Surface amination of three-dimensional substrates by RotoTEC plasma treatment under defined gas atmospheres at ambient pressure

Surface treatment by an atmospheric-pressure AC corona discharge stabilized by a dielectric barrier under defined gas atmospheres has been investigated for the functionalization of BOPP foil fixed on different three-dimensional substrates of different geometries. The influence of the type of gas atmosphere, discharge gap, and the treatment duration on the surface tension and the surface amination was determined and will be discussed here.
