Dual filler (organoclay and carbon black) loaded emulsion polymerized styrene butadiene rubber (E-SBR)
based nanocomposites were synthesized by melt blending. Three different organic ally modified clays
(viz. Cloisite 15A, Cloisite 20A and Cloisite 30B) were used for the present study. To disperse different
organoclays selectively in the rubber matrix, oil extended carboxylated styrene butadiene rubber (XSBR)
was used as a compatibilizer between organoclay and the nonpolar SBR. Wide angle X-ray diffraction
analysis (WAXD) and high resolution transmission electron mic roscopic (HR-TEM) analysis of the nano-
composites revealed that the organoclays were intercalated and delaminated in the elastomer matrix in
the presence of carbon black (CB). Different organoclay loaded SBR compounds show improvement in the
overall properties such as curing features, mechanical, thermal, abrasion resistance and dynamic
mechanical properties compared to the neat SBR. Among the three different hybrid nanocomposites, Cloi-
site 30B filled SBR compound in the presence of CB show superior properties
