摘要 以聚苯乙烯磺酸钠为有机添加剂,分别在水溶液和二甲亚砜-水溶液体系中,通过混合沉积的方式制备出球形和橄榄形的球霰石材料。获得的产物通过场发射扫描电子显微镜(FESEM)、X-射线衍射(XRD)和傅里叶变换红外光谱(FT-IR)进行了表征。结果表明,球霰石材料的形貌与反应体系存在的DMSO密切相关,且该类材料在室温下较为稳定。这种简易的制备具有不同形貌材料的方法有望为该类材料的制备提供参考途径。 Spherical and olivary vaterite crystals were conveniently fabricated via a simple Mixingprecipitation method in aqueous solution and DMSO-H2 O solution separately,and in the present of poly( sodium-p-styrenesulfonate)( PSS). The obtained samples were characterized by field emission scanning electron microscopy( FESEM),powder X-ray diffractometer( XRD) and Fourier transform infrared spectroscopy( FT-IR). The results indicate that the morphology of vaterite crystals was closely related to the presence of DMSO in reaction system,and this kind of material is stable at ambient condition. This simple fabrication method is hopefully to apply in the preparation of these types of inorganic materials.
