Based on the basic principles of biomineralization, three types of CaCO~3/polymer composites with different contents of polymers can be synthesized through biomimetic synthesis under conditions. In the present work, polyehtylene glycol, polyvinyl alcohol, hydroxyethyl cellulose are used as organic matrices. These synthesized composites, which have special microstructure and morphology and certain orientation, are very similar to the biominerals that are formed in the living organisms through bismineralization. These results are very imp[ortant to the synthesis of the calcium carbonate biomaaterials with excellent properties abnd functions.
