Influence of the clay modification and compatibilizer on the structure and mechanical properties of ethylene–propylene–diene rubber/montmorillonite composites

Abstract: Ethylene-propylene-diene rubber (EPDM)/ montmorillonite (MMT) composites were prepared through a melt process, and three kinds of surfactants with different ammonium cations were used to modify MMT and affect the morphology of the composites. The morphology of the composites depended on the alkyl ammonium salt length, that is, the hydrophobicity of the organic surfactants. Organophilic montmorillonite (OMMT), modified by octadecyltrimethyl ammonium salt and distearyldimethyl ammonium salt, was intercalated and… Show more

“…When PA6/PP matrix, OMMT, and PP-g-MA were mixed together, PP-g-MA could easily penetrate the interlayer of organoclay. The driving force for intercalation originates from the strong hydrogen bonding between maleic anhydride groups in PP-g-MA and amine groups in organoclay and leads to the expansion of interlayer spacing and a further weakening of interactions between the silicate layers [12]. This facilitates the intercalation of PA6 chains into silicate galleries and resulted in the formation of the exfoliated structure as confirmed by XRD results earlier.…”

“…Below 100°C, MMT exhibits a relatively higher weight loss than OMMT corresponding to the removal of water from interlayer coordinated to Na + . At this temperature, the weight loss for OMMT is lower because of the organophilic properties of OMMT containing alkyl ammonium ions [12]. The weight loss observed at 100-600°C for MMT may be attributed to the decomposition of hydrogen-bonded water molecules and some of the OH group from tetrahedral sheets [16].…”

“…For nonpolar saturated EPDM matrix, the functional oligomers, with polar telechelic groups as a compatibilizer, e.g., EPDM grafted by maleic anhydride [9][10][11] or glycidyl methacrylate, 12 were used to improve the interfacial interaction. In addition, there are hydroxyl groups 13,14 on the surface of clay layer, carboxylic acids have been used to intercalate into clay gallery to modify the clay.…”

“…After our success, a lot of researchers have started to study in these field and a huge number of research articles have been published. [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] We expect that clay-based nanocomposite technology is grown into the universal method for high-performance materials from structural to functional ones extensively.…”
