The effect of carbon nanotube on curing and mechanical properties ofEPDM/SBR elastomeric blend

Curing and mechanical properties of rubber nanocomposites filled with carbon nanotubes (CNTs)were investigated, using a ۵۰/۵۰ wt% blend of ethylene propylene diene monomer (EPDM) andstyrene-butadiene rubber (SBR) as the polymer matrices. The nanocomposites were prepared throughmelt mixing and cured using a sulfur-based curing system. The impact of varying CNT concentrationson curing characteristics and mechanical properties of the prepared samples were evaluated. Obtainedresults indicated that the addition of CNTs caused reduction of scorch time and enhances the torqueof rheometry. Also, it significantly enhances the mechanical properties of EPDM/SBRnanocomposite, These enhancements are attributed to the excellent reinforcing capability of CNTs,which facilitate effective stress transfer within the rubber matrices. The findings highlight thepotential of CNT-reinforced rubber nanocomposites for applications demanding superior mechanicalperformance.
