Flash photothermal treatment via Xenon lamp with a broad wavelength spectrum can effectively remove oxygen functionalities and restore sp2 domains at graphitic carbon materials. The chemical composition and relevant structure formation of flash reduced graphene oxide liquid crystal (GOLC) fibers are investigated in accordance with flash irradiation conditions. Owing to the spatial controllability...
In article number 1703934, Hyeon Su Jeong, Il‐Doo Kim, and co‐workers describe nitrogen‐doped graphene fibers functionalized by platinum catalytic nanoparticles for wearable humidity sensors. The nitrogen‐doped graphene fibers assembled twodimensional graphene sheets show rough and wrinkled surfaces. The platinum‐decorated graphene fiber exhibits high sensitivity and fast response speed, which can...
Humidity sensors are essential components in wearable electronics for monitoring of environmental condition and physical state. In this work, a unique humidity sensing layer composed of nitrogen‐doped reduced graphene oxide (nRGO) fiber on colorless polyimide film is proposed. Ultralong graphene oxide (GO) fibers are synthesized by solution assembly of large GO sheets assisted by lyotropic liquid...
