摘　　要：依据生物矿化的基本原理,在动态的条件下,通过仿生合成的方法,以三种高聚物:聚乙二醇、聚乙烯醇、羟乙基纤维素作为有机基质,分别合成了高聚物含量不同的三种CaCO3/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材料的合成具有一定的指导意义.Based on the basic principles of biomineralization, three types of CaCO3/polymer composites with different contents of polymers can be synthesized through biomimetic synthesis under dynamic conditions. In the present work, polyethylene 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 biomineralization. These results are very important to the synthesis of the calcium carbonate biomaterials with excellent properties and functions.
