Poly(p-phenylene sulphide), PPS, was gas- and solution-doped with AlCl3 and I2. Morphology and crystallinity changes introduced by the dopant were analysed. The solvent has an important role in the preservation of the original morphology and in the final electrical conductivity achieved. The doping increased the crystallinity index, and it is believed that both dopants were intercalated between the lamellae, decreasing the interplanar spacing, but not destroying the intracrystalline order. The highest conductivity was achieved with the system LDC-AlCl3-CH3NO2.
