Colloidal nanoparticles based on strontium carbonate (SrCO3) have been developed through biomineralization-inspired approaches utilizing an amorphous precursor stabilized by water-soluble acidic polymers. Amorphous states stabilized by acidic polymers gradually crystallize in aqueous solutions, leading to the formation of nanorods with a narrow size distribution. The size of nanorods was estimated to be several hundred nanometers in length and around 100 nanometers in width. Thesenanorods exhibit liquid crystalline (LC) phases in aqueous dispersion states at a certain range of the concentration. Size of SrCO3 nanorods was tuned by the change of crystallization condition for theenhancement of dynamic properties of LC SrCO3 materials.
