Abstract

So far, the pore architecture in biomaterials plays a critical role on the cell response and integration between the biomaterials and implanted environment. In this study, porous calcium phosphate (CaP) coatings and CaP/protein composite coatings have been successfully constructed on titanium substrate by using an electrochemically induced deposition technique. The shape, size and pliability of CaP crystals are controlled by electrolyte concentration, temperature, current density, time and protein additive in preparing process. In addition, the formation mechanism of the porous structure is discussed based on the “hydrogen bubble template” model. It demonstrates that the growth velocity of CaP crystals should match well with the forming-disappearing velocity of hydrogen bubble, and the pliability of the CaP crystals should fit with soft bubble. As a result, dynamic hydrogen bubble can act as an effective template to construct the nano-micro porous structured biomaterials coatings by controlling the growth velocity of CaP crystals.
