摘要：
A new method is proposed for the synthesis of anisotropic membranes based on F-4SF films, which ensures their modification with polyaniline in a layer with a fixed thickness. The concentration dependences of conductivity and diffusion permeability of the composite membranes are studied. These parameters decrease with increasing thickness of the polyaniline-modified layer. The quantitative correlation is revealed between the regularities of variations in both transport characteristics and the thickness of the modified layer. The absence of the asymmetry of the diffusion permeability of the examined composite membranes is explained in terms of the model of a charged bilayer membrane.
