Ai. Vilenskii et al., HIGH-ENERGY ION TRACKS IN POLYIMIDE .2. TRACK ETCHING - PREPARATION OF POLYIMIDE TRACK MEMBRANES, High energy chemistry, 28(5), 1994, pp. 359-362
Chemical etching of high-energy ion tracks in polyimide is discussed.
The characteristics of etching with various known etching reagents are
compared. A new reagent, concentrated hydrogen peroxide, that ensures
high selectivity and a sufficient rate of etching is proposed. This e
tching reagent is readily available and environmentally safe. Polyimid
e track membranes for ultra- and microfiltration are prepared.
