Abstract

A process for making a functionalized hollow body includes: providing a hollow body including a wall which at least partially surrounds an interior volume of the hollow body, the wall including a layer of glass and having a wall surface with a surface region; at least partially superimposing the layer of glass in the surface region with a functionalizing composition precursor on a side of the layer of glass which faces away from the interior volume, the functionalizing composition precursor including one or more siloxanes; and at least partially contacting the functionalizing composition precursor with a plasma, thereby obtaining the functionalized hollow body including a functionalizing composition which at least partially superimposes the layer of glass in the surface region on the side of the layer of glass which faces away from the interior volume.
