Influence of APTES Modified HNTs on Properties of NR/EPDM Nanocomposites

Abstract

The use of amino silane (3-aminopropyl) triethoxysilane (APTES) to modify the surface of natural halloysite nanotubes (HNTs) was researched. Natural rubber (NR)/ethylene-propylenediene monomer (EPDM) nanocomposites' cure features, tensile properties, hardness, rebound resilience, and compression set qualities were all examined in relation to the impact of APTES modified halloysite nanotubes (APTES-HNTs). Measurements of swelling and cross-link density, an analysis of abrasion resistance, and examination of fracture morphology under a FESEM were also used to validate the experimental results. Several attributes, including tensile strength, stress at 100% elongation, abrasion resistance, hardness, tear strength, and curing characteristics, were improved by using APTES-HNTs as filler. Compared to base vulcanizates, the produced nanocomposites displayed superior wear characteristics. The increased contact surface area between the filler and rubber matrix led to improvements in mechanical characteristics and swelling resistance. Comparing base vulcanizates and the nanocomposite with 10 phr nanofiller, abrasion loss is reduced by 30%. According to the research, 8 phr of nanofiller might increase tensile strength and tear strength by roughly 112% and 49%, respectively.

Effect of nano-silica surface-capped by bis[3-(triethoxysilyl)propyl] tetrasulfide on the cure behaviors, mechanical properties, swelling resistance and microstructure of styrene-butadiene rubber/acrylonitrile-butadiene rubber nanocomposites

“…This density is intricately connected to the molar mass of the polymer segments existing between crosslinks. The calculation of CLD (υ) involves the utilization of the Flory-Rehner equation [45][46][47]:…”

The effect of nanoclay on mechanical and swelling resistance properties of ternary rubber (NR/SBR/NBR) blends nanocomposites

“…These enhancements encompass heightened tensile strength, increased modulus, and greater resistance to deformation, all of which are indicators of improved material performance. Nevertheless, the realization of these advantages is contingent upon attaining a uniform dispersion of nanoclay throughout the rubber matrix [71][72]. This uniform dispersion is paramount as it allows nanoclay particles to function as e cient crosslinking sites distributed consistently throughout the composite.…”
