Metal-CNT, Composite, Electrical Property, Raman Spectroscopy, Thickness


The composite of Metal – MWCNT (Metal: Cu) were made by using solid-state reaction method for 1 hour at R.T. after mixing the Multiwalled - CNT (MWCNT) and Copper (Cu) powder with 3% weight of Cu. The result of electrical property measured using LCR meter indicated that the conductivities value of MWCNT/Cu was increased in proportion to the increase of layer thickness of composite and the increasing of frequency measurement. On the other hand, the capacitance value of the MWCNT/Cu composite sample was decreased by the increasing of frequency measurement. From the analysis of cole-cole plot, the MWCNT/Cu composite indicated the peak maximum at certainl frequency, which shows the possibility of achievable polarizability. We have measured the Raman spectra of MWCNT/Cu composites to evaluate the state of dispersion and the Cu-filler interactions reflected, by shifts changes of the peaks. All the Raman bands of the carbon nanotubes are seen at wave number around of 1326 cm-1 (D band), and a wave number around of 1617 cm-1 (second harmonic G band).
