Synthesis of Diamond-Like-Carbon Films as the Coating Prototype for Biomedical Materials
Synthesis of Diamond-Like-Carbon (DLC) films as the coating prototype for biomedical materials was fabricated by direct current (DC) magnetron sputtering at working pressure of 1.0x10-3 Torr, DC power between 50-150 W, and coating time between 60-180 sec. Polystyrene and Graphite were used as a substrate and target, respectively. The results showed that the surface roughness increased with increasing of the power and the coating time. These changes influenced the contact angle of DLC films, and the time of blood clotting. Blood clotting time of the blood samples with the fabricated surface was faster than that of the blood samples without the surfaces.
