Using the CTCVD system, we first chose to investigate the relationship between the process velocity and the characteristics of graphene produced on Cu foil (see Methods). Experiments were performed at translation speeds between 25 mm/min and 500 mm/min, under identical temperature and gas flow … See more We next assessed the graphene uniformity by comparing Raman spectra taken across the width and length of each sample (see Supporting Information, Fig. S4a). Additionally, a long (4 m) Cu substrate was … See more Last, we sought to identify principles for improved R2R production of graphene using the CTCVD system. It is understood that annealing prior … See more WebNov 27, 2024 · In this work, we introduce a novel and facile method of exfoliating large-area, single-layer graphene oxide using a shearing stress. The shearing stress reactor consists of two concentric ...
