This investigation evaluated the results of incorporating copper-modified activated carbon into natural rubber sheets on their electrical and mechanical characteristics. copper-modified activated carbon was added at various concentrations (5, 10, and 15 parts per hundred rubber), resulting in a notable enhancement in density as confirmed by scanning electron microscopy (SEM). However, the addition of copper-modified activated carbon led to a deterioration in several mechanical properties, including hardness, tensile strength, elongation at break, and rip strength, with the most significant decline observed in tensile strength. Atomic force microscopy (AFM) analysis revealed that copper-modified activated carbon addition in natural rubber sheets exhibited enhanced electrical properties compared to those containing only activated carbon. The findings suggest that these rubber sheets offer a promising balance between dielectric constants and mechanical durability, making them potential candidates for applications demanding flexible sensors and electrostatic discharge protection.
