摘要
在Klett等人于2000年制备的韧带网络型碳泡沫和Bruneten等人在2002年制备了一种空心微球碳泡沫材料结构的基础上,分别经过微观结构优化、碳化、石墨化处理,制备出了一种空心微球/网络复合型碳泡沫材料.扫描电镜和体视显微镜测试结果显示网络韧带和球形空腔呈现明显的空间周期性.X射线衍射(X-ray diffraction,XRD)图谱中,26°处的衍射峰表明该试样具有较高的石墨化特征.同时,对该材料的形成机理进行了分析.
On the basis of the ligamental reticulated carbon foam by Klett in 2000 and hollow microsphere carbon foam by Bruneton in 2002,a hollow microsphere/ reticulated composite carbon foam is prepared by microstructural optimization,carbonization and graphitization sequentially.The scanning electron microscope （SEM ） and stereo microsccope tests demonstrate that both reticulated ligament and globe cavity show obvious spacial periodicities.Diffraction peak of X-ray diffraction （XRD ） at 26° indicates that the sample features graphitization.Besides,the forming mechanism is also analyzed.
