摘    要:Transparent conductive graphene films are fabricated by the transfer printing of graphene aqueous dispersion followed by hydrohalic acids and thermal reduction. Results indicate that the graphene film reduced by hydroiodic acid (HI) reduction combined with thermal treatment shows a higher electrical conductivity than that reduced only by thermal treatment at the same transparency. A film with a sheet resistance of - 2400 D./sq at a transparency over 72% is obtained at a typical wavelength of 550 nm.

Abstract:Transparent conductive graphene films are fabricated by the transfer printing of graphene aqueous dispersion followed by hydrohalic acids and thermal reduction.Results indicate that the graphene film reduced by hydroiodic acid(HI)reduction combined with thermal treatment shows a higher electrical conductivity than that reduced only by thermal treatment at the same transparency.A film with a sheet resistance of~2400/sq at a transparency over 72%is obtained at a typical wavelength of 550 nm.
Keywords:graphene  hydroiodic acid  thermal reduction  sheet resistance
