通过过滤稳定的双壁碳纳米管（DWNTs）悬浮液制备了薄、柔韧、坚韧的布基纸，并与单壁碳纳米管（SWNTs）制备的布基纸进行了孔结构和氧化稳定性的比较。在77 K时，DWNTs和SWNTs的N-2吸附等温线分别为11型和IV型，DWNTs的吸附体积是SWNTs的3倍。碳纳米管的氧化起始温度提高。200摄氏度，因为它们的同轴结构。预期的高机械和电气性能与其高表面积和高结构完整性相结合，使DWNTs滤线栅纸成为许多应用的有前途的材料。(c)2005 Elsevier B. V.保留所有权利。
Thin, flexible and tough bucky paper fabricated by filtering a stable suspension of double-walled carbon nanotubes (DWNTs) was characterized from the viewpoint of its pore structure and oxidation stability as compared with that derived from single-walled carbon nanotubes (SWNTs). The N-2, adsorption isotherms of DWNTs and SWNTs at 77 K were of type 11 and type IV, respectively, and also the micropore volume in DWNTs was three times greater than that in SWNTs. The onset temperature of oxidation in DWNTs was enhanced by ca. 200 degrees C due to their coaxial structure. The expected high mechanical and electrical properties when combined with their high surface area and high structural integrity make the DWNTs bucky paper promising materials for numerous applications.
