以宏源精选煤为原料在微波等离子体条件下制备出一种新颖结构的碳材料,运用场发射扫描电子显微镜、透射电子显微镜和能量色散谱技术对产物进行表征.结果表明:产物形状似莴笋状,外层石墨化程度较好,其最大宽度约为170 nm,长度则为4~5 μm,且呈定向排列.这种新颖结构的纳米碳材料有望在场发射、增强材料等方面显示出巨大的应用潜力.
Aligned carbon film with novel structure was synthesized from Hongyuan washed coal by microwave plasma. Field-emission scanning electron microscopy (FE-SEM), high resolution transmission electron microscopy (HRTEM) and energy dispersive X-ray spectroscopy (EDS) were used to characterize the microstructure of the products. The results indicated that the products were formed in the shape of aligned bamboo shoots, their out-layers possessed a higher degree of graphitization, the maximum width was about 170 nm and the length was 4-5μm. The novel aligned carbon film is expected to have a great applied potential of field emission and intensifier of composite materials.
