<p>A surface region, including at least one polymer, of an article is treated by placing the article into a closed reaction chamber (12) which is evacuated (60, 65) to a negative pressure. After evacuation, a treatment gas, comprising one or more components which are reactive with said surface, is rapidly injected (35, 30, 40, 50) into the reaction chamber (12). The treatment gas is allowed to react with the articles within the closed reaction chamber (12) for a predetermined period of time. The treatment gas is then removed (60, 65) from within the reaction chamber (12) and can be replaced (33, 55, 37, 50) with an inert gas at about atmospheric pressure. <IMAGE></p> |
