Flexible nano coatings

We are investigating gas phase and surface processes relevant for plasma coating and etching processes. Thorough understanding of the energetic processes enables us to tailor functionalized surfaces considering the flexibility and surface of substrates such as fibers, textiles, membranes etc.

Requirements for applications in aqueous environments are met by our high performing and permanent plasma coatings, also regarding the interaction of water with the surface and sub-surface (bioresponse, corrosion, wettability, adhesion, defined degradability etc.).

Our knowledge extends to the successful transfer of plasma processes (etching, cleaning, plasma polymerization, sputtering) to industry supported by pilot-plant reactors both for web and fiber coating including cost models.

- Deposition of plasma coatings with film properties such as hydrophilic/

hydrophobic, antimicrobial, antistatic, conductive, permanence and washing fastness, friction-reducing etc. without influencing the substrate (e.g. textile) properties.

- Formation of vertical chemical gradient films through variation of plasma conditions during deposition reducing aging effects, improving adhesion and affecting protein adsorption.

- Etching processes on polymers exposing embedded structures to the surface or widening pores.

- Development and modification of plasma reactors supporting the optimization of plasma processes, also regarding scalability. By using pilot-plant reactors the conditions for the transfer of plasma processes into industry are examined.
