Abstract

See full text

Disclosed is an elastomer-conductive filler composite with improved dielectric properties. The composite includes conductive fillers and an ionic liquid dispersing the conductive fillers. The ionic liquid is used as a dispersant to effectively enhance the dispersion of the conductive fillers, achieving a high dielectric constant and a low dielectric loss of the composite without deteriorating the physical properties of the conductive fillers. The use of the ionic liquid can reduce the number of processing steps and the presence of the conductive fillers at a low concentration in the composite can minimize deterioration of the physical properties of the elastomer. Further disclosed is a method for producing the composite.
