摘要
以纳米石墨薄片为导电填料,通过苯胺和α,ω-双(对氨基苯基)聚乙二醇(BAPPEG)共聚,成功的制备了纳米石墨薄片/聚苯胺-g-聚乙二醇(NanoGs/PANI-PEG-PANI)复合材料。研究了掺杂剂的种类、掺杂剂的浓度以及纳米石墨薄片的用量对材料导电性能影响。并利用红外光谱(FTIR)、扫描电镜(SEM)表征了材料的组成和结构。结果表明制备出均匀的膜状材料且具有良好的导电性能。材料的导电率分别达到了3.4和16.9S/cm。
The NanoGs/PANI-PEG-PANI composites were fabricated via polymerization of aniline monomer and BAPPEG in the presence of NanoGs which was used as electric filling. The kind of doped acids, the concentration, and the content of the graphite nanosheets as impact factors to the conductivity of the material was investigated. The structure of composites was characterized by FT-IR, SEM. The results showed the materials with even film structure have excellent conductivity. The conductivity reached to 3.4 and 16.9 S/cm respectively.
