摘要

To investigate the influence of the second filler on piezoresistive properties of the composites, silica (SiO_2) and carbon black (CB) as the insulating and conductive particles were incorporated into the carbon nanotube (CNT)/silicone rubber (SR) composites. Both SiO_2 and CB can serve as "seesaw" to support the CNT, but their effect on the piezoresistivity of CNT/SR composites was remarkably different. Besides, the introduction of SiO_2 and CB has a distinct CNT aspect ratio (AR) effect on the piezoresistivity. Lower AR endows higher piezoresistivity in the (SiO_2-CNT)/SR composites, but higher AR is more favorable for the (CB-CNT)/SR composites.
