Abstract
In the last years, serval researches have been focused on organophilic clay as reinforcements for polymer matrices. In this respect, the aim of this chapter is to valorize mineral resources; montmorillonite clay was modified using hexadecyltrimethylammonium bromide (CTAB) and then used as reinforcement in a thermoplastic copolymer matrix to compare with pristine montmorillonite and commercially organo-modified montmorillonite (Cloisite 20A). The nano-composites were prepared by melt compounding using a blend of polyamide 6 (PA6) with acrylonitrile butadiene styrene (ABS) as the matrix. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), X-ray diffraction (XRD) as well as mechanical and rheological tests were carried out to understand the properties of these nano-composites at different particle contents. The results obtained clearly showed that the Moroccan montmorillonite was successfully modified and its addition in the selected matrix substantially improved the properties of the resulting nano-composites.
