High-resolution extrusion printing of Ti3C2-based inks for wearable human motion monitoring and electromagnetic interference shielding

This work addresses two major challenges of MXene-based printing; that is, its low printing resolution (i.e., filament spreading >120%) and its inability to create structures with simultaneously high electrical conductivity and mechanical flexibility. We first report high-resolution extrusion pri...

Description
Summary:This work addresses two major challenges of MXene-based printing; that is, its low printing resolution (i.e., filament spreading >120%) and its inability to create structures with simultaneously high electrical conductivity and mechanical flexibility. We first report high-resolution extrusion printing of Ti3C2 and composite of Ti3C2/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The printing has a negligible filament spreading (
