Abstract
Graphite oxide-Nafion hybrids with a high degree of alignment are cast from aqueous solution in the absence of any external field and reduced in situ by exposure to hydrazine to produce graphene-Nafion hybrids. Dramatic enhancement of electrical conductivity indicates sufficient accessibility of the inorganic nanosheets to the reducing agent, through the nanochannels formed by the polymeric ionic domains. © 2010 Wiley-VCH Verlag GmbH & Co.
