Cellulose nanocomposite tough hydrogels: synergistic self‐healing, adhesive and strain‐sensitive properties

Abstract

Recent advancements are notable in electrically conductive hydrogels emulating human skin functions. However, a significant challenge remains: crafting a single conductive gel that integrates self‐healing, robust mechanical strength, and excellent electrical traits. Our innovation lies in a strong, lightweight, curable gel achieved through multiple coordination bonds between cellulose crystals and acid‐treated multi‐walled carbon nanotubes (MWCNTs) in a polymer network. Embedded MWCNTs act as dynamic bridges within a porous structure, giving exceptional mechanical performance. Reversible coordination interactions confer remarkable recovery and reliable mechanical and electrical self‐healing. Additionally, these ionic gels function as adaptable stress sensors, detecting significant movements like finger and joint motions. This work introduces multi‐walled carbon nanotube incorporated nanomaterials, that have good stretchability, high ion conductivity, remarkable self‐healing nature, and good stress sensitivity. Such properties hold promise for electronic sensors, wearable devices, and healthcare monitoring, unveiling a path to diverse applications. Our study addresses challenges and unlocks possibilities for materials that can adapt, withstand, and sense in innovative ways.This article is protected by copyright. All rights reserved.
