Deposition of amorphous calcium carbonate hemispheres on substrates

Abstract

The amorphous calcium carbonate (ACC) hemispheres were deposited on the mica and poly(diallyldimethylammonium chloride) modified surface. The form of the ACC deposit on the substrates can be controlled by modifying the substrate surface, the introduction of additives, or both. It demonstrated that substrates (insoluble matrix) and additives (soluble macromolecules) have significant influence on the crystallization of CaCO3.
