“…After reduction, the structures and properties of rGO have been greatly changed. Many oxygen-containing groups are removed from GO, and the sp 2 structure of GO was restored to some extent, achieving a low carbon to oxygen ration ( Lazauskas et al, 2018 ). As a result, the electrical conductivity is significantly enhanced.…”

“…Except for chemical reduction, thermal reduction of GO is employed under vacuum inert or other conditions suitable for reduction between 300°C and 2,000°C ( Pei and Cheng, 2012 ; Wang et al, 2017 ). Photothermal reduction of GO can also be produced using laser with wavelengths under 390 nm ( Lazauskas et al, 2018 ). Moreover, Li et al reported that microwave heating could be used for the reduction of rGO in microwave ovens ( Li et al, 2010 ).…”

“…suggested the direct laser writing using a CW 405 nm semiconductor laser under ambient conditions. [ 49 ] Based on this approach, the lower direct laser writing speed and the higher power density conclude to more pores in thick rGO multilayers. The results from all the characterization techniques are in good agreement with the defunctionalization of carbon‐oxygen bounds and the removal of oxygen‐containing functional groups.…”

Herein, photothermal modification of nanocomposite films consisting of hydrated vanadium pentoxide (V 2 O 5 · n H 2 O) nanoribbons wrapped with graphene oxide (GO) flakes was performed via 405 nm direct laser irradiation. The combination of X-ray diffraction, X-ray photoelectron spectroscopy, Raman scattering, transmission electron microscopy, and scanning electron microscopy allowed comprehensive characterization of physical and chemical changes of GO/V 2 O 5 · n H 2 O nanocomposite films upon photothermal modification. The modified nanocomposite films exhibited porous surface morphology (17.27 m 2 g –1 ) consisting of randomly distributed pillarlike protrusions. The photothermal modification process of GO/V 2 O 5 · n H 2 O enhanced the electrical conductivity of nanocomposite from 1.6 to 6.8 S/m. It was also determined that the direct laser irradiation of GO/V 2 O 5 · n H 2 O resulted in considerable decrease of C–O bounds as well as O–H functional groups with an increase of the laser power density.
