石墨烯纤维基可穿戴能量采集器OA

Graphene fibers(GFs)have demonstrated high strength,high electrical and thermal conductivity,mechanical flexibility,chemical stability,and good functionality,etc.at the macro-scale,and have been used in many different fields,particularly next-genera-tion wearable and flexible devices.This re-view provides an overview of recent advances in the fabrication of GFs,including wet spin-ning,confined hydrothermal synthesis,chem-ical vapor deposition,and other emerging techniques.Special emphasis is placed on the development of GF-based devices that con-vert solar,thermal,or moisture energy from the environment into electrical energy.The working principles,structural design,and performance of these devices are summarized and current challenges and prospects for their use in wearable energy systems are detailed.
