Polyhedral Oligomeric Silsesquioxane/Multiwalled Carbon Nanotube (MWCNT/POSS) Hybrid Filler in Ethylene-Propylene-Diene Monomer/Styrene-Butadiene Rubber (EPDM/SBR) Nanocomposites: Preparation and Properties
In this study, ethylene-propylene-diene monomer/styrene-butadiene rubber (EPDM/SBR) nanocomposites were prepared using a two-roll mill mixing method, incorporating a hybrid filler of polyhedral oligomeric silsesquioxane (POSS) and multiwalled carbon nanotubes (MWCNT). The composites were evaluated for their cure characteristics, mechanical properties, abrasion resistance, compression set, swelling resistance, and crosslinking density. The results indicated that as the hybrid filler content increased, minimum torque, maximum torque, delta torque, and cure rate index decreased, whereas scorch time and optimum cure time increased. Mechanical testing revealed that tensile strength and stress at 100% elongation improved up to a filler concentration of 4 phr but declined beyond this level. Hardness and tear strength showed a continuous increase with higher filler loading, while elongation at break and rebound resilience decreased. Additionally, compression set increased with rising filler content. Swelling resistance and abrasion resistance were optimized at 4 phr of hybrid filler but deteriorated when the filler concentration exceeded this threshold.
期刊介绍：
The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
