摘    要:
以嵌段共聚物P123(聚环氧乙烷-聚环氧丙烷-聚环氧乙烷,平均分子量5 800)为模板,在水热条件下,进行了SrCO3的合成,获得了不同形貌的SrCO3聚集体.用粉末X-射线衍射(XRD)和扫描电子显微镜(SEM)等仪器对所制备产物的结构和形貌进行表征.在不同的制备条件下,分别得到了棒束状、树枝状、麦穗状SrCO3和由麦穗状SrCO3结构组装成的空心球聚集体,对P123的作用和聚集体形成的机理进行了初步探讨.

关 键 词:P123  SrCO3  水热法  聚集体结构

Abstract:
Particles of strontium carbonate with different morphologies were prepared by a facile hydrothermal process in the presence of P123.The as-prepared products were characterized with X-ray diffraction(XRD) and scanning electron microscopy(SEM).The results show that SrCO3 particles of various shapes such as bundle,dendritical,wheatear-like and hollow sphere can be obtained by varying concentration of P123 and hydrothermal temperature.The formation mechanism of SrCO3 nanostructures is discussed.
Keywords:P_(123)  SrCO_3  P_(123)  SrCO_3  hydrothermal method  aggregate structure
