摘    要:生物矿化是一种广泛而复杂的固液之间、有机物和无机物间的物理化学过程.以少量有机质为模板,进行分子操作,高度有序地组合成无机材料.有机基质能作为构造支持的惰性底质或矿物沉淀的局限空间和核化作用的表面,确定矿物质点的形态大小、空间排列、结晶取向和同质多晶类型,并与生物晶体一起确定生物矿物硬体的机械性质.

关 键 词:生物矿化  纳米碳酸钙  原位合成  有机基质  空间网络结构

Abstract:A new method for mimic biomineralization was used to synthesize CaCO3 . The organized organic substrates, which could associate with Ca 2+ by means of molecular recognition and induce the nucleation and growth of CaCO3, were synthesized fristly, and followed by the preparation of the CaCO3 by carbonation of a solution of Ca(OH)2 with CO2. Well dispersed spindle-like nano-CaCO3 particles with an average width of 50 nm and a ratio of diameter to length about 1:5 were obtained under the given experimental conditions. The products were characterized by FTIR spectra, TGA analysis and transmission electron microscope(TEM).
Keywords:Biomineralization  CaCO  3 nanoparticle  Synthesis in situ  Organic substrates  Spacial framework
