功能性碳酸钙材料的仿生合成及表征
Biomimetic synthesis and characterization of functional calcium carbonate materials
摘要
Abstract
Hydrophobic calcium carbonate particles were prepared in situ via the carbonation route by mimicking biomineralization and modified by sodium stearate (NaSt) as a modifier. The modification effect of CaCO_3 was revealed by testing its active ratio, the value of oil absorption, whiteness and the contact angle. The products were characterized through a transmission electron microscope (TEM) and X-ray diffraction (XRD). Then the reaction mechanism was discussed preliminarily. When the dosage of modifier reaches to 2.0 %, the active ratio of CaCO_3 modified by NaSt is 99.9 %. Moreover, the contact angle is 121.62° . Thereby the theory support and synthesis methods will be offered for the preparation of biomimetic materials.关键词
