摘要

Abstract

Conductive hydrogels with high mechanical strength

good adhesion

and high sensitivity are highly demanded for wearable electronics. A multifunctional hydrogel based on 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and acrylic acid (AA) was synthesized

via

free-radical polymerization. The system incorporates dynamic hydrogen bonds from guanine–cytosine (G–C) base pairs and homogeneously dispersed carbon nanotubes (CNTs) modified using a dual-ionic liquid strategy. Short-chain (C

) and long-chain (C

) imidazole-based ionic liquids act synergistically to exfoliate and stabilize CNTs

facilitating uniform dispersion and strong interfacial bonding. Owing to the continuous conductive pathways formed by the CNTs

the hydrogel exhibited enhanced electrical conductivity with a gauge factor of 5.61

together with excellent short-term cyclic stability and responsiveness for monitoring dynamic human motions. The combinat

ion of covalent cross-linking

reversible hydrogen bonding

and reinforced nanofillers endows the hydrogel with high stretchability

good adhesion (5.5 kPa)

and superior fatigue resistance

showing great potential for use in flexible wearable bioelectronics.
