Investigation on Modulation of Sodium Polyacrylate to Biomineralization of Titanium Implants
聚丙烯酸钠对钛基种植体仿生矿化性能的调控作用研究

Microarc oxidation (MAO) technique was applied for the formation of ceramic coating on titanium surfaces, and the modulating mechanism of sodium polyacrylate to crystal growth was studied by SEM, XRD and FT-IR in the biomineralization. Results show that the crystal size of HCA is reduced when specimen is bio-mineralized with the addition of sodium polyacrylate. Meanwhile, the morphology of crystal is changed and the density of mineralization layer is increased when sodium polyacrylate is applied.
