In Situ Synthesis and Characterization of Nanosize Hydroxyapatite/Polyacrylonitrile Composite Bead

摘要：

　　Nano-size hydroxyapatite/polyacrylonitrile composite bead was prepared via in-situ synthesis method.Fourier transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM),particle size measurement and X-ray diffraction (XRD) were used to characterize the HAp/PAN composite bead.XRD curve indicates low crystallinity of HAp.Particle size and SEM analysis demonstrates that decreased partical size of synthesized HAp as well as good distribution with the addition of PAN is found.The HAp is well-distributed and the combination between HAp and PAN is well.FTIR showed that there was no shift of characteristic peaks of synthesized HAp in PAN,which proves the physical interaction between PAN and HAp.The approximate HAp content of 28.6% calculated from thermal analysis curves means high conversion ratio of HAp.The adsorption amount of cadmium ions onto composite beads is lower than HAp particles.
