Calcium Carbonate Skeletal Material Is Synthesized via Phase Transition of the Calcium Carbonate Cartilaginous Material.

ABSTRACT: The formation mechanism of calcium carbonate (CC) skeletal tissues in biomineralization has remained poorly understood for a long time. Here, we propose an artificial CC biomineralization system equivalent to the natural one in terms of the primary physicochemical mechanism. Our system is constructed of a polymer gel and a CC solution unsaturated by a dissociated anionic polymer. The gel network consists of proton donor and proton acceptor polymers, which are analogues of polymers in the natural biomineralization system and have affinity for each other through hydrogen bonding interaction. Artificial biomineralization takes place within the polymer gel to produce a monolithic composite of the network and CC, whose powder X-ray diffraction pattern indicates calcite or calcite/vaterite.
