羟基磷灰石(HAp)是一种与人体骨骼成分类似的无机材料,具有良好的生物相容性.本文以氧化石墨烯(GO)为模板,通过模拟体液(SBF)仿生矿化原位合成了 HAp纳米粒子.通过SEM、XRD、EDS和拉曼光谱等测试分析研究了矿化时间、SBF/GO体积比对矿化产物物相组成、形貌和结构的影响.结果表明,矿化处理后的GO表面形成了大量均匀分布的类骨HAp.随着矿化时间延长和SBF体积占比增大,矿化产物的尺寸及数量增大,GO层间距逐渐扩大.本研究验证了 GO辅助合成HAp的可行性,拓展了仿生矿化法的应用领域.
In-Situ Synthesis of Hydroxyapatite by Biomimetic Mineralization Assisted by Graphene Oxide
Hydroxyapatite(HAp)is an inorganic material similar to human bone,with good biocompatibility.In this paper,HAp nanoparticles were in-situ synthesized using simulated body fluid(SBF)biomimetic mineralization method with graphene oxide(GO)as a template.The effects of mineralization time and volume ratio of SBF to GO on the phase composition,morphology,and structure of mineralization products were studied through testing and analysis of SEM,XRD,EDS and Raman spectroscopy.The results show that a large amount of uniformly distributed bone-like HAp is formed on the surface of GO after mineralization treatment.With the extension of mineralization time and the increase of volume proportion of SBF,the size and quantity of mineralization products increase,and the interlayer spacing of GO gradually expands.This study verifies the feasibility of synthesis of HAp nanoparticles assisted by graphene oxide,and expands the application field of biomimetic mineralization method.
