“…These bands appeared also in the spectrum of the precursor (figure not shown). On the other hand, the bands at 408 nm suggest the existence of quinoid imine units (-C=N-) [39][40][41]. From this spectroscopic analysis, it can be concluded that the synthesized PoPD with modified-clay (Mag-Cu and Mag-Co) has a head-to-tail type arrangement with the benzenoid and quinoid structures in the phenazine-like backbone [40][41][42].…”

This work describes the synthesis and characterization of new poly(o-phenylenediamine (PoPD)/modified-clay nanocomposite materials. For the synthesis, the raw clay (named as Mag) used in this study was from Maghnia (west Algeria), (Mag) clay was ion-exchanged with cobalt(II) sulfate hydrate and copper sulfate. The modified-clays were then dispersed in a oPD monomer-containing acidic solution to carry out in-situ intercalative oxidative polymerization by ammonium persulfate. XRF and XRD characterization reveal the success of ion-exchange to form highly intercalated Mag-Co and Mag-Cu clays. After polymerization, the disappearance of the interlayer-spacing diffraction peak for the PoPD-Mag-Cu and PoPD-Mag-Co nanocomposites points out fully exfoliation of the clay structure. The formation of intercalated PoPD into modified-clay nanocomposites was confirmed by XRD, TEM, TG analysis, FTIR spectroscopy and UV-vis studies. The nanocomposites show optical properties and the redox processes observed by cyclic voltammetry indicate that the reported polymerization into modified-clays leads to electroactive hybrid materials. All these properties make these polymer/clay nanocomposites attractive materials for multiple applications.

Hybrid materials based on Al2O3, modified with polyaniline have been obtained. Samples have been synthesized by chemical polymerization of aniline monomer with Al2O3 nanoparticles, the ammonium persulfate have been used as oxidizers. The resulting samples were fully characterized by X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR), scanning electron microscopy (SEM), and UV‐vis spectroscopies, which have shown that polymerizations have been carried out. Importantly, this work represents an efficacious way of setting the optical properties of the synthesized nanocomposites, obtained by adjusted the amounts of Al2O3 during polymerization, the analysis shows that the lowest evaluate of optical band gap is 2.88 eV for PANI@Al2O3 (4%) compared to PANI@Al2O3 (2%), and PANI@Al2O3 (6%) with 2.95 and 2.91 eV, respectively. Good electroactivity response where achieve two pairs oxidation/reduction with improved thermal stability for the synthesized hybrid materials have been observed.

The preparation of hybrid materials, namely poly(p-anisidine)@Clay (poly (pAnis)@Clay) and poly(p-anisidine)@cetyltrimethylammoniumbromide-Clay (poly(pAnis)@CTAB-Clay), prepared by oxidative polymerization process is presented. The formation of nanomaterials has been confirmed by XRF, XPS, FT-IR, and UV-Vis spectroscopy. Interestingly, the study of the optical band gap energy (E g) evince lowest value of 3.22 eV for poly(pAnis)@CTAB-Clay compared to poly(pAnis)@Clay with 3.26 eV. XRD results demonstrate that the intercalation of the poly(pAnis) into the Clay was confirmed by the increased interlayer spacing, the exfoliation and intercalation forms were affirmed in the TEM images. In addition, the electrochemical behavior indicates that the prepared nanocomposites are electroactive. These results are heartening in respect with the objective to utilize them in the field of technology and research related to the photovoltaics application.
