Abstract

Novel carbon composites are fabricated through catalyzed CVD growth of carbon nanotubes directly on the inner surfaces of monolithic carbon aerogel (CA) substrates. Uniform CNT yield is obtained throughout the internal pore volume of CA monoliths with macroscopic dimensions. These composites possess large surface areas (>1000 m(2) g(-1)) and exhibit enhanced electrical conductivity following CNT growth.

摘要

通过在整体式碳气凝胶 (CA) 基底的内表面上直接催化 CVD 生长碳纳米管，制备了新型碳复合材料。在具有宏观尺寸的 CA 整体的整个内部孔体积中获得了均匀的 CNT 产率。这些复合材料具有大的表面积 (>1000 m(2) g(-1))，并且在 CNT 生长后表现出增强的导电性。
