Summary:An experimental study of iodine-doped half oxidized polyaniline (EB) films has been carried out. In the case of a low iodine concentration up to 500 mg/100 mL, the iodine oxdized benzene-diamine blocks to form quasi-delocalized polarons within the blocks. The resulting iodine-doped EB, however, was essentially amorphous and the electrical conductivity was too low to detect. At a higher iodine concentration than 1g/100 mL, the quinone-diimine blocks were also oxdized, polarons were delocalized over the whole EB-molecular chain, and a certain crystallization occurred in the chains. As the iodine content increased, the conductivity increased rapidly and satulated.
