The synthesis of bilayer materials with porous upper layers composed of PVC hydroxyethylcyclam derivatives filled with carbon and a layer consisting of hydroxyethylcyclam, cross-linked via Si–O–C groups with the silica chains of a developed surface of asbestos fabric, is described. The aza-crown groups in these materials are bound with aqua complexes of H 2 SO 4 or NaOH. The structure of the materials is examined, their adsorption characteristics are determined, and the rate of motion of H + or OH – ions in electrochemical bridges is measured, while the formation of H 2 and O 2 in their cathodic and anodic polarization is determined as a function of voltage. It is shown that the upper layer of these materials is adsorption-active and electronand H + - or OH – - conductive, while the bottom layer is only H + - or OH – - conductive; through it, the upper layer is supplied with the H + or OH – ions needed for the regeneration of the aqua complexes broken down to H 2 and O 2 on carbon particles.
