“…However, the incorporation of FG particles leads to shift of some bands of PANi. Two characteristic peaks of PANi are present in composite at 3438 cm −1 and 1167 cm −1 and are representative of N-H stretch and an electronic-like band [ 3 , 4 , 21 , 22 ]. The band appearing at 1538 and 1629 cm −1 corresponds to benzenoid and quinoid vibrations in PANi, respectively.…”

“…These limitations can be overcome by the preparation of CP blends and composites possessing electrical properties of conducting polymer and mechanical exploits of host matrix [ 19 ]. The use of a compatibilizer including copolymer is another method to improve the compatibility in polymer blends [ 20 , 21 , 22 , 23 ]. The mechanical behavior of polymer nanocomposites can also be affected largely by the presence of graphite particles.…”

Graphite has recently gained scientific and industrial attention due to its high electrical conductivity. In the current endeavor, a new way to fabricate novel and multifunctional nanocomposites using functional graphite (FG) as filler is presented. The fabrication of multilayered conducting composites of PANi/PMMA/PPG-b-PEG-b-PPG was carried out via in situ polymerization, using polyaniline (PANi), poly(methyl methacrylate) (PMMA) and block copolymer as matrices in the presence of FGfiller. The growth of PANi chains is manifested by PMMA due to the formation of H-bonding between imine and carbonyl groups of PANi and MMA units, respectively, and are responsible for ion exchange sites. FTIR spectroscopy was used for structural elucidation of composites while elemental analysis was accomplished by XPS and EDX spectroscopy. The morphology of the prepared PANi/PMMA/PPG-b-PEG-b-PPG@FG composites was inspected by the SEM. The structure and crystallinity of the composites was investigated via XRD. The improved thermal stability and properties of the nanocomposites were observed using TGA and DSC. The conductivity measurements were used to characterize the electrical conductivity performance of the resulting composites. The presence of functional filler as well as polyaniline shows a significant contribution towards the enhancement of electrical conductivity of PANi/PMMA/PPG-b-PEG-b-PPG@FG nanocomposites.

“…The main characteristic band at 791 cm -1 is ascribed to the aromatic N-H stretching vibration of the secondary aromatic amine bending vibration [43]. Furthermore, the two main band at 876 cm -1 and 1121 cm -1 are ascribed to the out-of-plane bending vibration of C-H within the 1,4-disubstituted aromatic ring and the stretching vibration of C-N of the secondary aromatic amine structures bending vibration, respectively [44]. Raman spectra of the PANI is shown in…”

In this article, a novel silicon-based electrode was designed with the facile solution methods. With the modification of highly conductive PEDOT:PSS layer on the SiNWs by the spin-coated method (SiNWs-PSS), three-dimensional (3D) porous network polyaniline nanofibers (PANI) film was uniformly electrodeposited on the silicon surface (SiNWs-PSS@PANI). The sheet resistances of the PEDOT:PSS layer with different surfactants as well as the deposition time of the PANI were investigated. After optimization, the fabricated SiNWs-PSS@PANI electrode displayed high capacitance about 301.71 mF cm -2 at the current density of 1mA cm -2 , which enhanced~29 fold comparing to 10.18 mF cm -2 of electrode without the PEDOT:PSS layer between the SiNWs and PANI (SiNWs@PANI), outperforming most values of the reported silicon-based electrodes. The electrode designed in this paper provides a new idea to fabricate high-performance of silicon-based micro-supercapacitors with the simple and low-temperature method.
