Piezoresistivity and strain-sensing behaviour of poly(butylene adipate-co-terephthalate)/multiwalled carbon nanotube nanocomposites

Abstract

The interconnectedness of the exfoliated multi-walled carbon nanotubes well dispersed in the PBAT matrix (TEM image; left) leads to strain-sensing properties at lower strains as illustrated by the variation of ΔR/R0 as a function of mechanical strain with time (right).
