Coatings on Polymers and Composite materials

Surface modification of polymers is very important to improve adhesion; to increase their surface energy or modify the functional groups on the polymer surface to make them more amenable to adhesive bonding to another polymer, inorganic material or to a m0etal. In comparison with other methods of modifying polymer surfaces, such as wet-chemical or mechanical treatments, exposure to flames, UV radiation, corona discharges, ion beams, and intermediate adhesive layers, high-vacuum plasma modification is very powerful, since it can address all of the adhesion mechanisms.

Polymer/metal or polymer/oxide multilayer stack structures have a wide range of optical, packaging, semiconductor, and display applications. A primary concern in the deposition of such stacks is adhesion at polymer–substrate, polymer–metal and metal–polymer interfaces. The substrate surface must be sufficiently activated to promote an interaction with the depositing metal atoms. By removing surface contaminants, incorporating new and more reactive functional groups, and cross-linking weak subsurface layers, low-temperature plasma has proven to be very efficient for such applications. In addition, the plasma process is fully compatible with all other vacuum technologies, allowing in-line and high-speed processing of polymer/metal multilayer structures.

The Centre for Plasma Technologies – Plasma D.O.O has been involved in many projects for coating of variety of polymer substrates/parts for different purposes and applications. Some of them are:
