摘要：Aniline/o-anisidine copolymer (P(An-co-oAs))-intercalated GO composite was synthesized by the delamination/reassembling method in N-methyl-2-pyrrolidone (NMP) solvent, and was characterized by FTIR, XRD, DSC, SEM, TGA, conductivity and cyclic voltammetry. XRD and FTIR spectra indicate that the P(An-co-oAs) exists as a monolayer of outstretched chains in the gallery of GO due to the hydrogen bonds between -NH, =N and -OCH3 groups of P(An-co-oAs) and the oxygen functional groups of the GO layers. The results of thermal analysis show that no de-intercalation of P(An-co-oAs) from GO occurred during heating. Its electrical conductivity has reached 1.9 X 10(-2) S/cm, which is by 3 orders of magnitude higher than that of GO. The intercalation of P(An-co-oAs) also has a pronounced effect on the stabilization of electrochemical response in relation to the GO matrix and P(An-co-oAs). (C) 2005 Elsevier Ltd.
