    An original method of obtaining cation exchange composite heterogeneous membranes involving the low-temperature ion-plasma pretreatment of fibrous systems is proposed. The membranes are obtained by the polycondensation filling of polymer composites via the synthesis and hardening of a strongly acidic sulfo cation exchanger on the surface and in the structure of a novolac phenol-formaldehyde fibrous system. The effect of low-temperature ion-plasma pretreatment on a change in the hydrophilicity, capillarity, and structure of heterogeneous cation exchange composite materials Polykon is investigated.
