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 SrCO₃nanostructures is discussed.

Key words: P₁₂₃; SrCO₃; hydrothermal method; aggregate structure
