Synthesis and temperature dependent electrical conductivity study of hybrid multiwall carbon nanotubes with metal nanoparticles

We report the electrical studies of nanocomposites of Multiwalled Carbon Nanotubes (MWCNTs), Ag CNT and Ni CNT.The MWCNTs were synthesized by chemical vapour deposition (CVD) method. Solvent evaporation method is used to prepare Ag CNT/ Ni CNT composite films. Scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD) were used to study structure and morphology of the composites. The temperature dependant conductivity measurements and I-V Characteristics for thenanocomposites were taken using fourprobe method.
