Abnormal polymorph conversion of calcium carbonate and nano-self-assembly of vaterite by a supported liquid membrane system

This article describes a novel biomimetic strategy for the synthesis of CaCO3 crystals with different structures by a supported liquid membrane containing a mobile carrier, and first reports the abnormal structure conversion of CaCO3 from calcite to vaterite. Furthermore, we found that the sub-micron-sphere vaterite prepared by the supported liquid membrane was a nano-self-assembled system. This kind of vaterite has a bright future for various applications.
