Abstract

Highly conductive polypyrrole/graphite nanosheets/Gd^3+^ (PPy/nanoG/Gd^3+^) composites are fabricated via in situ polymerization using p‐toluenesulfonic acid as a dopant and FeCl~3~ as an oxidant. The effects of the graphite nanosheets and Gd^3+^ loading on the electrical conductivity are investigated. The maximum conductivity of PPy/nanoG/Gd^3+^ composites about 17.86 S/cm found with 3 wt% graphite nanosheets and 6 wt% Gd^3+^ 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/Gd^3+^ composites. The microstructures of PPy/nanoG/Gd^3+^ are evidenced by the SEM and TEM examinations. POLYM. COMPOS., © 2011 Society of Plastics Engineers.
