The decay of the surface potential of corona-charged 23Γ25 lm thick polyimide, polyethyleneterephthalate and polyetherimide samples, degraded by partial discharges, was determined. The samples were Γrst subjected in their centre part to A.C. voltages by a sphereΓplane electrode system at relative hu
Charge stabilities of various polar polymer homoelectrets were determined. Although these electrets are reasonably stable in dry environments, they rapidly discharge when exposed to humidity. The rate of charge decay was found to depend directly on the ability of these polymers to absorb water under
