Strain sensing behaviors of stretchable conductive polymer composites loaded with different dimensional conductive fillers

Herein, we investigate the dependence of the strain sensing behaviors of isoprene rubber (IR) based conductive composites on filler dimensionality. It is found that carbon black (CB)/IR composites display ultrahigh strain sensitivity and good recoverability since CB-networks are easily broken under stretching and fast rebuilt under releasing. However, the drawback of CB/IR composites is the high electrical percolation threshold (8.01 phr),...
