摘要

Abstract

In recent years

flexible ionic conductors have made remarkable progress in the fields of energy storage devices and flexible sensors. However

most of these materials still face challenges such as the difficult trade-off between stretchability and high mechanical strength

as well as insufficient ionic conductivity. Among them

polymerizable deep eutectic solvents (PDES)

which possess both hydrogen bond network construction capabilities and ionic conduction properties

have demonstrated great advantages in the synthesis of flexible ionic conductors. Herein

we report an ionic conductive elastomer (ICE) named PCHS-

based on PDES composed of 2-(methacryloyloxy)-

-trimethylammonium methyl sulfate (MA-MS)

choline chloride (ChCl)

and 2-hydroxyethyl acrylate (HEA). The introduction of MA-MS enabled the polymer network to form ab

undant hydrogen bonds

endowing PCHS-

with excellent mechanical strength

high transparency

favorable ionic conductivity

self-adhesiveness

and self-healing efficiency. When used as a strain sensor

the PCHS-

exhibits highly sensitive strain response

along with good stability and durability

allowing it to accurately monitor the movement of human body parts such as fingers

wrists

elbows

and knees. Additionally

owing to the enhanced ionic mobility at higher temperatures

this material also possesses excellent temperature sensing performance

enabling the fabrication of simple temperature sensors that can sensitively respond to temperature changes. This research provides new strategies for the practical applications of flexible electronic devices in fields such as wearable health monitoring and intelligent human-machine interaction.
