Abstract A potassium titanate biological thin film/titanium alloy biological composite was fabricated by way of bionic chemistry. The biocompatibility in vitro of Ti-15Mo-3Nb and the potassium titanate biological thin film/titanium alloy was studied using simulated body fluid cultivation, kinetic clotting of blood and osteoblast cell cultivation experiments in vitro. By comparing the biological properties of both materials, the following conclusions can be obtained: (1) The deposition of a calcium phosphate layer was not found on the surface of Ti-15Mo-3Nb, so it was bioinert. Because the network of potassium titanate biological thin film could induce the deposition of a calcium phosphate layer, this showed that it had excellent bioactivity. (2) According to the values of kinetic clotting, the blood coagulation time of the potassium titanate biological thin film was more than that of Ti-15Mo-3Nb. It was obvious that the potassium titanate biological thin film possessed good hemocompatibility. (3) The cell compatibility of both materials was very good. However, the growth trend and multiplication of osteoblast cells on the surface of potassium titanate biological thin film was better, which made for the concrescence of wounds during the earlier period. As a result, the potassium titanate biological thin film/titanium alloy showed better biocompatibility and bioactivity.
