Abstract

Composite coatings containing brushite (CaHPO₄ • 2H₂O) and chitosan were prepared by electrochemical deposition. The brushite/chitosan composites were converted to hydroxyapatite/chitosan composites in aqueous solutions of sodium hydroxide. The coatings ranged from 1 to 15% chitosan by weight. Qualitative assessment of the coatings showed adhesion signifi cantly improved over that observed for electrodeposited coatings of pure HA.
