【摘要】通过仿生合成的方法,以羧甲基淀粉、醚化淀粉、磷酸酯淀粉作为有机基质,在制备CaCO3晶体的过程中,通过傅里叶变换红外光谱对3种变性淀粉进行了跟踪测试表征。结果表明:3种变性淀粉分子中的C—O谱峰的强度均发生了变化,随着反应时间的增加,C—O峰强度不断减小,且减小的幅度非常大。对3种变性淀粉与CaCO3的作用机理进行了初步探讨。更多还原

【Abstract】 Three types of CaCO₃ can be synthesized through biomimetic synthesis. In the present work, （carboxymethyl）-starch, （etherified）-starch, and phosphate-starch, used as organic matrices, were studied by FTIR. The result shows that the intensity of C—O peaks of the three modified-starchs changed. In addition, the intensity of C—O peaks was weakened or vanished obviously with the increase in time. The action mechanism of the modified-starchs and CaCO₃ was briefly discussed.更多还原
