摘要：
Composites of beta-chitin with calcium carbonate polymorphs were prepared by precipitation of the mineral into a chitin scaffold by means of a double diffusion system. The beta-chitin was obtained from the pen of the Loligo sp. squid. The three main polymorphs of calcium carbonate: aragonite, calcite and vaterite, were observed. Their location within the matrix is a function of the polymorph. The supersaturation inside the compartmentalized space in the chitin governs the location and polymorphism of the crystals.
