Abstract

SEM (scanning electron microscopy) and TEM (transmission electron microscopy) investigations of CNT-Ni-Pd composite films prepared by a new three step method are presented. This new method consists of a PVD (Physical Vapor Deposition) process by which films with nanocrystalline Ni were obtained, followed by a CVD (Chemical Vapor Deposition) process in which CNT films with included Ni nanoparticles were obtained, and finally, a PVD process where CNTs were covered with carbonaceous-palladium nanograins. SEM images performed in two modes using a LABE (low-angle backscattered electron) detector and a SE (secondary electrons) detector, show the topography and morphology of the material. TEM and HRTEM is further used to characterize the composition and structure of the CNTs. The density of CNTs in the composite films obtained using different technological parameters was also studied.

Keywords: carbon nanotubes; palladium; PVD; CVD; SEM; TEM
