Conducting polymer composites become increasingly significant for variety of applications in electrical and mechanical devices. Poly (ionic liquid)s (PILs) achieved remarkable interest in this field for the unique properties and added advantages in mechanical stability, improved processability, durability, and spatial controllability. Carbon nanotube (CNT) as filler material to the matrix of PIL can achieve the desired composite material with improved electrical and mechanical properties. In this work, we developed PIL-CNT nanocomposites by using quaternary ammonium type IL monomer and multiwall CNT. Their mechanical, thermal and thermomechanical properties have been studied and future possibilities of employing in electromechanical devices have been explored.
