Though seldom noticed, nanometre sized functional coatings are common in everyday life.
They can dramatically change properties such as hardness, conductivity or biocompatibility of
a large substrate. Plasma discharges are an established tool to deposit these coatings.
However, the industrial production process is often merely empirical. The aim of the
SFB-TR 87 is to overcome this “trial and error” principle through the investigation of the
underlying processes from a physical and material scientific point of view.
The project B2 of the SFB investigates multilayer coatings for polymers. The basic idea is to
combine polymer-like sliding layers and hard diamond-like carbon layers to form a multilayer
that is tolerant to elongation. At a later stage, nanoparticles that are synthesized within the
plasma shall be incorporated in the coating.
