We successfully fabricated a conductive E-textile and color-coated E-textile by depositing multilayer AlO/TiO on a conductive E-textile through atomic layer deposition (ALD). Pt was deposited on an E-textile as a conductive layer via low-temperature ALD. The color of the coated conductive E-textile could be tuned to violet, green, or pink by simply varying the thickness of the AlO and TiO layers. Both experimental and simulation results revealed that seven different colors can be obtained with single-layer TiO and multilayer AlO/TiO, depending on the film thickness and their refractive indices. This method is highly effective for enhancing the fastness of structural color on conductive E-textiles. Furthermore, the mechanical properties and chemical stability of the color-coated E-textiles were investigated. The color-coated E-textiles could withstand acidic and basic solutions, with almost negligible changes in their morphology; this in turn indicates their excellent chemical stability. These switchable stable color-based conductive E-textiles can be used as a platform to directly integrate future wearable electronics in textiles.
我们通过原子层沉积（ALD）在导电电子织物上沉积多层AlO/TiO，成功制备了导电电子织物和彩色涂层电子织物。通过低温ALD在电子织物上沉积Pt作为导电层。通过简单改变AlO和TiO层的厚度，可将涂层导电电子织物的颜色调整为紫色、绿色或粉色。实验和模拟结果均表明，根据薄膜厚度及其折射率，单层TiO和多层AlO/TiO可获得七种不同颜色。该方法对于提高导电电子织物上结构色的色牢度非常有效。此外，还研究了彩色涂层电子织物的机械性能和化学稳定性。彩色涂层电子织物能够耐受酸性和碱性溶液，其形态变化几乎可以忽略不计；这反过来表明它们具有出色的化学稳定性。这些可切换的基于稳定颜色的导电电子织物可作为一个平台，用于将未来的可穿戴电子设备直接集成到纺织品中。
