Abstract :
Corona triode has been used for studying charge storage and transport properties of polypropylene (PP) films in controlled atmosphere of hydrogen. Studies of charging transient currents (I-t) and isochronal current-voltage (I-V) characteristics for one-side metallized samples are reported. Space charge limited currents, Schottky, Poole-Frenkel and hopping conductivity are discussed. The open-circuit thermally stimulated currents after positive and negative corona charging are also presented
