摘要
In order to improve interface properties of carbon black (CB)/silicone rubber (SR) composite materials, 1-allyl-3-methylimidazolium chloride (IL) was used to modify CB. A novel polymer-based flexible piezoresistive composite was prepared by mechanical mixing of SR and IL modified CB, and their piezoresistive properties were carefully characterized. A well dispersity and CB-IL encapsulation structure is observed by morphology characterization. In electrical test, the SR/CB-IL composites show lower percolation threshold compared with SR/CB composites. The SR/CB-IL composite with 6% of CB-IL shows higher piezoresistivity, better repeatability and shorter relaxation time due to the plasticizing effect of IL and ion exclusion and attraction effect. The results suggest that the SR/6CB-IL composites provide a new route toward fabrication of flexible piezoresistive sensors and wearable electronic devices. © 2017, Editorial Board of Polymer Materials Science & Engineering.
