近年来，基于透明和导电膜的电子器件在各种可穿戴和集成显示设备中吸引了大量的研究兴趣。透明电子器件的故障促使了集成了可修复性的透明电子器件的发展。一种可修复的透明化学气体传感器装置，通过开发在可修复的基底上浇铸透明碳纳米管（CNT）网络的有效方法，由逐层组装的透明可修复多层膜组装而成。在自修复基底上具有透明性和上级网络结构的可修复的含CNT网络的膜通过下面的自修复层的横向移动以使CNT层的分离区域重新接触而获得。由于一维受限网络结构、相对高的载流子迁移率和大的表面积与体积比，所制备的可修复透明膜组装成可修复透明化学气体传感器器件，用于在室温下的柔性、可修复的气体传感。该可修复透明化学气体传感器表现出优异的感测性能、稳健的可修复性、可靠的柔性和良好的透明度，为开发具有降低的原材料消耗、降低的维护成本、提高的寿命和稳健的功能可靠性的柔性、可修复透明光电器件提供了有希望的机会。
Transparent and conductive film based electronics have attracted substantial research interest in various wearable and integrated display devices in recent years. The breakdown of transparent electronics prompts the development of transparent electronics integrated with healability. A healable transparent chemical gas sensor device is assembled from layer-by-layer-assembled transparent healable polyelectrolyte multilayer films by developing effective methods to cast transparent carbon nanotube (CNT) networks on healable substrates. The healable CNT network-containing film with transparency and superior network structures on self-healing substrate is obtained by the lateral movement of the underlying self-healing layer to bring the separated areas of the CNT layer back into contact. The as-prepared healable transparent film is assembled into healable transparent chemical gas sensor device for flexible, healable gas sensing at room temperature, due to the 1D confined network structure, relatively high carrier mobility, and large surface-to-volume ratio. The healable transparent chemical gas sensor demonstrates excellent sensing performance, robust healability, reliable flexibility, and good transparency, providing promising opportunities for developing flexible, healable transparent optoelectronic devices with the reduced raw material consumption, decreased maintenance costs, improved lifetime, and robust functional reliability.
