1. A method for treating a polymer part, which is a method for modifying the roughness of a surface of said polymer part and for functionalising said polymer part, comprising:
a step of contacting the polymer part with vapours of solvent(s), capable of at least partly solubilising said polymer part, the contacting step being carried out under vacuum, and
before the contacting step or after the contacting step, a step of depositing at least one functionalising material over all or part of the polymer part, the functionalising material(s) being electrically conductive polymers and/or organophosphorus polymers.
