Fabrication, structural evolutions and properties of large-area orientation reduced graphene oxide films by self-assembly at the air-water interface and thermal treatment

摘要

A very facile and efficient method was supplied to fabricate the large-area orientation RGO films by the interface self-assembly and low-temperature thermal reduction. The structural evolutions of RGO films were systematically investigated by AFM, FT-IR, Raman scattering and XPS spectra. The conductivity and wettability of RGO films with temperature changes were quantitatively evaluated by the four-probe measurement and contacted angle testing. As a result, the RGO films could be well reduced in the 200 similar to 300 degrees C for 2 h under air atmosphere. (C) 2020 Elsevier B.V. All rights reserved.
