The influence of HNTs on the mechanical properties, swelling resistance, and microstructural properties of nanocomposites based on silicone rubber

Article scientifique 2023 Anglais

Résumé

Abstract Halloysite nanotubes (HNTs), an innovative material, were integrated into a silicone rubber (SR) matrix. This investigation aimed to assess the influence of varying HNTs concentrations on the curing behavior, mechanical properties, swelling resistance, and microstructural features of SR/HNTs nanocomposites. These nanocomposites were formulated by incorporating HNTs at different concentrations (0-10 phr) through a two-roll mill. The cure characteristics revealed an upsurge in maximum torque (MH) with escalating HNTs loading, accompanied by a decrease in cure time (t90) and scorch time (ts2). The abrasion resistance exhibited an increment with increasing HNTs loading, reaching optimal levels at 6 phr, and tensile characteristics demonstrated improvement up to this optimal loading. Morphological analysis illustrated the uniform dispersion of HNTs within the SR matrix, indicating a positive interaction between HNTs and silicone rubber.
