摘要： 以氧化石墨(GO)为主体, 苯胺-邻甲氧基苯胺导电共聚物(P(An-co-oAs))为客体, 采用剥离/重新组装技术合成出P(An-co-oAs)嵌入GO复合材料. FTIR分析显示, P(An-co-oAs)的N-H基团与GO片层中的C=O基团存在着氢键作用. XRD和TEM分析表明, P(An-co-oAs)/GO保持良好的层状结构, 且随着P(An-co-oAs)含量的增加, 复合材料的层间距不断扩大. P(An-co-oAs)的插入, 使得复合材料的室温电导率比GO提高2～3个数量级. 同时发现, 增加P(An-co-oAs)的含量, 不仅提高了GO的电化学活性, 也改善了GO的锂离子嵌入/脱嵌的循环稳定性.

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.

Key words: conducting polymer, graphite oxide, delamination/reassembling method
