Polypropylene is one of the most important thermoplastic polymers which has attracted great attention due to its chemical, mechanical and thermal properties. In recent decades, the use of clay nanoparticles, especially montmorillonite in polypropylene matrix, has led to the formation of nanocomposites with unique properties. The problem with these nanocomposites, however, is the low penetration of polypropylene chains into the clay layers and the increased gap between the clay layers. Therefore, in polypropylene nanocomposites, clays are used as adapters for compatibility between nano-clay and polypropylene and to achieve higher levels of montmorillonite diffusion into the polymer matrix. Adapters reduce interfacial tension and increase adhesion between components and ultimately improve mechanical properties. The addition of mineral filler also increases the hardness and reduces the processability and toughness of the nanocomposite which can limit its application. Therefore, resilient materials such as ethylene propylene di monomer are used to correct this defect. In this study, to improve the mechanical properties as well as to increase the functional range of polypropylene, composite nanocomposites containing modified organo-modified montmorillonite (O-MMT) and maleic anhydride-grafted polypropylene (SEBS-g-MA) and rubber Ethylene propylene dna monomer (EPDM) was used. Samples were prepared in two phases by melt mixing by twin screw extruder and then injection molding. In the first phase, the samples were fabricated by combining different percentages of these two adapters in order to homogeneously disperse the nanoclay plates into the polymer matrix and increase the adhesion between the matrix and the nanoclay phase. Tensile and impact tests were used to investigate the mechanical properties. Based on the results of the tensile and impact tests, the sample consisted of PP / O-MMT and a combination of adapters with 5 wt% PP-g-MA and 5 wt% SEBS-g-MA tensile strength of 3.76%, Young's modulus of 3.40% and impact strength increased by 19.88% and elongation to break point decreased by 33.66% compared to pure polypropylene. And was selected as the appropriate sample. In the second phase, EPDM was used to improve the toughness of the nanocomposites with low values of 4.2, 6% by weight, and mechanical tests were performed again. The results of tensile strength increased by 3.42%, Young's modulus by 3.06% and impact strength by 42.54% and elongation at break point decreased by 30.69% over pure polypropylene. In fact, the improvement of impact strength and toughness of the nanocomposite containing 2 wt.% EPDM without decreasing rigidity showed that the positive effect of EPDM resulted in improved mechanical properties. X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) tests were also used to investigate the dispersion of rubber particles and clay nanosheets. The results of XRD test showed that the nanoclay plates distance for the sample containing 5 wt% SEBS-g-MA and 5 wt% PP-g-MA and sample containing 2 wt% EPDM was increased compared to pure nanoparticles and the interlayer state It happened. FESEM images also showed a decrease in particle size and proper distribution of Rubber and O-MMT particles in the polymer matrix for these two samples.
