METHOD OF NANO-MODIFICATION OF SYNTHETIC POLYMER MEMBRANES

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of composite membranes for membrane separation of fluids and gases with selective layer containing multilayer carbon nanotubes. Proposed method comprises formation of carbon nanomembrane selective layer on polymer microporous substrate with the help of ultrasound disperser and drying. Carbon nanotubes 6-8mcm-thick selective layer and solvent composed of stable colloidal solvent mix is formed by forcing 0.005-0.1%-solution of said mix through aforesaid substrate at preset pressure to preset selectivity.EFFECT: preset selectivity and permeability for membrane treatment of various media.4 cl, 1 tbl, 3 ex
