Notes:
To create a new material with good biocompatibility and high mechanical strength forartificial organs, titanium (Ti) and segmented polyurethane (SPU) were bonded through3-(trimethoxysilyl) propyl methacrylate (γ-MPS), and specify causes governing the bonding strengthof Ti/γ-MPS/SPU interface. The number of cross-links of SPU and the concentration of activehydroxyl groups on the surface oxide film of Ti were controlled by UV-irradaiton and hydrogenperoxide immersion. The number of cross-links of SPU was measured by differential scanningcalorimetry (DSC) and the concentration of the active hydroxyl groups was also determined using azinc-complex substitution technique. Consequently, Ti/γ-MPS/SPU shear bonding stress wasincreased with the increase of the number of cross-links of SPU. In addition, the increase ofcross-links in SPU also improved the Ti/γ-MPS/SPU shear bonding stress
