However, because of the difficulties in distributing CNTs homogeneously in metal or ceramic matrix by means of traditional composite processes, it has been doubted whether CNTs can really reinforce metals or ceramics. In this study, CNT reinforced metal and ceramic nanocomposites with homogeneously distributed CNTs with strong interfacial strength are fabricated by a novel fabrication process, i.e. molecular level process. For the structural applications of CNT nanocomposites, CNT/Cu nanocomposite could be fabricated with excellent strength, increased by 3 times compared to Cu matrix, and high elastic modulus, increases by 1.6 times compared to those of Cu. In case of CNT/Alumina nanocomposite, hardness increased by 1.4 times and fracture toughness increased by 1.3 times compared to those of alumina. It indicates that the CNTs could be the most effective reinforcements for metal or ceramic matrices. For the functional application of CNT nanocomposites, the CNT/Co nanocomposite can be applied to high-efficiency field emitter for applications as back light unit or field emission display. | | ISBN: | 978-1-4200-8503-7 |
