Abstract

Imprinted polymers were prepared from divinylbenzene and 6-methacrylamidohexanoic acid as the functional monomer, using calcite crystals of three different morphologies as templates. After template removal voids in the polymer remained which reflected the size and shape of the template crystals. The use of these imprinted polymers in aqueous supersaturated calcium carbonate solution resulted in the formation of some crystal objects of unusual morphology. In the case of spheroidal imprints, the nucleated crystals grow via the {104} faces in many directions creating clusters whose surface consists of many small rhombohedral crystallites. However, in the case of rhombohedral imprints, no conflict between crystal growth and the constraints of nucleation at the polymer surface arises and the new crystals very closely resemble the templates. © 2001 Society of Chemical Industry
