Controllable Fabrication of Calcium Carbonate Hollow Microspheres with Micro-nano Hierarchical Structure
摘要
Abstract
With polyvinyl pyrrolidone (PVP) and sodium dodecyl sulfonate (SDSN) as the template, calcium car-bonate hollow microspheres with micro-nano hierarchical structure were successfully synthesized using sodium carbonate and calcium chloride as starting materials through a precipitation reaction method at reaction temperature of 50℃. The products were characterized by scanning electronic microscopy (SEM), transmission electron micro-scope (TEM), X-ray diffraction (XRD) and other detection methods. The results show that the hollow calcium car-bonate microspheres with micro-nano hierarchical structure are about 4-6μm in diameter. The shell thickness of calcium carbonate hollow microspheres is about 200 nm, which consists of calcium carbonate particles with size about 60 nm. The phase of calcium carbonate hollow microspheres is composed of calcite and vaterite. Excellent dispersibility and spherical morphology of calcium carbonate hollow microspheres can be achieved with addition of 0.1 mol/L SDSN and 0.4 g PVP consequently.关键词
