Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a method for plating the surface of polymer materials with a metal film by treating the surface of polymer materials with cold plasma method to introduce hydrophilic fuctional groups and then plating the surface of polymer materials with a metal film according to the electroless plating method. Wherein said method is characterized in that the cold plasma treatment reduces the contact angle of the surface of polymer materials to water by 5 to 60~. Further in said method the surface of polymer materials can be more efficiently plated with the metal film by aditionally practicing the step either of immersing the polymer material into an organic solvent …

Why it's free to use
- Filed March 6, 2002 and granted May 10, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 6, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 6, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
