英文摘要Highly ordered hierarchical calcium carbonate is an important phase involved calcification by a wide variety of invertebrate organisms, and its formation is of technological interest in the development of functional materials. in this article, porous caco3 hierarchical microspheres with a hedgehoglike appearance have been fabricated on the flexible substrate under mild conditions. there are two points that play important roles in the regular organization of the terminal products: one is the biphase interfaces, which are generated by organic solvent n-hexane and an aqueous saturated solution of ca(oh)(2), and the other is hydroxyl-terminated monolayers assembled on the flexible pet (poly(ethylene terephthalate)) substrate. the sem images show that novel caco3 hierarchical microspheres consist of densely stacked "shuttles" by the oriented self-organization or caco3 nanoparticles. the ir and xrd spectra indicate that the as-synthesized products are composed of a calcite phase obtained by an acc (amorphous calcium carbonate)to-calcite transformation. in view of the results, a nanoparticle-mediated self-organization process induced by biphase interfaces and sams template is proposed for the integration of functional materials and nanodevices.
