Abstract
Electrically conducting silicone rubber composites were prepared by the incorporation of conducting
fillers including carbon black, carbon fibers and carbon nanotubes. Silicon/multi-walled
carbon nanotube (MWCNT) composites were produced by mechanical mixing. Glass beads
(GBs) were introduced to significantly improve the dispersion of MWCNTs in the silicone
matrix. The dispersion of MWCNTs in a silicone matrix is related to the ball-bearing effect of
the glass beads. The electrical conductivity of the high viscosity-silicone/MWCNT/GB composite
was approximately double that of the composite without glass beads due to the improved
distribution uniformity of MWCNTs in the silicone matrix. In addition, the presence of glass
beads in the silicone matrix improved the mechanical properties, such as the tensile strength and
elongation at break as well as the electrical conductivity.
