RUBBER NANOCOMPOSITES BASED ON NATURAL RUBBER/ BUTADIENE RUBBER BLEND AND MULTI WALLED CARBON NANOTUBES

Abstract

The outstanding properties of carbon nanotubes have generated scientific
and technical interests in the development of nanotube-reinforced polymer
composites. Therefore, a new mixing method for getting we investigated a novel
mixing approach for achieving a good dispersion of multiwalled carbon
nanotubes (CNTs) in a rubber blend Natural rubber/ Butadiene rubber was
studied. In this approach, the CNTs were incorporated of Natural rubber solution
and Butadiene rubber solution which ratio is 70:30 phr. The rubber
nanocomposites prepared by such method exhibit significantly enhanced
physical properties already at very low nanotube concentrations. The high aspect
ratio of the carbon nanotubes enabled the formation of a conductive percolating
network in these composites at concentrations below 3 wt.%
