FIELD: process engineering.
SUBSTANCE: invention relates to separation of mixes, particularly, to polymer membranes, their application and production. First said of proposed method comprises producing filler suspension including vitreous polymer solvent and nano particles. Said particles are integrated into aggregates with average size of 50 nm to 200 nm. Second step comprises adding vitreous polymer to filler suspension to make polymer suspension. Then, vitreous polymer is dissolved in polymer suspension. Then, polymer suspension is poured on substrate and solvent is removed. Polymer membrane with filler comprises aggregates of filler nano particles. Said membrane may be used in pervaporation and nano filtration.
EFFECT: improved properties.
