Abstract

The paper presents the results of a study of the surface and optical properties of the PM-1 polyimide film and the polyimide track membrane. For the study, polyimide (track) nuclear membranes manufactured by ION TRACK TECHNOLOGY FOR INNOVATIVE PRODUCT (it4ip, Belgium)) is used. The pore diameter is 200 nm, the pore density is 5 • 108 cm-1, and the thickness of the polyimide membrane is 25 μm. The data of IR spectroscopy are presented. It is shown that the decrease in the intensity of the peaks of the IR spectra of the membrane compared to the film is a consequence of the oxidative degradation of the polyimide after exposure to heavy ions and chemical etching. The data on the effects of heavy ion irradiation and chemical etching of a polyimide film to obtain a membrane on surface hydrophobicity / hydrophilicity are presented. The optical density of the film and track membranes is determined in the wavelength range of 350-950 nm. The optical density is measured in increments of 50 nm. It is shown that despite the strong difference in the spectral dependence of the optical density of the polyimide film and the track membrane, the optical density of the PM-1 film and the track membrane is quite low in the entire studied wavelength range and does not exceed 0.26 and 0.42, respectively.
