Structural conductive carbon nanotube nanocomposites for stretchable electronics

Abstract Carbon nanotube (CNT) nanocomposites have been widely used for electronic devices because of their high conductivity and ease processing. However, these limited functionality rigid intrinsic mechanical properties. In this study, we fabricated a stretchable serpentine structure using CNT nanocomposite with carboxymethyl cellulose binder. For flexible mold, polydimethylsiloxane (PDMS) was cast by the 3D printer. The slurry squeegeed into serpentine-patterned PDMS mold. Fourier-transform infra-red spectroscopy scanning electron microscopy were to analyze material properties 15–45 wt% CNTs. We analyzed grid current-voltage curves, strain resistance values, Joule heating effect. Next, developed structural electrode (SCNE) that insulated PDMS, induced skin-warming effect heating. Furthermore, light emitting diodes (LEDs) implanted in series T-shaped linear SCNE, which had greater stretchability. nine LEDs embedded SCNE successfully operated applying 20 V during bending structure. Finally, serpentine-shaped SCNEs serially-implanted programmed unison beat song.
