Effects of macromolecules on the crystallization of CaCO3 the Formation of Organic/Inorganic Composites
The effects of macromolecules as soluble additives and solid matrices have been examined for the crystallization of CaCO3. A vaterite form grows on a glass substrate in the presence of poly(glutamic acid) (PGA) containing a carboxylic acid group as a soluble additive. In contrast, no crystal growth has been observed when poly(acrylic acid) (PAA) exists as an additive though it has the same functional group. The conformation or the backbone structure of the polymers may have an influence on the crystal polymorph of CaCO3. Thin film states of CaCO3 crystals have been obtained as organic/inorganic composites with chitosan that acts as a solid matrix in the presence of PAA or PGA as a soluble additive.
