Abstract Scope |
Soft and stretchable materials with high electrical conductivity have broad applications in soft electronics, sensors, and robotics. One of the most important methods to create such soft and stretchable conductive materials is by dispersing conductive nanofillers in an elastomer matrix. But the limitations of such an approach include the uncontrolled aggregation of nanofillers and difficulty in creating well-defined 3D structures and devices. To address those issues, in this research, we integrate a sustainable thermoplastic elastomer (TPE) with conductive carbon nanomaterials into functional nanocomposites. More importantly, we demonstrate pellet-extrusion 3D printing of such soft nanocomposites into well-defined 3D structures. The effects of the nanofiller loading, nanofiller morphology, and processing conditions on the physical properties of the nanocomposites are investigated. We also systematically investigate the strain-dependent electrical conductivity of such nanocomposites. The potential applications of such soft, stretchable, and 3D-printable nanocomposites in strain and motion sensors are also successfully demonstrated. |
