“…Graphene oxide (GO) was chosen as the hydrophilic coating, which was produced by plasma oxidation of graphene deposited on a copper substrate by a low-pressure chemical vapor deposition (LPCVD) technique. GO is hydrophilic in nature , and thanks to its extremely high thermal conductivity on metallic Cu surface, it does not put a barrier against the heat dissipation of the surface, which helps to keep the surface cool for the enhanced water condensation. As a second step, a thin (<100 nm) film of a low-surface energy fluorinated polymer was deposited on top of hydrophilic GO surface by the initiated chemical vapor deposition (iCVD) method.…”

This study examines the fog-harvesting ability of graphene oxide surfaces patterned by hydrophobic domains. The samples were prepared from graphene deposited using low pressure chemical vapor deposition, which was later plasma oxidized to obtain hydrophilic graphene oxide (GO) surfaces. Hydrophobic domains on GO surfaces were formed by initiated CVD (iCVD) of a low-surface-energy poly(perfluorodecyl alkylate) (PPFDA) polymer. Hence, patterned surfaces with hydrophobic/hydrophilic contrast were produced with ease in an all-dry manner. The structures of the as-deposited graphene and PPFDA films were characterized using Raman and Fourier transform infrared spectrophotometer analyses, respectively. The fog harvesting performance of the samples was measured using the fog generated by a nebulizer, in which the average diameter of the fog droplets is comparable to meteorological fog. According to the fog harvesting experiment results, 100 cm 2 of the as-patterned surface can collect fog up to 2.5 L in 10 h in a foggy environment. Hence, hydrophilic/hydrophobic patterned surfaces in this study can be considered as promising fog harvesting materials. Both CVD techniques used in the production of hydrophilic/hydrophobic patterned surfaces can be easily applied to the production of large-scale materials.
