Electrically conducting silicone rubber composites were prepared by the incorporation of conducting fillers including carbon black, carbon fiber, and carbon nanotubes. Herein, silicone/multi-walled carbon nanotube (MWNT) composites were produced by mechanical mixing, where glass beads (GBs) were introduced to significantly improve the dispersion of MWNTs in a silicone matrix. The dispersion of MWNTs in a silicone matrix is related to the ball-bearing effect of GBs. The electrical conductivity of the silicone/MWNT/GB composite was approximately two times higher than that of the composite without GBs due to the improved distribution uniformity of MWNTs in the silicone matrix. In addition, the presence of GBs in the silicone matrix improves the mechanical properties, such as the tensile strength and elongation at break as well as the electrical conductivity.

Keywords:multi-walled carbon nanotube;silicone rubber;glass bead;dispersion uniformity;electrical conductivity
