“…This may be due to cure incompatibility effects caused by the decrease in reactive sites on the rubber molecules available for crosslinking reactions [23]. On the other hand, the CRI for NR/EPDM blends increased with GNPs-PEI loadings, which may indicate reduced activation energy for crosslink formation [53] and increased interaction sites for vulcanization [32].…”

The facile approach of non-covalent surface treatment utilizing poly(ethyleneimine) (PEI) polymer was applied to modify graphene nanoplatelets (GNPs). The effects of surface modification and various GNPs-PEI loadings to cure characteristic, mechanical, physical, and morphological properties of natural rubber (NR)/ethylenepropylene-diene-monomer (EPDM) blend nanocomposites were studied and compared to the unfilled NR/EPDM blend and blends filled with unmodified GNPs at similar loadings. We found that the modification of GNPs surface significantly influences the properties of NR/EPDM blends. The addition of GNPs significantly improved the blend's processability, offering approximately a 104.30 % increase in tensile strength obtained with the addition of 5.00 wt% GNPs-PEI. A reduced swelling index of Q f /Q g in parallel with an increase in modified GNPs-PEI content revealed enhancements in terms of rubber-filler interactions between the NR/EPDM matrix and GNPs. These findings were further supported by X-ray diffraction, differential scanning calorimetry, thermogravimetry analysis, and fracture morphology by scanning electron microscope.

“…Therefore, incoporation of nanofillers (polymer or inorganic nanoparticles) at a much lower loading into the rubber latex has been considered to replace the micron-size filler, as the mechanical properties can be remarkably improved due to its very high specific surface area [19,20] .…”

Natural rubber (NR)/styrene butadiene rubber (SBR) nanocomposites have been prepared with nanosized polystyrene (nPS) and polystyrene-encapsulated nanosilica (PS-nSiO 2 ) through latex compounding. The nPS and PS-nSiO 2 were synthesized by differential microemulsion polymerization. 80/20 NR/SBR blend was filled with various loadings of nPS and PS-nSiO 2 (1, 3, 5 and 7 phr). The influence of nanofillers on the tensile properties, dynamic mechanical properties and thermal stability of the resulting nanocomposites was quantified. The results showed the improvement in the tensile strength, modulus and thermal stability by the appropriate amount of nPS and PS-nSiO 2 in the nanocomposites, whilst the elongation at break slightly deteriorated.

“…The maleic anhydride (MAH) modification of different kinds of rubbers is a useful way to give compatibility of immiscible polymer blends as well as to improve interfacial adhesion in polymeric composites [20][21][22][23][24][25]. MAH-grafted EPDM (MAH-g-EPDM) is one of the useful MAH-modified elastomers [26][27][28].…”
