聚合物与表面活性剂混合模板调控碳酸钙结晶
Crystallization of CaCO3 Induced by Mixed Template of Polymer and Surfactant
摘要
Abstract
Calcium carbonate was prepared by the Na2CO3 with CaCl2 in the mixed templates of polymer (PVA/PSSS) and surfactant (CTAB) at different temperatures and concentrations of CTAB. The products were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD). The results showed that in the PVA/CTAB system the ellipsoid aggregates of calcite could be prepared at 5 ℃ and rosette type and cubic aggregates of calcite and vaterite at 25 ℃ while druses of needle-like aragonite crystals were obtained at 90 ℃. In the PSSS/CTAB system, spherical precipitation of calcite and vaterite could be obtained at 5 ℃, uniform size of spherical vaterite were obtained at 25 ℃. At the temperature of 90 ℃, flower-like aragonite was precipitated. The different complex of polymer and CTAB resulted in the different morphology and crystal form of calcium carbonate关键词
