| Abstract Scope |
Conductive composites used in flexible circuits have a wide range of applications, such as wearable sensors, proximity sensors, and pressure sensors. Polymers and carbon nanotubes (CNTs) are representative materials in conductive composites. Polymers provide flexibility, while CNTs impart electrical properties, making them suitable for this purpose. In this study, conductive composites were produced by blending thermoplastic polyurethane (TPU) with CNTs and investigating their electrical properties using fused filament fabrication (FFF). The melting mixing method was used for composite fabrication. As the wt% of CNTs increased, the electrical resistance decreased, and the resistance showed a decreasing trend with increasing applied voltage. In cases where the wt% of CNTs was low, the resistance decrease with increasing voltage was relatively high, which can be explained by the tunneling conduction mechanism in the conductive composite. |
