RESUMO

Theoretical experimental aspects of the Heat Pulse Technique (HPT) are presented. The applications were the measurements of surface potentials, charge centroid, and total charge of the film samples. No tentative was made to determinate the spatial distribution of the observed charges. The HPT was used as complement of TSC open circuits measurements in the study of conduction and polarization effects in 25?m Teflon FEP films for different initial conditions of the corona-charged samples: virgin samples, annealed, u.v. irradiated, and samples submitted to ionic glow discharge. Several problems were raised and some of them were treated using very simple theoretical models to interpret the experimental results.
