摘要：
Highly conductive polypyrrole/graphite nanosheets/Gd3+ (PPy/nanoG/Gd3+) composites are fabricated via in situ polymerization using p-toluenesulfonic acid as a dopant and FeCl3 as an oxidant. The effects of the graphite nanosheets and Gd3+ loading on the electrical conductivity are investigated. The maximum conductivity of PPy/nanoG/Gd3+ composites about 17.86 S/cm found with 3 wt% graphite nanosheets and 6 wt% Gd3+ at room temperature. The results showed that the high-aspect-ratio structure of graphite nanosheets played an important role in forming a conducting network in PPy matrix. Thermal gravimetric analysis demonstrates an improved thermal stability of PPy in the PPy/nanoG/Gd3+ composites. The microstructures of PPy/nanoG/Gd3+ are evidenced by the SEM and TEM examinations.
