摘　　要：以炭黑为原料,在温和条件下的无水乙醇相中,培养出从根本上不同于炭黑粒子聚集体结构的微米尺寸的带状结构碳(质)新型材料。采用扫描电子显微镜(SEM)、高分辨透射电子显微镜(HRTEM)、电子衍射对新材料结构进行了表征。研究结果表明:在温和条件下的有机溶剂中以炭黑为原料制备出形态与结构完全不同于炭黑的带状晶体结构新型碳(质)材料,统计结果显示碳(质)微带的厚度约为1～5μm,宽度约为5～30μm,长度可达数毫米。A micro-ribbon structure of carbon (carbonaceous)materials grown from carbon black in liquid phase under very mild conditions, even at room temperature, was reported. The structure was characterized with scanning electron microscopy, high resolution transmission electron microscopy, and electron diffraction pattern. The results show that the microribbons could be prepared from carbon blacks in organic solvent under mild environments, and the microribbons are crystal structures and from 1 to 5 μm in thickness and from 5 to 30 μm in width and up to several millimeters in length from statistics.
