Abstract
In situ conductivity measurements on a polyaniline film with a fourprobe electrode are performed in NH 4F, 2.3HF and in propylene carbonate in the dark and under illumination. The conductivity is also determined on a pellet of chemically prepared polyaniline mixed with carbon black as for a battery electrode. The upper values of conductivities are 120 ohm −1 cm −1 in the hydrofluoric medium, 25 ohm −1 cm −1 in propylene carbonate and 8 ohm −1 cm −1 in the solid dry state. For a pellet with 20% carbon black it is 0.5 ohm −1 cm −1. The increase in conductivity of the polyaniline film in the solid state upon illumination is about 0.7 ohm −1 cm −1 (10%).
