Resumen

The tensile and cyclic piezoresistive behavior of multiwall carbon nanotube (MWCNT)/SPU composites were investigated as a function of the RS content (15%, 30% and 50%) and MWCNT concentration (2 wt.%, 4%wt% and 6 wt.%). SPUs with 15% and 30% RS were elastomeric (600% and 800% respectively), but that with 50% RS the strain to failure was only about 30%. The incorporation of MWCNTs into the SPUs increases the stiffness but also reduces their elongation at break and tensile strength. Composites with 15% and 50% RS, at the same MWCNT concentration, showed higher electrical conductivity than those with 30% RS. Regardless of the relative amount of rigid segments, 4 wt.% and 6 wt.% MWCNTs composites exhibited electrical conductivities from 10"8 to 10"3 S/cm. The tensile piezoresistive behavior is strongly dependent on the relative amount of rigid segments of the polymer and MWCNT concentration. Upon loading, changes in electrical resistance are of the order of 1500 times the initial resistance for very flexible composites (15% RS), while such changes are only about 15 times for rigid composites with 50% RS. The results show that the piezoresistive response of the first loading-unloading cycle behave very differently to the subsequent cycles, but became reproducible as the number of cycles increases. Flexible composites with 15% or 30% RS and 2-4 wt.% MWCNTs show the most promising results as sensors of large cycling strains.
