摘要
Biomimetic BaCO3 materials with various morphologies have been synthesized in a cationic polyelectrolyte-controlled mineral solution. Investigations showed that the mineral solution initially underwent a phase separation to produce a condensed liquidlike amorphous intermediate. This mineral solution was a typical reaction-diffusion field, in which concentric ring patterns were frequently observed. Subsequently, overgrowth fibers were seen growing on large microspheres and their growth could be interpreted in terms of a mesocrystal self-assembly process. This work opens up the possibility of using positively charged polyelectrolytes to design a very wide range of inorganic materials.
