Thermal Conductivities and Mechanical Properties of EPDM Filled with Modified Carbon Nanotubes

Abstract:

In this article, in order to improve the thermal conductivities and mechanical properties of EPDM filled with carbon nanotubes, phenol formaldehyde resin is used to coat to the surface of carbon nanotubes so as to improve the dispersion in rubber matrix and the combination with EPDM. The results show that with the ratio of CNTs and PF increased, the thermal conductivities of carbon nanotubes/EPDM composites show upward trend. Besides, with the increase of filler content, thermal conductivities of composites are improved as well. However, the mechanical properties of composites are declined. Therefore, more effective methods of modification of carbon nanotubes should be attempted, and more experiments should be conducted to improve mechanical properties of filled EPDM and ensure the high thermal conductivities at the same time.
