摘要
采用原位聚合法制备了聚苯胺／纳米石墨微片（PANI／NanoG）导电复合材料。结果表明，NanoG的直径约为1～20μm，厚度为30-90nm，径厚比为300-500；PANI均匀覆盖在NanoG表面；当NanoG体积含量为2．30％时，复合材料电导率达到5．16S／cm，其渗滤阈值达到2．30％，NanoG的高比表面积及在PANI中的分散造就了复合材料良好的导电性能。
Polyaniline （PANI） was a typical conducting polymer while graphite nanosheets （NanoG） are materials of high specific surface. Composites of PANI with NanoG were prepared via an in situ polymerization of aniline （ANI） in the presence of NanoG. Results showed that NanoG had a thickness ranging of 30-90 nm and diameter ranging Of 1-20μm, and diameter to thickness ratio was 300-500. The composites exhibited a high electrical conductivity of 5. 16 S/cm when the NanoG content was 2.30 vol%, and the percolation threshold of the composites was as low as 2.30 vol%. This great improvement of conductivity could be attributed to the high aspect ratio of NanoG.
