Abstract:

The preparation and characterization of an inorganic/organic composite scaffold is proposed in this paper. The substrate was realized by the polymerization of an electroconductive polymer, namely polypyrrole PPy, into an hydroxyapatite HAp porous support. The PPy/HAp composite was characterized by XRD, Hg porosimetry measurements, SEM-EDS and electrochemical test. The results pointed out that the PPy polymer entered into the HAp whole pores moving through the interconnected paths of the hydroxyapatite matrix. The PPy thin film doped with heparin maintained its electrochemical characteristics even in the ceramic support.
