摘要：

A study of the properties of thermoradiationally modified polytetrafluoroethylene and its importance for use as the basis of polymer membranes is presented. The hydrogen permeability of a TRM-PTFE film was studied in comparison with an original PTFE film, and showed a three-fold decrease in hydrogen permeability. Further, TRM-PTFE films were irradiated with accelerated Xe ions with an energy of 1 MeV with fluences from 1 x 10(8) to 1 x 10(11). The changes induced by ion treatment were analyzed by infrared spectroscopy of disturbed total internal reflection (IR-ATR) and by atomic force microscopy (ASM). IR-ATR indicated the absence of destruction in the fluence range from 1 x 10(8) to 3 x 10(10) cm(-2) (in the area of isolated tracks) and the beginning of overlap of latent tracks on fluences from 3 x 10(10) to 1 x 10(11) cm(-2). Topographic images with AFM showed layered lamellar structures that collapsed at a fluence of 10(8) cm(-2). The destruction was accompanied by a decrease in roughness about seven times the size of the track core observed by the ASM method, fully corresponding to the value obtained on the basis of calculations using modeling in an SRIM program.
