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

Abstract

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. Keywords: PPy/f-MWCNT/NiO nanocomposites, pulsed laser deposition, Nd:YAG Laser.

Facile fabrication of polypyrrole/NiOx core‐shell nanocomposites for hydrogen production from wastewater

“…The out‐of‐plane bending vibrations of CH provide the characteristic peak at 872 cm −1 . The presence of two additional peaks in the PPy ring at 780 and 672 cm −1 that result from the C‐H out‐of‐plane ring deformational vibration confirms that pyrrole has been polymerized or oxidized 34 . Finally, a tiny peak that characterizes the NH and CH stretching is also seen at ~3004 cm −1 .…”

Influence of Incorporating MWCNTs on Some Physical Characteristics of Blend Nanocomposites

“…It should be mentioned that the MWCNTs peaks are, to some extent, similar to that of graphite, possibly due to the comparable intrinsic graphene structure featured. CNTs, which are composed of multilayer structures, exhibit similar XRD graphite samples are especially planar (002) [39].…”
