Electrical conduction mechanism in cellulose acetate-butyrate polymer films

The electrical conduction mechanism in solution-grown cellulose acetate-butyrate films of thickness 5 μm has been studied in the sandwich configuration. The electrical conduction was investigated in the field and temperature ranges 0.5 × 10 6−10.0 × 10 6 V m −1 and 300–450 K, respectively. The resul...

Description
Summary:The electrical conduction mechanism in solution-grown cellulose acetate-butyrate films of thickness 5 μm has been studied in the sandwich configuration. The electrical conduction was investigated in the field and temperature ranges 0.5 × 10 6−10.0 × 10 6 V m −1 and 300–450 K, respectively. The results show that the Richardson-Schottky mechanism is dominant above the glass transition temperature whereas the hopping mechanism may be dominant below the glass transition temperature.
