“…[50] However, those peaks of PEDOT:PSS cannot be observed in the P-rGOA sample. [51,52] In addition, the 2D peak of P-rGOA is still obvious compared to those of rGO sample. Those results might be due to the less content of PEDOT:PSS in P-rGOA.…”

A versatile composite aerogel is developed by introducing of PEDOT:PSS in reduced graphene oxide, resulting in an ultrathin aerogel film around 100 µm thick. Like a tape, the aerogel can tightly attach to smooth or rough substrate, and there forms a self‐healable and anti‐vibration energy storage electrode. With a Ti foil substrate, the electrode offers an electrochemical capacity of 190 mF cm−2 at 0.1 mA cm−2 working current density. It also exhibits 98.7% capacitance retention after 10 000 charge/discharge cycles, with almost negligible capacitance decline even after eight damaging/healing cycles or 4000 vibrating cycles. With symmetrical aerogel‐based electrodes, a smart electrochemical device is explored as a sensor for sensitively detecting space electric field strength, ranging from 1100 to 19 000 V m−1. Simulation results verify that the response current in the sensor comes from the internal recombination current in the electrochemical device, which originates from ion recombination near the electrode substrate in space electric field. Further, a validation sensor experiment is designed and realized with affiliated modules, successfully monitoring space electric field.

“…Besides thermal treatment, electrochemical reduction and chemical reduction, other strategies including microwave and photoreduction, photocatalyst reduction, solvothermal reduction, and scanning atmospheric plasma have also been chosen for fabricating rGO‐based films . Whereas, all of these techniques still come with some limitations.…”

Graphene‐Based Transparent Conductive Films: Material Systems, Preparation and Applications

The rising demands of optoelectronic devices, such as flexibility, stretchability, and energy efficiency, urgently require alternative transparent conductive films (TCFs) for indium tin oxide. Among all the candidates such as carbon nanomaterials, metal nanomaterials, conductive polymers, and other nanocomposites, graphene is highly promising because of its distinct properties, such as outstanding conductivity, impressive optical transparency, remarkable mechanical flexibility, and chemical/thermal stability. However, the practical application of graphene‐based TCFs (G‐TCFs) is still challenging due to the difficulty for preparing large‐area crystalline graphene with few defects for TCFs. Many efforts have been made to solve these problems, and several kinds of optoelectronic devices have been successfully fabricated with G‐TCFs. This review presents the recent development in this area made by the authors and others, including the material systems and synthetic strategies of G‐TCFs, as well as their applications as transparent electrodes in optoelectronic devices such as field effect transistors, organic light‐emitting diodes, organic solar cells, and other devices. The current major challenges in this area and the potential practical solutions are identified.

“…20 Alotaibi et al used atmospheric air plasma operated at a high power (300 W, 20 kHz) and a high potential of B10 kV to reduce graphene oxide to conductive graphene films. 21 All these processes are not a low temperature process as the plasma is an arc discharge. Other attempts include APPJ treatment of graphene to increase hydrophilicity 22 and introduction of bandgap at an input power of 150 W. 23 In this study it will be shown that a APPJ can be used as tool for controlled doping graphene oxide.…”
