한국어 초록

We report the preparation of sulfonated reduced graphene oxide (SRGO) by the sulfonationof graphene oxide followed by radiation-induced chemical reduction. Graphene oxideprepared by the well-known modified Hummer's method was sulfonated with the aryldiazonium salt of sulfanilic acid. Sulfonated graphene oxide (SGO) dispersed in ethanolwas subsequently reduced by γ-ray irradiation at various absorbed doses to produce SRGO.The results of optical, chemical, and thermal analyses revealed that SRGO was successfullyprepared by γ-ray irradiation-induced chemical reduction of the SGO suspension. Moreover,the electrical conductivity of SRGO was increased up to 2.94 S/cm with an increase of theabsorbed dose.
