| Abstract Scope |
Multifunctional polymer composites capable of sensing damage, monitoring structural health, and providing shape-memory actuation are attracting increasing interest for smart structures and soft robotics. This work investigates carbon nanotube (CNT)-reinforced thermoplastic polyurethane (TPU)/acrylonitrile butadiene styrene (ABS) nanocomposites designed to combine the flexibility of TPU with the stiffness of ABS. Microstructural characterisation reveals selective CNT localisation within the TPU phase, enabling simultaneous enhancement of mechanical, electrical, and thermal properties. The electromechanical response was systematically evaluated under monotonic and cyclic loading, demonstrating sensitive piezoresistive behaviour. In-situ X-ray computed tomography further correlates damage evolution with electrical resistance, highlighting the potential for structural health monitoring prior to catastrophic failure. The composites also exhibit improved shape-memory performance with enhanced stress recovery. This study demonstrates the potential of CNT-reinforced TPU/ABS nanocomposites for next-generation multifunctional engineering applications as they exhibit simultaneously sensing, damage monitoring, and actuation capabilities. |
