NUCLEATION AND SELECTIVE GROWTH OFPOLYMORPHS OF CALCIUM CARBONATE ON ORGANIC-INORGANIC HYBRID FILMS

Inorganic/organic ternary hybrid films that are constituted of gelatin (G), poly(monomethyl itaconate) (PMMI) and silica (Si0(2)), are used as a solid matrix to study the crystalization of calcium carbonate (CaC0(3)). These films are transparent and stable in aqueous solutions due to the formation o...
