Size-Controlled Hydroxyapatite Nanoparticles as Self-Organized Organic-Inorganic Composite Materials

Sodium salt carboxymethyl cellulose (CMC) was used to prepare HAp-CMC composites through co-precipitation process. HAp nanorods with well controlled particle size were welll aligned along the c axis in the final composites. TEM, XRD, FTIR analysis were used to characterized the samples. It was found that the carboxyl groups in cellulose might be the main guiding site for the precipitation and growth of HAp and the formation of the resulting composites.
