摘要：

以棉布为模板,通过浸渍和低温煅烧,在常压空气气氛中800℃成功地制备出棉纤维形态、纳米氧化镁。X射线衍射、扫描电镜、差热-热重及Fourier红外光谱分析表明:获得纤维状MgO为中空管状结构,煅烧后仍然保有生物模板的原始形状,管径约5μm,管壁厚约1～2μm。由Scherrer公式计算得出晶粒尺寸约14～19nm。

Biomorphic nano-magnesia was successfully derived from cotton fabric templates through infiltration and low temperature calcination methods at 800℃in air.X-ray diffraction,scanning electron microscope,thermogravimetry-differential thermal analysis, and Fourier transform infrared analysis results indicate that the fiber retained the fiber shape of the organic template after calcination, which is a hollow tubular shape.The diameter is 5μm and the thickness of the tube is in the range of 1-2μm.According to the Scherrer formula,the crystal particle size is about 14-19 nm.
