Hierarchical structures of self-assembled hybrid calcium carbonate: nucleation kinetic studies on biomineralization

摘要

A novel CaCO3 hybrid material with a well-ordered hierarchical structure was synthesized under the effects of phosvitin. Kinetic experiments demonstrate that phosvitin suppresses the supersaturation-driven interfacial structure mismatch between CaCO3 crystallite and substrate, and promotes the formation of oriented CaCO3 nanocrystallite assemblies at low supersaturations.
