Abstract

Abstract The present study investigates the effect of thermooxidative and photooxidative aging on the mechanical and bactericidal properties of elastomer nanocomposites (ENs) based on Nanobent ZR2. The mechanical properties and morphologies were analyzed before and after aging. The addition of nanoparticles had a significant effect on the mechanical properties of ENs. Samples containing Nanobent exhibited higher tensile strength before and after aging compared to the reference composition. The addition of nanoparticles attenuated elastomer aging at elevated temperatures and ultraviolet light. Aged nanocomposites showed an inhibitory effect on the growth of bacteria and yeasts. Antibacterial and antifungal activity was only partially reduced after aging using physical methods compared to the activity of probes without aging. Scanning electron microscopy micrograph analysis showed different rough but homogeneous structures, confirming the uniform dispersion of the modified nanoparticles in the elastomer matrix as well as the retention of mechanical properties after the aging process.
