The formation of bonelike apatite on synthetic polymers coated with titanium oxide was investigated. Plate specimens of polyethylene (PE) poly(ethylene terepthalate) (PET), ethylene-vinyl copolymer (EVOH) and Nylon 6 were prepared by compression molding. Surface changes on the specimens were investigated before and after soaking in simulated body fluids (SBF) using XRD, FE-SEM, EDX and XPS. The results show that TiO2 coatings could be achieved on PE, PET, EVOH and Nylon 6 without silane-coupling treatments by a sol-gel dipping technique, and that the polymer substrates induced the nucleation and growth of a bonelike apatite layer on the specimen surfaces in SBF within 7 days.
