FIELD: nanotechnologies.
SUBSTANCE: invention is related to the field of membrane technology and nanotechnology. Selective nanofilter contains substrate with pores in the form of through holes on the whole surface, and pores are directed along substrate thickness, and active layer, at that substrate thickness is more than active layer thickness. Substrate is made with pore size of 50-100 nm, and active layer represents thin 100-150 nm-thick pore-free film of metal with high selective gas permeability, which is fixed to substrate with pore covering in the latter. Method of manufacture includes preparation of substrate, application of foil layer with applied metal film with selective gas permeability, their welding and foil removal.
EFFECT: invention provides for guaranteed throughput capacity, high strength and reliability.
