Abstract
Gas-separation membranes were prepared by the oxidative polymerization of aniline carried out in situ on porous polyethylene films. Polyaniline layers were shown to have good adhesion to the porous support. The thickness and homogeneity of polyaniline layers in composite membranes were estimated by UV spectroscopy and scanning electron microscopy. Permeability, selectivity, and diffusion and sorption coefficients in relation to the doping degree of polyaniline were measured for a number of gases. The effects of diffusion and sorption on the transport characteristics of the above membranes were analyzed. Changes in the gas-permeability and selectivity of membranes in the course of dedoping-redoping of polyaniline were studied.
