Boosting electrical and piezoresistive properties of polymer nanocomposites via hybrid carbon fillers: A review

Carbon nanofillers are widely used to blend with polymers for fabricating high-performance polymer nanocomposites (PNCs) toward structural, electronic and sensory material applications. However, it is generally of challenge to achieve significant property improvement by using single carbon nanofiller. Alternatively, using hybrid carbon nanofillers has been proved to be a facile and promising strategy to effectively boost electrical and piezoresistive properties of PNCs. This paper provides a state of the art review on the effects of hybrid carbon fillers on electrical properties of PNCs and corresponding applications in piezoresistive sensing scenarios. The effects of hybrid carbon nanofillers on electrical percolation threshold, electrical conductivities and piezoresistive sensitivity of PNCs are systematically discussed. [Display omitted]
