FIELD: technology for producing hydrophilic porous membranes with high water penetrability, possible use during separating micro, ultra and hyper filtering processes, during dehydration of moist gases.
SUBSTANCE: porous hydrophilic membrane includes porous inertial substrate on basis of fluorocarbon polymer or perfluorinated polymer, onto which ion meter is applied, representing a fluorinated or perfluorinated polymer, having functional groups -SO3H and/or -COOH. Produced membranes have water penetrability over 1 liter/(hour·m2·athm) and are not subjected to sweating out.
EFFECT: higher efficiency.
