摘要：以氧化石墨(GO)为主体,苯胺一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.
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.
