依据生物矿化的基本原理，在动态条件下，通过仿生合成的方法，以三种高聚物：聚乙三醇、聚乙烯醇、羟乙基纤维作为有机基质，分别合成了高聚物含量不同的三种CaCO~3/高聚物复合材料，这些无机/有机复合材料与生物体内经过生物矿化作用所形成的生物矿物颇为相似，具有独特的微观结构形态和一定的取向，这些结果对于具有生物相容性和优异性能的碳酸钙功能的合成具有一守的指导意义。

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.

Key words: CALCIUM CARBONATE, POLYGLYCOL, POLYVINYL ALCOHOL, COMPOSITE WOOD
