具有特殊形貌和层次的微米尺度的无机晶体因其在设计功能材料和器件等领域里的应用而受到了广泛的关注。特别是那些具有花状、叶状和树状等仿生形貌晶体更引起人们重视[1-3]

。本文以聚苯乙烯/有序二氧化硅胶体复合膜作为模版，成功的制备了六角喇叭花状的六氟硅酸钠(SFS)晶体。这种花状晶体在水处理方面有着潜在的应用。

Recently, considerable interests have been focused on the growth of crystalline inorganic structure with specific shapes and hierarchies in micrometer scale for their applications in designing new functional materials and devices in various fields. Especially, the materials with shapes like flowers, trees and leaves attracted more attention for bionic design[1-3]. In the present work, we prepared petunia-like sodium hexafluorosilicate (SFS) flowers via a template method of polyatyrene/silica opal composite film. This kind of material has potential application in water treatment.
