Abstract :
The present work is concerned with experimental results on the electrical conductivity of chitosan and chitosan acetate in the temperature range 20 to 325 K, and a broad range of electric field strength. The thickness of the layers was ~15 μm. The influence of the internal structure on electrical properties was observed. The mechanism of the electrical conductivity was controlled by the Poole-Frenkel effect with contribution of hopping or tunneling from deep traps
