Effect of functionalized nanotubes with HNO3 on electrical sensory properties of carbon nanotubes/polyurethane composite under elongation

Original language description

Thermoplastic polyurethane elastomer PU/MWCNT-N network (Buckypaper) composite was prepared and tested as tensile strain sensing element by measurement of its macroscopic resistance. In the first step MWCNTs aqueous dispersion was filtered thought PU filtering membrane prepared by technology of electrospinning. The filtering membrane remains as a part of final composite when this filter-supported MWCNT-N network is attached to the surface of PU tensile test specimens by technology of compression moldingand the filter is transformed to form of PU adhesive film. The composite can sustain large deformation and the stain can be effectively detected by resistance measurement in real time of deformation. The response is sensitive, reversible and repeatable.Finally, the sensitivity of PU/MWCNT-N sensoric unit was significantly improved by CNT oxidation by HNO3 acid. This enhancement was quantified by Gauge factor, GF. Its value, for example, increase from 9.5 at tensile strain ~9% for pure
