Full Text

The synthesis of a novel zinc doped chitosan-hydroxyapatite (chitosan-HAp) composite was done via in situ co-precipitation method. FTIR results showed that zinc is incorporated into the composite formed and is less crystalline compared to the pure hydroxyapatite (HAp). XRD results obtained showed that the incorporation of zinc into the lattice of the chitosan-HAp led to changes in the crystallinity, crystallite size and lattice constant of the composite material. FESEM images of the samples revealed that the novel material has a morphological features that resemble that of bone mineral.
