| 摘 要： | 以超长定向碳纳米管(ACNTs)阵列为骨架，中温煤焦油沥青为浸渍剂，采用浸渍-炭化工艺经过一个循环制备了密度约为1.25 g·cm-3的沥青基定向碳纳米管/炭(ACNT/C)纳米复合材料。采用扫描电子显微镜(SEM)、偏光金相显微镜(PLM)、X射线衍射(XRD)和Raman光谱分析对这种新型纳米炭材料进行了表征。结果表明ACNT/C中沥青炭为明显的各向异性组织，以碳纳米管为核心形成了非常细密的流线型层片结构，具有较高的晶化程度。采用热失重分析(TGA)方法考察了材料在空气中的热稳定性能，发现ACNT/C纳米复合材料在空气中的热失重初始温度比相同工艺条件下，以炭纤维为骨架制备的密度相近的炭/炭(C/C)复合材料提高了50 ℃左右。
