Recent advances in graphene-based freestanding paper-like materials for sensing applications

Publication date: August 2018Source: TrAC Trends in Analytical Chemistry, Volume 105Author(s): Yao Yao, Jianfeng PingAbstractThere has an increasing demand on the fabrication of flexible, light-weight, robust, cost-effective, and eco-friendly freestanding paper-like materials in view of their promising applications in energy devices, sensors, actuators, and chemical filters. With the unique planar structure and outstanding properties, graphene has been recognized as the most promising building block for the development of freestanding paper-like materials for various specific applications. Here, we highlight recent progress of graphene-based freestanding paper-like materials for sensing applications. The fabrication methods for graphene-based freestanding paper-like materials are introduced completely. Three main characteristics of graphene-based freestanding paper-like materials, including mechanical performance, electrical conductivity, and biological property, are also present. The sensing applications of graphene-based freestanding paper-like materials such as electrochemical sensors, resistance sensors, and deformation sensors are discussed in details.
