SOLID-STATE PROTONATION AND ELECTRICAL-CONDUCTIVITY OF POLYANILINE

Polyaniline base was protonated by blending with camphorsulfonic and p icric acids in the solid state. The electrical conductivity of the equ imolar mixture was more than 10(7) times higher compared with the cond uctivity of components used for blending. The electrical conductivity still increased several times after heating of mixtures to 85 degrees C. The protonation is reflected by the changes in the infrared spectra . The dependences of the electrical conductivity on the composition of blends differ for the partly protonated polyaniline and mixtures of p rotonated polyaniline with an excess acid.
