Resumen o descripción

This work reports the electrical and piezoresistive responses of thin polymer films made of polysulfone

(PSF) modified with 0.05–1% w/w multi-wall carbon nanotubes (MWCNTs). MWCNT/PSF films are fabricated

by solution casting and their electric and piezoresistive responses are evaluated. Gage factors are

measured for films with 0.2–1% carbon nanotube weight loadings. The films are then bonded to macroscopic

aluminum specimens and evaluated as strain sensing elements during quasi-static and cycling

tensile loading. Excellent piezoresistive capabilities are found for films with MWCNT loadings as low as

0.5% w/w, which renders them functionality as strain gages.
