Generally, higher loading amount of conductive carbon fillers is necessary for the development of thermally conductive rubber composites. However, high loading of conductive carbon black resulted in the significant decrement in mechanical properties such as tensile strength and elongation at break. To overcome this issue, development of three dimensional (3D) conductive networks at lower loading amount using the mixture of high aspect ratio one dimensional (1D, CNT) and two dimensional (2D, graphene) carbon nanofillers. In the present study, we have studied the effect of mixed carbon filler (1D+2D) system such as carbon nanotubes (1D) and expanded graphite (2D) on the mechanical and thermal properties of the rubber compounds such as butyl (IIR) and chloroprene (CR) composites. Dispersion state of the mixed carbon nanofillers in the rubber compounds is determined using FE-SEM. |
