透射率的98%)方面表现良好,这可能归因于微结构的优化。此外,这种玻璃还具有一些功能,包括对多种污染物的多样化自清洁能力,在浓雾环境中稳定的防雾性能以及在低温下的出色的结冰延迟效果。这项工作为多路复用平台的设计提供了一种有前途的融合概念,该平台可以将不同功能集成到用于商用通用玻璃的一种玻璃中。在浓雾环境中具有稳定的防雾性能,并在低温下具有出色的结冰延迟效果。这项工作为多平台设计提供了一种很有前途的融合概念,该平台可以将不同功能集成在一块玻璃中,以实现商用玻璃。在浓雾环境中具有稳定的防雾性能,并在低温下具有出色的结冰延迟效果。这项工作为多平台设计提供了一种很有前途的融合概念,该平台可以将不同功能集成在一块玻璃中,以实现商用玻璃。
