Dataset for synthesis of conducting polymers nanocomposites based on aniline and 4-amino-benzylamine catalyzed by chromium (III) exchanged maghnite (Algerian MMT) via in situ polymerization

Abstract

In this data we report on conductors polymers nanocomposites synthesized by in situ polymerization of aniline (ANI) and/or 4-aminobenzylamine (4-ABA) in presence of chromium montmorillonite (MMT-Cr⁺³) and ammonium persulfate as oxidizing agent. Homopolymers and copolymers (PANI-co-4-ABA) were prepared at various initial monomer composition and were characterized by Fourier transform Infrared (FT-IR) and UV–vis spectroscopy, X-ray diffraction (XRD) and cyclic voltammeter. The data describes the behavior of the corresponding homopolymers Poly (4-ABA) and (PANI) and showed that the in-situ polymerization produced real nanocomposites containing aniline and 4-aminobenzylamine units and films of products exhibit good electrochemical properties.

2. Experimental design, materials, and methods

2.1. Preparation of Maghnite-Cr⁺³ (MMT-Cr⁺³)

The raw-clay sample (Raw-MMT) was washed with distilled water to remove impurity [3,4]. The obtained montmorillonite (10 g) was crushed for 20 min using a Prolabo ceramic balls grinder. The greatest proton saturation of the <2 mm fractions of clay were obtained by first saturating with Na + ions using 1 M NaCl solution and to confirm the absence of chloride we use the silver nitrate [5,6]. To obtain MMT-Na+ with chromium intercalated (MMT-Cr⁺³), the MMT-Na+ was dispersed into a 1 M CrNO₃ solution and stirred for 24 h and then the solid was recovered by centrifugation and washed with abundant water [7,8]. The catalyst composition was determined by X-ray fluorescence, the obtaining data are listed in Table 1 [9,10].

2.2. Synthesis of polymers/Maghnite-Cr⁺³

Polymer/MMT-Cr⁺³ nanocomposites have been prepared by In-Situ process and the synthesis procedure is briefly described as follows:

The monomers were added by various feed mole fractions. In all cases, the mole ratio of oxidant to the total monomer was defined.
