There is currently an increasing interest in the use of DLC (diamond like carbon) films in biomedical applications. These investigations making use of DLC in the biomedical area indicate its attractive properties. In this study, we succeeded in depositing DLC on polymer substrates and found the best conditions and method for this application. We evaluated the blood compatibility of polycarbonate substrates coated by DLC (PC-DLC) under different conditions by using epifluorescent video microscopy (EVM) combined with a parallel plate flow chamber.

Due to the attractive properties, diamond-like amorphous carbon (DLC) films have been developed as resist material for photo lithography and as hard coatings. For these applications flat surfaces are required. In this work, the surface morphology and the deposition mechanism of DLC films have been investigated. Using parallel plate r.f. plasma glow discharge, methane gas was decomposed for deposition of DLC films on the third electrode located perpendicularly to the two parallel plates.
