Abstract

An organo-mineral composite (OMC) based on calcium hydroxyapatite Ca10(PO4)6(OH)2 (HAp)
and natural biopolymer methylcellulose [C6H7O2(OH)3-x(OCH3)x]n (MCel) was synthesized by
coprecipitation from water solution in the system Ca(OH)2–H3PO4–[C6H7O2(OH)3-x(OCH3)x]n–H2O at
37°C. Composition and structure of the OMC and HAp crystallographic characteristics and sizes of HAp
nanoparticles were determined by XRD analysis, FTIR spectroscopy, scanning and transmission electron
microscopy and electron diffraction method. Formation of HAp nanoparticles agglomerates with sizes
about 150 nm lengthwise and 30 nm across has been established. Conclusion about interaction between
HAp nanoparticles and methylcellulose supermolecules was made
