Bioactive and Stability of Calcium Phosphate-Polypyrrole Composite Coatings by Electrochemical Deposition

摘要：

　　This study examined the bioactive and stability of calcium phosphate-polypyrrole(ppy) composite coatings on titanium alloys by electrochemically deposition in simulated body fluid (SBF).Change of coatings mass and SBF pH during coatings soaked in SBF indicated that ppy reduces the decomposition of coatings.The surface morphology of coatings characterized by SEM showed that the stability of composition coating was superior to that of single coating.XRD indicated that ppy induces CO32-enter calcium phosphate coating,which showed that the composite coatings possess better bioactive.Thus,this electrochemical deposition provides an effective method of ppy incorporation at physiological temperature,which can offer excellent bioactive and stability of coatings,with a potential for sustained release of therapeutic agents as required for metallic implant fixation.
