Abstract

Incorporating zinc oxide nanoparticles (ZnONPs) into nylon significantly alters its mechanical and thermal characteristics. Nanocomposites with 0, 1, and 2 wt% ZnONPs were created through a two-step process of dry mixing and single-screw extrusion. Tensile testing (at strain rates from 0.02 to 2) showed that both neat nylon and the nanocomposites exhibit strain rate hardening, with ultimate tensile strength (UTS), yield strength, and tensile modulus all influenced by strain rate. Critically, adding ZnONPs improved these mechanical properties, with the 2 wt% nanocomposite showing a 45% higher tensile modulus and a 26% higher UTS than neat nylon. Thermal stability was enhanced by the nanoparticles, as confirmed by thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) revealed a slight increase in glass transition temperature. A constitutive model effectively captured the nonlinear, strain rate-dependent behavior of both the base polymer and the nanocomposites. While thermal conductivity and diffusivity showed complex trends with increasing ZnONP content, the 2 wt% sample exhibited the highest conductivity and lowest diffusivity. Finally, the dielectric constant increased, and resistivity decreased, with higher ZnONP loadings.
