Microwave-assisted Production of Chlorinated Graphene Dispersion

Abstract

Chemically modified graphene and its dispersions are promising materials for several applications. The chemically inert characteristics of graphene, however, mean that chemical exfoliation and functionalization require a strong reactant and a long reaction time. To resolve the issues, we describe a novel microwave-assisted graphene modification technique using chloroform, by which chlorinated graphene was exfoliated and dispersed directly in the chloroform after irradiation for 15 min.

Spectroscopic Investigation of Plasma-Fluorinated Monolayer Graphene and Application for Gas Sensing

“…5−8 becomes the most practicable, convenient, and efficient approach to modulate the band structure and properties of graphene 9 and thus extend the applications in electronics and sensors. 6,10,11 Graphene halides, 12,13 one class of graphene derivatives, including fluoride, 14,15 chloride, 16,17 bromide, 18,19 and iodide, 20,21 have recently been investigated for the modification of graphene. Normally, fluorination is a p-doping-type covalent modification which could tailor the intrinsic properties of graphene.…”

One-step synthesis of chlorinated graphene by plasma enhanced chemical vapor deposition

“…Inside, the covalent modification of graphene is much reliable to apply in the future electronic device, in contrast with the physisorption of chemical species. Graphene halide [4,5], one of graphene derivative including fluoride [6,7], chloride [8,9], bromide [10][11][12] and iodide [12,13], have been recently investigated for the band gap engineering. Among them, graphene chloride is a p-doping type covalent modification of graphene which could tailor the intrinsic properties of graphene [14,15].…”
