Abstract
Polyaniline Multi walled Carbon nanotubes (PANI/MWCNTs) nanocomposite thin films have been prepared by non-equilibrium atmospheric pressure plasma jet on glass substrate with different weight percentage of MWCNTs 1, 2, 3, 4%. The diameter of the MWCNTs was in the range of 8-55 nm and length - - 55 55 μm. the nanocomposite thin films were characterized by UV-VIS, XRD, FTIR, and SEM. The optical studies show that the energy band gap of PANI/MWCNTs nanocomposites thin films will be different according to the MWCNTs polyaniline concentration. The XRD pattern indicates that the synthesized PANI/MWCNTs nanocomposite is amorphous. FTIR reveals the presence of MWCNTs nanoparticle embedded into polyaniline. SEM surface images show that the MWCNTs homogenously inside the polyaniline house. It can be concluded that the nanocomposite can be prepared PANI/MWCNTs thin films by plasma jet polymerization and control the optical energy band gap irregulars by controlling the MWCNTs weight concentration.
Highlights
Carbon nanotubes (CNTs), discovered by Iijima and Ichihashi [1], there was great interest in exploring and exploiting their unique characteristics for various applications[2, 3]
It is clear from the table that there is a shift in N–H stretching and C–N stretching bands in the PANI/MWCNTs
The N–H stretch shifts towards high wavenumber. This is an indication that MWCNTs doping causes a change in the structure of the plasma polymerized polyaniline samples
Summary
Carbon nanotubes (CNTs), discovered by Iijima and Ichihashi [1], there was great interest in exploring and exploiting their unique characteristics for various applications[2, 3]. Key words Polyaniline, multiwalled carbon nanotubes, nanocomposites, thin films. It is well known that the strong interaction between the aromatic rings of PANI and the graphitic structures of CNT would be a great benefit to the charge transfer interaction between the two components [16].
