摘要：

Silicon carbide (SiC) cellular ceramic skeletons based on ceramic pillars of similar to 250 mu m in diameter and porous micro-channels of similar to 700 mu m Were used as support to grow long and aligned crystalline carboxyl functionalized carbon nanotubes (COx) by floating catalyst chemical vapor deposition. The resulting hybrid COx/SiC material retained water and allowed the flow of oils and gasoline through the specimen, showing, thus, superhydrophobic and superoleophilic properties. In addition, the developed hybrid material exhibited high electrical conductivity with a good ohmic contact at the COx-SiC interface. (C) 2014 Elsevier Ltd. All rights reserved.
