Abstract
Graphene is an ideal material for flexible sensors with outstanding stretchability and extensibility, but its further development is being severely hindered by the existing multi-step routes. Laser-induced graphene (LIG) is a recently emerging technology that enables industrial scale preparation with mask-free, fast-scanning speed, and high spatial resolution. In this review, the latest advances on three-dimensional porous LIG from the perspective of precursor selections to manufacturing methods are presented. First, the commonly precursors such as graphene oxide, polymers, and natural materials for photothermal/chemical transformation was classified in combined with auxiliary processing equipment. Then, three all-purpose fabrication strategies, including casting-and-peeling transfer, topology architecture and Kirigami design, are summarized for the LIG-based sensors. Next, the representative progress of flexible/stretchable LIG-based pressure, strain, liquid, and gas sensors were categorized based on sensing principles, with the aim of improving the sensing performance in practical applications. Finally, the newest developments, major challenges, and outlook in LIG-manufacturing and integrated flexible sensors are discussed, showing huge potential in future wearable electronics.
石墨烯是柔性传感器的理想材料,具有出色的拉伸性和延伸性,但现有的多步骤制备方法严重阻碍了石墨烯的进一步发展。激光诱导石墨烯(LIG)是最近兴起的一种技术,可实现无掩膜、快速扫描和高空间分辨率的工业规模制备。本综述从前驱体选择到制造方法的角度,介绍了三维多孔石墨烯的最新进展。首先,结合辅助加工设备对氧化石墨烯、聚合物、光热/化学转化天然材料等常用前驱体进行了分类。然后,总结了基于 LIG 的传感器的三种通用制造策略,包括浇铸-剥离转移、拓扑结构和 Kirigami 设计。接着,根据传感原理对基于 LIG 的柔性/可拉伸压力、应变、液体和气体传感器的代表性进展进行了分类,旨在提高实际应用中的传感性能。最后,讨论了 LIG 制造和集成柔性传感器的最新发展、主要挑战和前景,展示了未来可穿戴电子产品的巨大潜力。
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
