Abstract: A method for depositing functional groups on a surface of an object, and to the object treated as such, by generating and maintaining a plasma, bringing the object surface close to or in a space between the plasma electrodes, an atmosphere being present between the two electrodes, and depositing a plurality of functional groups on at least part of the surface of the object, wherein the atmosphere between the two electrodes comprises a multi-functional hyperbranched compound which is a polymer based on ABm type monomers, or a derivative of such polymer, wherein m is at least 2, A and B have reactive functional groups selected such that group A is reacted at least m times with group B, and the hyperbranched compound has a degree of branching (DB) in the range of 10.0-99.9%.

Abstract: Provided herein are processes for depositing a plasma coating on a substrate and coated substrates obtained thereby. More particularly, processes for characterizing a plasma coating on a substrate are provided. The process for depositing a plasma coating includes the step of exposing the substrate to a plasma. The plasma includes at least one coating precursor and one fluorophore other than the coating precursor.

Abstract: A method for applying a hydrophilic coating on a substrate includes: providing a substrate (1), producing an atmospheric pressure plasma discharge in the presence of a gas, at least partially exposing the substrate to the atmospheric pressure plasma discharge. The method introduces a liquid aerosol (6) or a vapor of coating forming material into the atmospheric pressure plasma discharge, thereby forming a coating on the substrate. The coating forming material is a non-polymerizable acetate derivative, and is ethyl acetate in one embodiment.
