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.
Des particules composites peuvent être produites par séchage de boues contenant des particules de silice et des particules de carbone graphénique dans un support liquide. L'invention concerne également des formulations élastomères comprenant une composition d'élastomère de base et les particules composites de carbone graphénique-silice. Les formulations possèdent des propriétés favorables telles qu'une rigidité accrue et sont utiles pour de nombreuses applications telles que des bandes de roulement de pneumatique.
