Maghnite-H+, An Eco-catalyst layered (Algerian Montmorillonite) for Synthesis of Polyaniline/Maghnite Nanocomposites

Abstract

The nanocomposites namely Polyaniline/Maghnite clay (PANI-Mag) composites were synthesized by solution polymerization of aniline in the presence of sulfuric acid and amount of potassium persulfate (PPS), with molar ratio of monomer to oxidant of 2:1, the aniline was polymerized and largely incorporated into the Maghnite,which was confirmed by FTIR ,HNMR spectra and UV-Vis spectroscopy shows some peaks shifts, which indicate the formation of some new bonds and support the intercalation of PANI chains into the interlayer spacing of Maghnite MMT clay. That, the morphology of the PANI-Mag composites changed according to the proportion of clay. The conductive emeraldine salt form of polyaniline PANI-ES is inserted into the layers of maghnite clay to produce the hybrid with high conductivity and solubility in various organic solvents. The resulting organic-inorganic hybrid material, PANI-Mag has been characterized by various physicochemical techniques.

Green Synthesis of Cationic Polyacrylamide Composite Catalyzed by An Ecologically Catalyst Clay Called Maghnite-H+ (Algerian MMT) Under Microwave Irradiation

“…This phenomenon is probably result of the number of ″initiat-ing active sites″ responsible of inducing polymerization, and this number is prorating to the catalyst amount used in reaction. Similar results were obtained by Rahmouni et al [17] and Ferrahi et al [18].…”

Structural Investigation: Anionic Polymerization of Acrylamide under Microwave Irradiation using Maghnite-Na+ Clay (Algerien MMT) as Initiator

“…One adds water distilled to the test-tubes after each siphonage, one agitates during 15 min and one lets the suspension be elutriated before proceeding to new a siphonage. MMT is then recovered by centrifugation with 4500 tr/min during 1 h. With the end, it is washed with distilled water (on several occasions), filtered using one sintered of porosity 3 (maximum diameter of pores from 16 to 40 μm), dried in the drying oven with 105 °C, crushed using a mortar and kept in a desiccators [18,19].…”

Molecular Weight and Solubility Studies of Some Novel Polyaniline Induced by Montmorillonite clay Called Maghnite-H+ (Algerian MMT)

“…Integral ratio of the NH proton signal appeared at 3.55 ppm .Whereas non-reduced form of the product (Emeraldine base) gave a 1 H-NMR spectra with slight shift of the peak positions (i.e. NH protons appear at 4.81 ppm and aromatic protons centered at 7.3 ppm) [19]. …”
