Platelet Adhesion on Titania Film Prepared from Interaction of Ni-Ti Alloy with Hydrogen Peroxide Solution

摘要

Titania films were prepared from interaction of Ni-Ti shape memory alloy with hydrogen peroxide solution followed by heating at 400"C. The titania films consisted of crystalline phase of TiO2 (anatase). Them vitro platelet adhesion property of the titania films was examined. The titania films on Ni-Ti alloy substrates adhered less platelets than Ni-Ti alloy substrate without treatment. This indicates that the titania film can suppress the adhesion of platelet. The present chemical modification process with hydrogen peroxide solution is applicable to prevent the Ni-Ti shape memory alloy materials from platelet adhesion when in contact with blood.
