FRACTAL APPROACH TO PENETRATION CHARACTERISTICS DESCRIPTION OF POLYMERIC COMPO- SITE MEMBRANES
The paper presents the results of the analysis of the structural organization of porous space in composite reverse osmosis MGA-95 and ESPA membranes. A capillary model and model of the laid spheres are considered. Special procedure of reorganization of a low angle x-ray dispersion curve allows analyzing disseminating objects as a set of monodisperse formations of spherical, disk-shaped and cylindrical forms. Using approach of Gine for certain vectors of dispersion average radiuses of inertia of disseminating elements have been defined. The structural organization of membranes pores taking into account their polydisperse character was considered in the light of self-affine fractal conception.
