Abstract: Aniline/o-anisidine copolymer (P(An-co-oAs)) intercalated graphite oxide (GO) composites were synthesized through the delamination/reassembling method using GO as host and conducting P(An-co-oAs) as guest. FTIR spectra indicate that the hydrogen bonds are formed between the amino groups of P(An-co-oAs) and the carbonyl groups on the internal layers of GO. XRD and TEM results show that the P(An-co-oAs)/GO composites maintain good lamellar structure, and the interlayer spacing of GO is enlarged with the increase of the added amount of P(An-co-oAs). The electrical conductivity of the composites is 2 to 3 orders of magnitude higher than that of the GO. The intercalation of P(An-co-oAs) also has a pronounced effect on the electrochemical properties of the GO.
