“…The composite's ts2 and tc90 have a tendency to decline, whereas CRI rises as mNS concentration rises. This shortened the vulcanization time by reducing its surface polarity, weakening its propensity to aggregate, enhancing the dispersion of modified nanosilica particles, and further reducing its adsorption of vulcanization accelerators [72][73][74]. Modified nanosilica enhanced the crosslinking density, had a higher degree of contact with the rubber matrix, had a lesser tendency to aggregate, and could be better disseminated in the rubber matrix.…”

The modified nanosilica (mNS), acrylonitrile-butadiene rubber (NBR), and ethylene-propylene-diene monomer (EPDM) nanocomposite was created. The 70/30 EPDM/NBR and 0–10 parts per hundred rubber (phr) of mNS were mixed on a two-roll mill. The impact of mNS on compression set, mole percent uptake (MPU), cure characteristics (scorch and optimal cure time, cure rate index, maximum torque, minimum torque, and torque difference) and mechanical properties (tensile and tear strength, hardness, elongation at break, rebound resilience, and abrasion resistance) of the composites were investigated and discussed. The surface morphology of tensile-fractured EPDM/NBR rubber-mNS was investigated using FESEM. The material's tensile strength, 100% modulus, tear strength, hardness, and abrasion resistance were all improved with an increase in mNS concentration, but rebound resilience and elongation at break were decreased.

“…Nanomaterials and nanoparticles have been acknowledged as a separate research regulation up until this point. In comparison to bulk materials, properties of materials that are divided into considerably smaller sizes, measured in nanometers, alter rapidly and unexpectedly [20][21][22][23][24][25]. Since their discovery, graphene [26] and carbon nanotubes (CNTs) [27] have gained a lot of attention in the elds of physics, chemistry, electrical and electronics engineering and materials science [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”

Nanographene oxide (GO) is used to improve the physical properties of blends of ethylene-propylene-diene monomer (EPDM) rubber/styrene-butadiene rubber (SBR) nano-composites compared with modified nanographene oxide (mGO). The modified Hummers method was used to develop the GO. GO was treated using two types of surface modifiers, 4,4'-diphenylmethane diisocyanate (MDI) and 3-Aminopropyltriethoxysilane coupling agent (KH550), and then incorporated into an EPDM/SBR rubber matrix at different concentrations, processed with an open-mill mixer, and vulcanised. The influence of mGO concentration on EPDM/SBR nanocomposites' swelling and compression set behaviour was investigated in this paper. Comparative analysis was done on the outcomes of various compositions for EPDM/SBR-GO and EPDM/SBR-mGO with nanofiller at 0, 2, 4, 6, 8 and 10 phr. In both GO-filled nanocomposites and mGO-filled nanocomposites, the increase in mGO loading is associated with a significant reduction in mole percent uptake while the compression set increases, according to the current study. In mGO-filled nanocomposites, this phenomenon is more evident than in GO-filled nanocomposites. The effect of the conditioning environment on the characteristics under investigation is clearly distinguished in this study. Swelling resistance and compression set are improved in nanocomposites containing KH550 modified GO.

“…Using the solution mixing technique, a lm is made from the chemicals that are produced after the polymer components are dissolved in an organic solvent. The components are heated before being blended with a mixer in a rubberic for the latex mixing [8][9][10][11]. Rubber is a type of vital material that is frequently used in aerospace, automotive, marine and medicinal applications because of its many distinct characteristics.…”

The main inorganic component of rice husk is silica. Washing the rice husk, followed by combustion and chemical treatment, produced high-surface area amorphous extracted nanosilica (NS) and modified extracted nanosilica (mNS). It was established to reinforce a blend of ethylene-propylene-diene monomer (EPDM) and acrylonitrile-butadiene rubber (NBR) using different amounts of mNS, specifically 2, 4, 6, 8, and 10 phr. The cure properties, mechanical, physical, and swelling resistance examinations of the sulphur-cured nanocomposites were studied. The results showed that while the torques were prolonged with increasing mNS concentration, the optimum cure time (t90) and scorch time (ts2) decreased. The homogeneous distribution of nanosilica particles throughout the rubber matrices was confirmed by the FESEM micrographs. The outcomes guaranteed a discernible improvement in the nanocomposites' examined qualities.
