Method of determination of transient and steady‐state conductivity in polyethylene terephthalate ultrathin films

摘要

AbstractThe determination of transient and/or steady‐state conductivity of polyethylene terephthalate (PET) ultrathin films by means of electrode configurations involving any load or stress imposed on the measuring area during measurement usually leads to anomalous behaviours of the charging current and thus prevents a good evaluation of the electrical properties of the samples. This can be avoided by the use of a two‐electrode system with lateral contacts, to obtain reproducible results without any requirement for previous mechanical, thermal, or electrical treatments (as is often recommended in the literature), and that permits the characterization of industrial films down to 1.5‐μm thick in true storage conditions after production. © 1993 John WileySo
