Layout of DBD plasma sources and optimization of gas routing (OGADBD)
Dielectric impeded discharges under atmospheric pressure have been commonly used industrially since the 1970s for the pretreatment (activation) of plastic films. Processes that operate under low-oxygen conditions have also been offered since a few years. There is an important trend towards multifunctional surfaces that can be realized through the use of thin films. A significant need for further research remains here in view of reducing the process costs caused by high chemical consumption.
Within the scope of the AiF/DFG research cluster OGAPLAS for the Optimization of Gas utilisation with Atmospheric pressure PLASma processes, a fundamental study of various atmospheric plasma processes was conducted in order to support the further spread of this technology and increase the associated market opportunities.
The influence of gas flow and precursor supply on the precipitation of chemically reactive surfaces was researched in the course of a sub-project at Fraunhofer IST.
The IGF project 17465N / 1 of the Deutsche Gesellschaft für Galvano- und Oberflächentechnik e.V., Itterpark 4, 40710 Hilden/Germany was subsidised by the AiF under the program for the promotion of industrial cooperative research and development (IGF) of the Federal Ministry for Economic Affairs and Energy (BMWi) based on a resolution of the German Bundestag. The approval period was from 1 September 2012 to 31 October 2015. The final project report is available from TIB Hanover or Fraunhofer IST.
