NANOSIEVE COMPOSITE MEMBRANE

摘要

The invention is directed to a nanosieve composite and a method for preparing a nanosieve composite membrane. The nanosieve composite of the invention comprises - an inorganic nanosieve layer having an average pore diameter of 200 nm or less, and - two or more porous layers having an average pore diameter of mm or more, wherein at least one porous layer is at a first side of said inorganic nanosieve layer and at least one porous layer is at a second side of said inorganic nanosieve layer.
