Abstract: The present disclosure relates to oxidized carbon nanoparticles, and a method for producing same. The oxidized carbon nanoparticles are nano-sized spherical particles of oxidized carbon have a C/O atomic ratio from X-ray photoelectron spectroscopy (XPS) of 1 to 9, and the largest fraction of oxygen thereof from XPS is observed in a C—O(OH) bind. The oxidized carbon nanoparticles have better physical properties than typical carbon materials such as graphite or carbon black, and the producing process thereof is economical and environmentally-friendly. Further, the oxidized carbon nanoparticles may be applied as a filling material of an organic/inorganic composite, and when applied as such, is environmentally-friendly, economical, exhibits excellent dispersion properties, and may be immediately used without post-processing, such as functionalization.

Abstract: Described embodiments include a graphene membrane film for solvent purification and related method, and a solvent purification system using same. The graphene membrane film for solvent purification is formed having a plurality of stacked graphene plate-shaped flakes, and at least one pair of the plurality of stacked graphene plate-shaped flakes comprises a physical bond or a chemical bond connecting layers. The graphene membrane film for solvent purification is produced by preparing a graphene oxide dispersion liquid by dispersing graphene oxide in distilled water; confining the graphene oxide dispersion liquid between a pair of substrates; and applying heat and pressure to the graphene oxide dispersion liquid between the substrates to perform a hydrothermal reaction to concurrently thermally reduce the graphene oxide and bind graphenes. Due to lipophilic surface property and fine pores, size exclusion separation and hydrophilic-lipophilic component separation through polarity may be realized, and thus is usable in fine chemistry fields.
