Optimization of thermoplastic elastomer nanocomposites: Effect of SiC nanoparticles on PA6/NBR mechanical properties
Abstract Thermoplastic elastomers (TPEs) are widely used due to their unique combination of elasticity and processability. However, optimizing their mechanical properties remains a challenge. This study investigates nanocomposite TPEs based on polyamide 6 (PA6), nitrile butadiene rubber (NBR), and s...

| description | Abstract Thermoplastic elastomers (TPEs) are widely used due to their unique combination of elasticity and processability. However, optimizing their mechanical properties remains a challenge. This study investigates nanocomposite TPEs based on polyamide 6 (PA6), nitrile butadiene rubber (NBR), and silicon carbide (SiC) nanoparticles. The addition of SiC nanoparticles enhances tensile strength while reducing impact resistance. Conversely, increasing NBR content improved impact strength but lowered tensile strength. Using response surface methodology (RSM), we identified an optimal formulation of 30 wt.% NBR and 3 wt.% SiC, achieving a tensile strength of 56.1 MPa and an impact strength of 109 J/m. Morphological analysis confirmed that SiC nanoparticles reduced the NBR droplet size, leading to better stress transfer. These optimized nanocomposites demonstrate potential for high‐performance applications such as industrial sealants and automotive components. Highlights TPE nanocomposites based on PA6/NBR/SiC were prepared using an internal mixer. Using RSM, composition with maximum tensile and impact strength was determined. NBR content showed a positive effect on the impact strength. SiC nanoparticles content positively affected the tensile strength. At optimal composition, nanoparticles were uniformly dispersed in the matrix. |
