Polylimonene-clay nanocomposites (PLM-Mag 2, 3, 6 and 10% by weight of clay) were prepared by mixing Maghnite-CTA+ (Mag-CTA+) and polylimonene (PLM) in solution using ultrasonic irradiation. The catalyst preparation method were studied in order to determine and evaluate their structural, morphological and thermal properties. The Mag-CTA+ is an organophylic montmorillonite silicate clay prepared through a direct exchange process, using green natural clay of Maghnia (west of Algeria) called Maghnite. The Algerian clay was modified by ultrasonic-assisted method using cetyltrimethylammonuim bromide (CTAB) in which they used as green nano-reinforcing filler. Polylimonene was obtained by the polymerization of limonene, using Mag-H+ as a catalyst. The morphology of the obtained nanocomposites was studied by X-ray diffraction (XRD), scanning electronic microscopy (SEM), transmission electronic microscopy (TEM) and infrared spectroscopy (FT-IR). Thermogravimetric analysis (TGA) shows that the nanocomposites have a high degradation temperature (200−250 °C) compared with the pure polylimonene (140 °C). The analyses confirmed the chemical modification of montmorillonite layers and their uniformly dispersion in the polylimonene matrix. Exfoliated structures were obtained for low amounts of clay (2 and 3% by weight), while intercalated structures and immiscible regions were detected for high amounts of clay (6 and 10% by weight).

“…This behavior leads to a large dispersion of the clay sheets in the PLM matrix. It can be noted that the use of ultrasound for the synthesis of nanocomposites has a great advantage compared with classic methods which is take 24 h of reaction time [30].…”

“…The use of organoclay (Mag-CTA + ) has an impact on the morphology of the prepared nanocomposites, especially in the dispersion of in-situ polymerization methods. For these reasons, several nanocomposites based on polymers and organoclay were prepared [ 20 , 21 , 22 , 23 , 24 ]. By reviewing the literature, we found that no previously published work has described the use of natural clay as a nano-reinforcing filler in the preparation of green-nanocomposites based on rosin-limonene copolymer.…”

Green nanocomposites from rosin-limonene (Ros-Lim) copolymers based on Algerian organophilic-clay named Maghnite-CTA+ (Mag-CTA+) were prepared by in-situ polymerization using different amounts (1, 5 and 10% by weight) of Mag-CTA+ and azobisisobutyronitrile as a catalyst. The Mag-CTA+ is an organophilic montmorillonite silicate clay prepared through a direct exchange process; the clay was modified by ultrasonic-assisted method using cetyltrimethylammonuim bromide in which it used as green nano-filler.The preparation method of nanocomposites was studied in order to determine and improve structural, morphological, mechanical and thermal properties ofsin.The structure and morphology of the obtained nanocomposites(Ros-Lim/Mag-CTA+) were determined using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electronic microscopy and transmission electronic microscopy. The analyses confirmed the chemical modification of clay layers and the intercalation of rosin-limonene copolymer within the organophilic-clay sheets. An exfoliated structure was obtained for the lower amount of clay (1% wt of Mag-CTA+), while intercalated structures were detected for high amounts of clay (5 and 10% wt of Mag-CTA+). The thermal properties of the nanocomposites were studied by thermogravimetric analysis (TGA) and show a significant improvement inthe thermal stability of the obtained nanocomposites compared to the purerosin-limonene copolymer (a degradation temperature up to 280 °C).

“…To meet industry standards while respecting the environment, acids have been replaced by another clay-based ecocatalyst called Maghnite. The latter is of the montmorillonite type and has been the subject of several studies [14][15][16]. The clay layer has a hydrophilic character and metamorphoses into organoclay (surfactant) to facilitate the wetting of the polymer molecule on the clay surface [17,18].…”

This work focuses mainly on the preparation and characterization of polypyrrole/organically modified clay nanocomposites. Organoclay/polypyrrole nanocomposites were prepared by oxidative polymerization of pyrrole in aqueous medium using ferric chloride as the oxidant. Initially, cetyltrimethyl-ammonium bromide and tetrabutyl-ammonium hydrogen sulphate were used as organophilic to modify clay and form an organic clay. After that, polypyrrole/organically modified clay nanocomposites were synthesized by in situ polymerization process in which pyrrole was polymerized in the presence of different proportions of organic clay. The effects of the nature of the organic clays and the preparation method were studied in order to evaluate their structural, morphological and thermal properties. X-ray diffraction (SAXS), Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, transmission electron microscopy, were used to define the characteristics of the materials obtained. The obtained results confirm the intercalation of molecules of salt in the clay layers, and good interaction with the polymer. Thermogravimetric analysis showed better thermal stability of nanocomposites compared to pure polypyrrole. The conductivity behaviour of nanocomposites was also examined.
