Abstract
A study of pore formation in polyimide films irradiated with high-ener gy argon, krypton, or tungsten ions and subsequently treated with conc entrated hydrogen peroxide is presented. The dimensions of the destruc tion zone and those of the area of polymer structure modification and increased chemical stability are estimated. The rate of polyimide etch ing along the tracks, and the selectivity of etching are determined. T he feasibility of manufacturing polyimide track membranes with either cylindrical or conical pores is demonstrated.
