Abstract
In an in-situ surface modification method, nano-silica (NS) was treated with bis[3-(triethoxysilyl)propyl]tetrasulfide (Si69, often referred to as TESPT), a commercially available SCA (silane coupling agent). This produced surface-functionalized NS, also known as modified nanosilica (mNS). The influence of using this mNS as a filler in acrylonitrile-butadiene rubber/styrene-butadiene rubber (SBR/NBR) composites was examined in this study. The results show that the silanol groups in TESPT form chemical connections with the surface of the NS, which significantly increases the rubber-matrix nanocomposite's curing efficiency and improves its mechanical properties. The reason for this enhancement is the in-situ surface modification of the NS by the SCA, which significantly raises the filler's miscibility and compatibility with the rubber matrix.
