Electron beam crosslinked natural rubber/multiwalled carbon nanotube nanocomposite

The physical properties of the rubber blends are influenced by vulcanization and filler distribution. Normally, rubbers are vulcanized by systems based on sulfur or peroxide with the most common filler carbon black. Radiation can also produce crosslink densities like those obtained by sulphur cu...
