Abstract
Protonation of PANI-EB in m-cresol with camphorsulphonic acid (CSA) was car ried out for different PANI/CSA ratios by addition of CSA to PANI in m-cres ol: 1(st)) at once; 2(nd))after 2 weeks. In the 2(nd) case PANI is doped ra ther by m-cresol than by CSA as evidenced by UV-VIS-NIR spectroscopy. As a result, the films cast from solutions prepared using the Ist procedure show ed the conductivity 4-5 orders higher that those obtained done by the 2nd o ne. A model of strong solvent-dopant competition is proposed to explain thi s behavior.
