| 摘要: 膨胀石墨经过超声处理制备了纳米石墨薄片。以其为导电填料，对甲苯磺酸为掺杂剂，FeCl3·6H2O为氧化剂，引发吡咯单体发生原位聚合，制备出纳米石墨薄片/聚吡咯(NanoGs/PPy)复合材料。利用红外光谱(FTIR)、扫描电镜(SEM)和透射电镜(TEM)表征了材料的组成和结构。结果表明，石墨薄片被聚吡咯完全包覆；并且以纳米级尺寸分散在聚吡咯基体中。热失重(TG)分析和电导率测试结果表明，复合材料的耐热性能和导电性能较纯聚吡咯有所提高。 | |

| Abstract: Graphite nanosheets (NanoGs) were prepared by treating the expanded graphite with sonication in aqueous alcohol solution. The graphite nanosheets/polypyrrole (NanoGs/PPy) composites were fabricated via in situ polymerization of pyrrole monomer in the presence of NanoGs, using p-toluene-sulfonic acid and FeCl3·6H2O as dopant and oxidant, respectively. The structure of nanocomposites was characterized by FTIR, SEM and TEM. The results show that NanoGs are embedded in PPy matrix, and the dispersion of graphite sheets is in nanoscale. The thermal stability and electrical conductivity of NanoGs/PPy nanocomposites are superior to pure PPy as shown by TG analysis and electrical conductivity test. | |
