Process for the surface modification of a polymer substrate by formation of nanopillars

Processus de modification de surface d'un substrat polymère par formation de nanopiliers

Résumé

The present invention relates to a process for the surface modification of a polymer substrate comprising:- a step for contacting a solution with the surface of a substrate made of a polymer A, said solution comprising a solvent S and a polymer B, whereby a ternary blend comprising the solvent S, the polymer A, and the polymer B is obtained, and is present on top of the surface of the polymeric substrate,- a step for eliminating the solvent S from the ternary blend as obtained above, whereby the surface of the polymer substrate is modified and is made of a micro-phased mixture of polymer A and of polymer B, and- a step for eliminating the polymer B, in order to obtain a modified polymer substrate having nanopillars at its surface.
