Abstract

The outstanding electrical, optical, mechanical properties of graphene make it a promising material in flexible electronics and optoelectronics. 30-inch graphene films have been produced by Roll-to-roll transfer method as transparent electrodes. However, continuous mass production of high-quality graphene and efficient etching-free transfer of graphene to plastic substrates are still challenges for industrial scale application. Here, we designed and built a continuous roll-to-roll low-pressure chemical vapor deposition (CVD) system which is suitable to produce monolayer graphene film on industrial copper foil. We successfully transferred the large-area graphene onto PET plastic substrates using a facile roll-to-roll lamination and bubbling transfer process with the preservation of copper foil for reuse. The graphene/PET transparent electrodes exhibit a high transparency and a low sheet resistance, good flexibility, high robustness in various environments, and considerable uniformity. This continuous roll-to-roll production of graphene transparent electrode may accelerate its application in industry.
