A method and a series of devices for dry cleaning, activating, modifying, coating, and biologically decontaminating (degerming, disinfecting, sterilizing) surfaces by means of an atmospheric pressure plasma generated using a surface barrier discharge are provided. The invention is used for dry cleaning, activating, coating, modifying, and biologically contaminating surfaces by means of an atmospheric pressure plasma generated in a defined, flowing gas atmosphere by a surface barrier discharge, comprising a high-voltage electrode that is covered with a dielectric or ferroelectric material, an electrically conducting grounded contact electrode, a high-voltage supply, a gas supply, and a gas nozzle (encompassing a gas outlet); said gas nozzle is located in the direct vicinity of the grounded contact electrode, is integrated into the contact electrode, or acts as the grounded contact electrode.

Method and device for plasma-supported surface treatment

The invention relates to a method for coating surfaces with micro- and nanoparticles, the micro- and nanoparticles being chemically bonded to the surface, comprising the steps of pre-treatment of the surface with a plasma method, simultaneous or subsequent application of the micro- and nanoparticles to the surface, and subsequent fixation of the micro and nanoparticles on the surface using a plasma method, characterized in that the fixation of the micro- and nanoparticles takes place with the aid of anisothermal plasmas, the median electrical energy of which lies in the range of the bond dissociation energy of the micro- and nanoparticles, thus allowing the strength of the chemical bond between the surface and the micro- and nanoparticles to be variably set.
