摘要
以羟丙基甲基纤维素(hydroxypropylmethyl cellulose,HPMC)水凝胶作为模板合成了羟基磷灰石.利用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)和傅里叶变换红外光谱(FTIR)等检测手段对所得的产物进行了形貌与结构表征.结果表明:HPMC水凝胶模板可以诱导羟基磷灰石的形成;模板分子上的多羟基与磷灰石晶体有一定的相互作用,模板的疏水微区和凝胶网络结构为磷灰石的形成提供了微环境,也决定着磷灰石晶体的微观形貌.
Hydroxyapatite （HA）was synthesized in hydrogel of hydroxypropylmethyl cellulose（HPMC）used as template. X-ray diffraction （XRD）, scanning electron microscope （SEM） and Fourier transform infrared （FTIR） spectroscopy were employed to investigate the morphology and structure of the products. The results show that HPMC hydrogel can induce the formation of HA. Polyhydroxy functionalities on the template may associate with HA, while the hydrophobic micro-region and the network structure in the hydrogel provide the microenvironment for the growth of HA and determine the morphology of the crystals.
