Abstract

The object of the invention is to provide a surface treatment process which enables a substrate (polymer) to be given specific physical properties, especially surface nanoporosity, for example with a view to electroless metallizing it, and which completely replaces surface treatment by sulphochromic pickling. To achieve this objective, the surface treatment according to the invention comprises a hybrid UV / corona treatment of the substrate surface followed by electroless metallization. The invention also relates to a device for implementing these processes.

Description

technical field [0001] The technical field of the invention is the surface treatment of polymer or copolymer such as ABS (acrylonitrile-butadiene-styrene) substrates, in particular for covering said substrates with a metal film. [0002] The invention also relates to a process for the electroless metallization of substrates for decoration, such as chrome plating of automotive or aerospace parts. The invention also relates to the electroless metallization of substrates for electronic devices, in particular for the production of conductive paths. Background technique [0003] technical problem [0004] In the field of electroless metallization of polymer substrates (such as ABS), pretreatment of the substrate surface is required to facilitate the adhesion of the metal film. [0005] The most commonly used pretreatment is a chemical surface oxidation treatment utilizing sulfochromic attack, as described inter alia in US-B-3769061 , GB-A-1240294 and GB-A-1291351. This strong ...
