Recent interest in stretchable electronics and wearable technology has driven the demand for flexible strain sensors. Conductive polymer composites have gained increasing attention as sensors owing to their potential advantages. In this study, effect of different matrices varying carbon nanotube (CNT) loadings by fabricating sandwich‐structured polydimethylsiloxane (PDMS)/CNT thermoplastic polyurethane (TPU)/CNT is investigated using a solution mixing process. The uniform dispersion CNTs both PDMS/CNT TPU/CNT nanocomposites facilitates proper electrical conductivity. PDMS/CNT6% TPU/CNT6% demonstrate higher linear performance under monotonic strains up 20% compared other samples. cyclic stress–strain tests, perform more efficiently an immediate response sensors, which exhibit shoulder peak phenomenon. This phenomenon occurs due mechanical properties hysteresis TPU matrices. these findings, it revealed that relative standard deviation % (RSD%) values are smaller than TPU/CNT, confirms considerable repeatability Furthermore, offers effective detection human body motion, such finger joint movements with bending angles wrist at various rates. present guideline provided material selection

Flexible nanocomposites incorporating nanofibrillated cellulose (NFC) hold significant promise for thermal management applications. However, their heat dissipation performance is primarily constrained by the interfacial resistance (Rbd). In this work, 1-pyrenemethylamine hydrochloride (PyNH2) noncovalent functionalized graphene subsequently self-assembled with NFC through a vacuum-assisted filtration technique. PyNH2 could not only stabilize π–π conjugation but also interact via hydrogen bonding. The prepared layered-structure achieve conductivity of 11.32 W·m–1·K–1 low filler content just 5 wt %. Utilizing effective medium approximation (EMA) method and two-dimensional X-ray scattering techniques, we know that satisfactory mainly attributed to pyrene functionalization engineering-induced Rbd high orientation degree graphene. Undoubtedly, study provides experimental theoretical guide fabrication conductive in near future.
