NANOSTRUCTURED MEMBRANES AND USES THEREOF

摘要

The invention relates to a method for producing a nanostructured membrane, comprising the steps of: i) irradiating a polymer substrate with heavy ions such that latent ion tracks are formed through the entire thickness (e) of the polymer substrate; and ii) partially etching said latent tracks so as to obtain a nanostructured membrane comprising nanopores that are less deep (p) than the thickness (e) of the polymer substrate as well as unetched residual latent tracks.
