Abstract

ABSTRACT
A new polymerized organic-inorganic complexation route was used in the synthesis of hydroxyapatite (HAp). A simple structure and inexpensive polymer, polyvinyl alcohol (PVAL), was used as the organic carrier for precursor ceramic gel. Hydroxyapatite – polyvinyl alcohol –gel nanocomposite was synthesized and characterized via FTIR, SEM and XRD. The effect of pH on the synthesis of hydroxyapatite was studied by FTIR and SEM analyses of the synthetic powder to achieve apatite form. The PVAL content and its degree of polymerization had a significant influence on the homogeneity of hydroxyapatite gelatin nanocomposites. Various calcium phosphates structures were achieved by controlled pH values.
