Electrophysical Properties of Latent Tracks of Heavy Ions in Polymers

摘要

Poly(ethylene terephthalate) films irradiated by high-energy ions without additional etching have been studied. It has been shown that tracks of heavy high-energy ions in poly(ethylene terephthalate) may be considered to be single through capillaries suitable for studying electrophysical properties. It has been revealed that the surface electrical conductivities of electrolyte solutions (KCl, LiCl, MgCl_2, and BaCl_2) in the tracks of nonetched membranes are substantially higher, while the surface charges are noticeably lower, than those of etched membranes.
