采用缓慢气相扩散法在N-[（2-羟基）丙基-3-三甲基铵]壳聚糖氯化物（HTCC）溶液中制备了棒状、梭形、梭形和梭形CaCO 3颗粒。采用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、粉末X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）和热重分析（TGA）等方法对CaCO 3颗粒进行了表征。研究了不同HTCC浓度、Ca 2+和Mg 2+浓度、温度和陈化时间对CaCO 3颗粒性能的影响。结果表明，HTCC与Ca 2+之间的静电相互作用、HTCC分子间和分子内的相互作用对不同形貌和晶型CaCO 3的结晶起着关键作用。通过对不同老化时间下所得碳酸钙颗粒的分析，提出了高温CC对碳酸钙结晶的调控机理。
Disk-like, rod-like, spindle and bundle-like CaCO3particles were modulated inN-[(2-hydroxyl)-propyl-3-trimethylammonium] chitosan chloride (HTCC) solutions using a slow vapor diffusion method. The CaCO3particles were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and thermogravimetry analysis (TGA) methods. The influences of various concentrations of HTCC, Ca2 +and Mg2 +, temperature and aging time, on the properties of CaCO3particles were investigated. It was found that the electrostatic interaction between HTCC and Ca2 +, the intramolecular and intermolecular interactions between HTCC molecules played a key role in the crystallization of CaCO3with different morphologies and polymorphs. Based on the analysis of CaCO3particles obtained under different aging time, a mechanism of HTCC modulating CaCO3crystallization was proposed.
