Dynamic Mechanical Properties of Natural Rubber Vulcanizates with Different Carbon Nanotubes-Loaded

摘要

The dynamic properties of a natural vulcanized rubber containing different carbon nanotubes-loaded were studied for dynamic tensions of amplitude varying greatly. It was shown that both the elastic responses and viscosity change with amplitude of oscillation and with concentration of carbon nanotubes. The degree of crosslinking was enhanced by addition of filler and improved by increasing amount of filler. Decomposition mechanism of natural rubber is not altered by addition of filler, but the decomposition of temperature increased, which meant that the additional of filler enhanced thermal stability of the material.
