| dc.description.abstract | Nanocomposites from Styrene-Limonene copolymers and Algerian organophilic-clay named Maghnite-CTA+ (Mag-CTA+), were prepared by in-situ polymerization using different amounts (2, 5, and 10% by weight) of clay and Azobisisobutyronitrile (AIBN) as a catalyst. The Mag-CTA+ is an organophilic silicate clay prepared through a direct exchange process, using Cetyltrimethylammonuim bromide (CTAB) in which it used as green nano-filler. The preparation method of nanocomposites was studied in order to determine and improve structural, morphological and thermal properties of Sty-Lim copolymer. The struc ture and morphology of the obtained nanocomposites (Sty-Lim/Mag) were determined using Fourier trans form infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electronic microscopy (SEM) and transmission electronic microscopy (TEM). The analyses confirmed the chemical modification of clay layers and the intercalation of Sty-Lim copolymer within the organophilic clay sheets. Exfoliated structure was obtained for the lower amount of clay (2 wt %), while intercalated structures were detected for higher amounts of clay (5 and 10 wt %). The thermal properties of the obtained nanocomposites were studied by thermogravimetric analysis (TGA) and show a significant improvement in the thermal stability compared with the pure copolymer. The obtained nanocomposites show an optimal degradation temperature of 320°C. | pt_PT |
