在单片碳气凝胶（CA）衬底的内表面直接催化CVD生长碳纳米管，制备了新型碳复合材料。碳纳米管产率在具有宏观尺寸的CA单体的整个内部孔体积中都是均匀的。这些复合材料具有较大的表面积(> 1000 m(2) g(-1))，并且在碳纳米管生长后表现出增强的导电性。
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.
