摘要: Nanoparticles of hydroxyapatite(HAP), strontium half substituted hydroxyapatite (SrCaHAP) and totally (SrHAP) were prepared by sol-gel-supercritical fluid drying (SCFD) method. The nanoparticles characterized element content analysis, FT-IR, XRD TEM, the effects substitution on crystal structure, crystallinity, particle shape antibacterial properties Escherichia coli, Staphylococcus aureus, Lactobacillus researched. Results show that can substitute for calcium enter structure apatite according to initial atomic ratios Sr/[Sr+Ca] as 0.5, 1. decreases IR wavenumbers SrCaHAP SrHAP, changes morphology from short rod shaped HAP needle SrCaHAP, back SrHAP. crystallinity is higher than but lower Moreover, property SrHAP are improved after strontium.
