Investigation of directional effects on the electrical conductivity and piezoresistivity of carbon nanotube/polypropylene composites obtained by extrusion 

 -  J Mater Sci, p.1-17, 2021 .
<br/><br/> The electrical conductivity and piezoresistivity of multiwall carbon nanotube (MWCNT)/polypropylene (PP)composites obtained by extrusion are investigated, with particular attention to the possible directional effects generated during the extrusion process. This is accomplished by investigating the electrical and electromechanical responses of the nanocomposites at three MWCNT weight concentrations (3, 4 and 5 wt
