Controlled radical assisted polymerization

摘要

The present invention is directed to a method of forming a polymer coating on a substrate. The method comprising the steps of providing in an evacuated reaction chamber a substrate having a surface to be coated; and providing a first source of polymer forming material and a second source of radicals. According to the invention the first source and the second source are separated from each other and from the reaction chamber, and the polymer forming material as well as the radicals are, at least temporarily, conducted contemporaneously but spatially separated to the substrate's surface, so that a reaction of the polymer forming material with the radicals is avoided before they reach the substrate's surface. Further, the present invention is directed to a device for carrying out the method according to the invention.

1. A device for forming a polymer coating on a surface of the substrate, said device comprising:
a reaction chamber for accommodating the substrate to be coated; a first source for providing polymer forming material; a second source for providing radicals; a conduit system structured and operable to contemporaneously and spatially separately conduct the polymer forming material and the radicals respectively from the first and second sources to a surface of the substrate to be coated, such that a reaction of the polymer forming material and the radicals is avoided before polymer forming material and the radicals reach the surface of the substrate, wherein the conduit system comprises a first conduit means fluidly separated from a second conduit means, wherein the first conduit means comprises a first comb-shaped member having a plurality of first parallel, hollow teeth, and wherein the second conduit means comprises a second comb-shaped member having a plurality of second parallel, hollow teeth, where the teeth of the first and second comb-shaped members engage one another, and wherein the teeth of the first comb-shaped member comprise a plurality of first outlets and the teeth of the second comb-shaped member comprise a plurality of second outlets.
