摘要 以定量滤纸为生物模板成功制备了具有滤纸形貌的微纳米Na2SO4晶体,经过吸水和低温的结晶过程合成了相变材料Na2SO4.10H2O。并借助扫描电子显微镜(SEM)、X-射线粉末衍射仪(XRD)和差示扫描量热仪(DSC)对产物进行了表征。结果表明,产物纯度很高,且很好地遗传了模板的形貌。同时,最终合成的相变材料Na2SO4.10H2O表现出了良好的储能效果,相变潜热大于200J/g。 The biomorphic Na2 SO4 crystal were prepared using filter paper as bio-templates, and transformed it into Na2SO4 · 10H2O during the process both drinking and crystallization under low temperature. Finally, SEM, XRD and DSC were used to characterize the morphology, crystalline phase and thermal property of the products. The results showed that products had high purity and mimicked well morphologies of the fiher paper. At the same time, the resulted phase change materials of Na2SO4 · 10H2O showed good heat storage property and their phase change latent heat exceeded 200J/g.
