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。 Using cotton cloth as a template, cotton fiber morphology and nanometer magnesia were successfully prepared by impregnation and calcination at 800 ℃ under atmospheric air. X-ray diffraction, scanning electron microscopy, DTA-TG and FTIR spectroscopy showed that the fibrous MgO was obtained as a hollow tubular structure with the original shape of biological template remaining after calcination. The diameter of the template was about 5 μm and the wall thickness of the tube was about 1 ~ 2 μm . Calculated by the Scherrer formula, the grain size is about 14 ~ 19nm.
