Title (EN) NANOSTRUCTURED MEMBRANES AND USES THEREOF
(FR) MEMBRANES NANOSTRUCTUREES ET LEURS UTILISATIONS
Abstract:
(EN) 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.
(FR) La présente invention concerne un procédé de préparation d'une membrane nanostructurée, ledit procédé comprenant les étapes de : i) Irradiation aux ions lourds d'un substrat polymère, ce par quoi des traces latentes du passage d'ions à travers toute l'épaisseur (e) du substrat polymère sont formées; et ii) Révélation chimique partielle desdites traces latentes, ce par quoi on obtient une membrane nanostructurée comprenant : - des nanopores dont la profondeur (p) est inférieure à l'épaisseur du substrat polymère (e); - des traces latentes résiduelles non révélées.
