Hydrophobic TPU/CNTs-ILs Ionogel as a Reliable Multimode and Flexible Wearable Sensor for Motion Monitoring, Information Transfer, and Underwater Sensing

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(27), P. 35626 - 35638

Published: June 29, 2024

Ionogel-based sensors have gained widespread attention in recent years due to their excellent flexibility, biocompatibility, and multifunctionality. However, the adaptation of ionogel-based extreme environments (such as humid, acidic, alkaline, salt environments) has rarely been studied. Here, thermoplastic polyurethane/carbon nanotubes–ionic liquids (TPU/CNTs-ILs) ionogels with a complementary sandpaper morphology on surface were prepared by solution-casting method simple template, hydrophobic flexible TPU/CNTs-ILs sensor was obtained modification using nanoparticles modified cetyltrimethoxysilane. The hydrophobicity improves environmental resistance sensor. exhibits multimode sensing performance can accurately detect response signals from strain (0–150%), pressure (0.1–1 kPa), temperature (30–100 °C) stimuli. Most importantly, be used not only wearable monitor human motion but also for information transfer, writing recognition systems, underwater activity monitoring. Thus, offers new strategy electronics, especially applications environments.

Published: May 25, 2023

Abstract To efficaciously decrease dielectric loss while still synchronously harvesting a high constant ( ε ′) and breakdown strength E b ), as well good mechanical properties in silicon (Si)/poly(vinylidene fluoride) (PVDF), this work, the core@shell structured Si@silicon dioxide (SiO 2 ) particles were first prepared via temperature oxidation, subsequently incorporated into PVDF to generate morphology‐dependent composites with high‐ ′ but low loss. The SiO shell effects on morphology, dielectric, of explored. In comparison pristine Si/PVDF, Si@SiO /PVDF presents significantly suppressed boosted because interlayer not only efficiently blocks connection between raw Si greatly impedes long‐range charges migration even at filler loadings, also obviously improves compatibility interfaces which promotes fillers' uniform dispersion host matrix, thus leading enhanced properties. fitting result by Havriliak–Negami equation theoretically elucidates interlayer's suppression effect charge behavior composites. More importantly, can be turned tailoring thickness. simultaneously performances shows promising uses electrical microelectronics industries.
