摘要
To improve the osteointegration property of biomedical titanium,nano-architectured electroactive coating was synthesized through the electrochemical polymerization of dopamine and pyrrole.The highly binding affinity of Ca2t to the catechol moiety of doped dopamine enabled efficient interaction between polypyrrole/polydopamine nanowires and mineral ions.The results indicate that the PPy/PDA nanowires preserved its efficient electro-activity and accelerated the hydroxyapatite deposition in a simulated body fluid.The PPy/PDA nanowires coating could be applied to promote the osteointegration of titanium implant.
