Evaluation of the properties of elastomeric compounds with the incorporation of graphene nanoplatelets through various mixtures processes

Year: 2024

Type: article

Abstract: Graphene nanoplatelets (GNPs) have emerged as promising additives for improving the properties of elastomeric compounds. This study investigates the influence of GNPs on styrene-butadiene rubber (SBR) formulations through a thorough assessment of rheological, mechanical, and thermal characteristics. Various mixing processes, including closed and open mixers, were employed to disperse GNPs effectively. Results demonstrate that the incorporation of GNPs accelerates vulcanization, increases crosslink density, enhances thermal conductivity, and improves mechanical strength in SBR compounds. Notably, open mixer processing yields superior dispersion and thermal conductivity compared to closed mixers. Additionally, GNPs mitigate the reduction in tensile strength observed during prolonged thermal aging. These findings highlight the multifunctional role of GNPs in elastomeric compounds and underscore the importance of dispersion techniques for optimizing their performance. Overall, this research contributes to advancing the understanding of GNPs as versatile additives for enhancing elastomeric materials, with potential applications across diverse industrial sectors.
