Structure and Hemocompatibility of Titanium Oxide Films Synthesized by Continuous or Pulsed DC Magnetron Sputtering
Titanium oxide films were prepared by reactive magnetron sputtering using continuous or pulsed DC sputtering power. The results of the structure and vitro hemocompatibility analyses indicated that non-stoichiometric titanium oxide films possess better hemocompatibility than LTIC and that the hemocompatibility of the titanium oxide films are evidently improved with the increase of rutile phase. This can result from the lower interface tension between titanium oxide films and biological substances and lower ratio of dispersive and polar component of the surface energy.
