Notes:
Electrically conducting polymer containing calcium phosphate coating (ppy/brushite) wasmade on the Ti-6Al-4V surface by means of electrochemically assisted co-precipitation. This studyexamined the effects of the electrically conducting polymer on electrochemically assisted co-precipitationof ppy/ brushite onto titanium alloys. Electrochemically assisted co-precipitation of ppy/ brushite coatingsresulted in an increase in the thickness and adhesion of coatings compared to those of coatings of singlecalcium phosphate at the same deposition conditions. The surface morphology of coatings characterizedby SEM showed that the morphology of ppy/ brushite was superior to that of brushite. XRD indicated thatppy did not change the phase of brushite. Thus, this electrochemically assisted co-precipitation techniqueprovides an effective method of polypyrrole incorporation at physiological temperature, which can offerexcellent thickness, adhesion and structure of coatings, with a potential for sustained release oftherapeutic agents as required for metallic implant fixation
