Single-Walled and Multiwalled Carbon Nanotubes in Polybutadiene/Natural Rubber Composites Containing Silica for Conductive Green-Tire Application.

ABSTRACT: This study investigates the influence of commercial single-walled (SWCNT) and multiwalled carbon nanotubes (MWCNT) on the properties of natural rubber/polybutadiene composites containing silica for green tire applications. Composites were prepared on a laboratory scale using mixing protocols simulating conventional industrial methods, varying the nanotube content while keeping a fixed silica concentration of 55 phr. First, SWCNT and MWCNT were characterized in terms of atomic composition, number of defects, and morphology. Electrical conductivity measurements on nanocomposites indicate that SWCNT achieves the percolation threshold at lower concentrations (between 8 and 10 phr) compared to MWCNT (between 10 and 13.5 phr). Electrical conductivity in the range of antistatic properties (10
