Properties of Rubber Composites Having Surface Modified Carbon Black Fillers
Rubber reinforcing carbon black N330 was surface modified by acid, base treatment and physical activation in CO2 to different degrees of burn-off. SBR (Styrene-Butadiene Rubber) rubber composites having acid and base treated carbon blacks showed improved tensile strength and elongation at break when compared to that filled by raw N330 carbon black. The porosity of CO2 activated carbon blacks is turned out to be an increasing function of the degree of burn-off. Due to the surface disorder after activation, filler-polymer interaction was promoted at lower carbon blacks loading ratio. But with increasing filler loading, the mechanical properties of rubber composites decreased extremely. The Electromagnetic Interference (EMI) shielding characteristics of SBR rubber composites filled by activated carbon blacks at 74% yield exhibited much better EMI shielding effectiveness than those having raw carbon blacks due to the formation of a more developed continuous conductive filler network in the rubber matrix.
