Synthetic organic polymers were modified with silane-coupling agents, subsequently, coated with hydrated titania abundant in Ti-OH group, to produce novel materials with bone-bonding property, i.e. bioactivity. Formation of bonelike apatite layer on the modified polymers was examined using a simulated body fluid (SBF). The apatite formation in SBF was induced on the surface of silane-coupled and TiO2-coated substrates, within two days, irrespective of the types of polymers among PET, EVOH, Nylon 6 and Nylon 6/6. Consequently, these surface modifications provide organic polymers with the inductive effect of apatite nucleation in SBF, regardless of their structures or compositions.
