摘要:
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.

The invention relates to a method and a device for producing hollow bodies comprising a gas barrier coating, in particular PET containers comprising a coating of polyvinyl alcohol. The hollow bodies are treated in a device for increasing the surface energy of the surface to be coated and then in a coating device and a drier. To improve the gas barrier effect of the gas barrier coating, a multi-stage pre-treatment is disclosed, in which the hollow body is subjected to an electrostatic discharge after the aforementioned treatment for increasing the surface energy.

摘要:
This invention provides a method for the fabrication of surfaces of high surface area ratio on polymeric/plastic materials, and their application in the control of the wetting properties of surfaces, of the transport of liquids on such fabricated surfaces, or of the separation of liquids in microchannels of said surfaces. The fabrication of surfaces of high surface area ratio comprises the following steps: (a) selection of a polymer/plastic layer which contains two or more components differing in their plasma etching behaviour (b) exposure of said polymer/plastic layer to an etching plasma to provide selective removal of one polymer component versus a second plasma-resistant component so as to result in a randomly rough columnar-like surface. In addition, exposure of the said surface to an oxidizing plasma or to a fluorocarbon. depositing plasma renders the surface fully hydrophilic or en super-hydrophobic, respectively.
