Polypyrrole/ Functionalized Multi-Walled Carbon Nanotube / Nickel Oxide Nanocomposites: Structural, Morphological, Optical and Composition Analysis Studies

Polypyrrole (PPy), functionalized multi-walled carbon nanotube (f-MWCNT), nickel oxide (NiO) nanocomposites (NCs) films did prepare by PLD technique. The weight percentage of PPy/ f-MWCNT varied from 1 to 5 wt.% whereas NiO fixed with 8wt.%. The nanocomposite films were characteristics by XRD, Raman, FTIR, SEM, and EDS. The XRD pattern shows that the films of (NCs) indicating the amorphous structure of PPy and polycrystalline cubic crystal of NiO and hexagonal phase of f-MWCNT. The dominant phase for (NCs) represented by (002) for f-MWCNT, NCs were shifted to different values of 2θ. Raman spectroscopy the characteristics peaks of (G-D) band at (1280,1320,1570,1610) and the intensity increases with concentration increase to the NCs. FTIR spectra of (NCs) films, refer that C2 has a prominent absorption peak at 1292 cm-1 and C4 at 1550 cm-1 indicated the spectrum of PPy/NiO and from C1 at 2360 cm−1 and C4 at 709 cm−1 indicated the spectrum of PPy/CNT. The morphological studies revealed that tubular surface structure at (C1, C3, and C5) and cluster branching in (C2, C4). It shows agglomeration particles and porosity for the surface of the (NCs) films. For all measurements, the (NCs) succeeded in making the nanoparticles (f-MWCNT/NiO) held together in the polymer (PPy) matrix indicating, that a good interlinkage between PPy, f-MWCNT, and NiO.
