Electrical and piezoresistive properties of hybrid nanocomposite films and tubes made of a segmented aliphatic polyurethane modified with multilayer graphene sheets (MLGSs), multiwall carbon nanotubes (MWCNTs), and hybrid mixtures of both, were investigated. Hybrid nanocomposites were fabricated at a total weight concentration ( ##IMG## [http://ej.iop.org/images/0964-1726/29/11/115021/smsaba9e6ieqn1.gif] {${\Phi _T}$} ) of 5 wt.%, with relative weight concentration of MLGSs with respect to MWCNTs ( ##IMG## [http://ej.iop.org/images/0964-1726/29/11/115021/smsaba9e6ieqn2.gif] {${\Phi _R})$} of 25%, 50% and 75%. The electrical conductivity of these films is dominated by the MWCNT network, observing electrical MLGS-MWCNT collaborative effects only for ##IMG## [http://ej.iop.org/images/0964-1726/29/11/115021/smsaba9e6ieqn3.gif] {${\Phi _R}$} = 25%. Dielectric impedance spectroscopy indicates that the nanocomposites displa...
