Highly Ordered Thermoplastic Polyurethane/Aramid Nanofiber Conductive Foams Modulated by Kevlar Polyanion for Piezoresistive Sensing and Electromagnetic Interference Shielding

Highlights Kevlar polyanionic chains induced the formation of highly ordered porous thermoplastic polyurethane foams with adjustable pore sizes. A tiny amount of Ti 3 C 2 T x MXene was performed as reducing agent for the electroless deposition of copper nanoparticles. The conductive foam reinforced by aramid nanofibers exhibited excellent piezoresistive sensing and electromagnetic interference shielding performance.
