Abstract
Composite particles may be produced by drying slurries containing silica particles and graphenic carbon particles in a liquid carrier. Elastomeric formulations comprising a base elastomer composition and the silica-graphenic carbon composite particles are also disclosed. The formulations possess favorable properties such as increased stiffness and are useful for many applications such as tire treads.
