WebbRaman spectroscopy was carried out under the 488 nm laser excitation over the temperature range from −190 to +100 °C. The extracted value of the temperature coefficient of Gmode of graphene is ł) −0.016 cm-1/°C for the single layer and ł) −0.015 cm-1/°C for the bilayer. The obtained results shed light on the anharmonic properties of ... Webb13 apr. 2024 · To promote the anticorrosion performance of epoxy/zinc (EP/Zn) coating, graphene oxide (GO) was directly incorporated into dual-component paint. Interestingly, it was found that the method of incorporating GO during the fabrication of the composite paints strongly influenced their performance. The samples were characterized by Fourier … Webb24 jan. 2024 · 3-Hydroxy-2-naphthoic acid hydrazide (HNH), a new reductant and modifier, was applied to reduce and modify graphene oxide (GO) in a one-step process.
