2018年3月1日 · In this work, we report a RGO film with a record-high conductivity of 6300 S cm −1 and a record-high mobility of 320 cm 2 V −1 s −1, which was reduced by Joule heating at an extremely high temperature of 3000 K. Thermal reduction process challenges of Joule heating were overcome by employing a two-step reduction and a curved RGO film.

2022年6月15日 · Herein, multilayered CNF/rGO aerogels are combined with a highly conductive rGO film to build composites, utilizing the absorption-reflection-reabsorption process to simultaneously improve their EMI shielding properties and EMWs absorption ability.

Reduced graphene oxide (RGO) films are promising in applications ranging from electronics to flexible sensors. Though high electrical and thermal conductivities have been reported for RGO films, existing thermal conductivity data for RGO films show large variations from 30 …

2024年12月2日 · Herein, a universal strategy is reported to synthesize large-area and ultrathin metal oxide nanoparticles (MONPs)/reduced graphene oxide (rGO) hybrid-structured films by attaching self-assembled film of a wide range of MONPs onto self-assembled rGO film and subsequent carbonization.

2024年7月17日 · Here, an ultra-smooth rGO nano-thin film, featuring wrinkle-free and a rather low surface roughness of 1.38 nm is developed, which is attributable to a steady and homogeneous thin liquid film confined by a conical fiber array. The thin liquid film facilitates both in-plane stacking of nanosheets and reducing the buried solvent under nanosheets.

2021年3月2日 · In this study, a kind of non-carbonized reduced graphene oxide (RGO)-CNF hybrid film is fabricated by a combination of filtration and chemical reduction. In the hybrid, introduction of CNF not only prevents the stacking of RGO but also endows the composite film good mechanical properties including mechanical strength and flexibility.
