采用脉冲激光轰击制备聚苯胺原位修饰的纳米石墨溶胶，与聚苯胺形成杂化薄膜材料，用标准四探针电导率测试，FT—IR，TG-DSC，TEM，XRD等手段对其进行表征。结果表明，脉冲激光轰击制备的聚苯胺原位修饰的纳米石墨粒径较小，能保持较小粒径均匀分散在聚苯胺体系中，纳米石墨与聚苯胺分子链之间存在强烈的相互作用，使聚苯胺分子链上电子云离域性增大，热稳定性和结晶度提高；电导率分别比石墨和聚苯胺孤立体系高16．7％和63％。

The conductive polyaniline film, doped with in situ decorated nano-graphite sol prepared by pulsed laser ablation, was tested by standard four-probe method and characterized by FT-IR, TG-DSC, TEM and XRD. The results showed that the in situ decorated nano graphite has a relative smaller particle size and is homo dispersed in polyaniline system. The nano graphite has a strong interaction with polyanilinc molecular chain and thus increases the electron cloud delocalization. The thermal stability and crystallization are also improved. The conductivity of the hybrid system is 15.7% and 63% higher than graphite and polyaniline respectively.
