Biomimetic Synthesis of CaCO3 Particles with Specific Size and Morphology

Abstract:

Article Preview

Calcium carbonate particles with different morphologies were fabricated by the precipitation reaction of sodium carbonate with calcium chloride in the absence and presence of the copolymer poly(styrene-alt-maleic acid) (PSMA) at 80oC, respectively. The as-prepared products were characterizedwith SEM, XRD, Infrared and BET surface areas. The results showed that the pH of solution and the concentration of PSMA and CaCO3 significantly influenced the morphologies of CaCO3 particles. Various crystal morphologies of calcium carbonate, such as plates, rhombohedras, rods, ellipsoids, dumbbells, peanuts, spheres etc., could be obtained depending on the experimental conditions.
