Electrical conduction in aromatic polyamides cmrcially known as N o m or HT-1 film is studied over a temperature range of 50°-200°C and eledric field strengths up to 400 kV m-l over a time range of 1-60 min.This material has excellent thermal and mechanical properties making it suitable for high temperature applications.Conduction currents are measured both as a function of electric field strength and time of application of voltage in as received film of 75-125 pthick. Measurements are also carried out on specimens which were heat treated for 6 hours at 26OOc.Thermally treated samples yielded lower but m r e reproducible currents.At low electric fields the conductivity is independent of the applied electric field strength or its polarity suggesting that it is ohmic. At higher field strengths (10-300 kV m-l) the current is both a function of t h e of application and the magnitude of the field strength. The conduction currents measured at various constant electric field strengths are examined in the light of Schottky, Poole-Frenkel and ionic conduction mhanisms. The latter is shown to yield reasonable results if suitable assumptions are m d e for s m of the parameters.
