Environmentally tolerant high-adhesion conductive eutectogels

Abstract

This study presents the development of environmentally tolerant, high-adhesion conductive eutectogels based on poly(N-hydroxyethyl acrylamide) (PHEAA) based eutectogels. The eutectogels were synthesized via a one-pot polymerization process, resulting in materials with exceptional mechanical properties, including high stretchability, tear resistance, and self-recovery capabilities. The eutectogels exhibited strong adhesion to various substrates, making them suitable for flexible sensor applications. Their non-volatile nature and thermal stability provided outstanding environmental tolerance, maintaining flexibility across a wide temperature range. Additionally, the eutectogels demonstrated high ionic conductivity and precise responsiveness, enabling their use in strain sensors and real-time electrocardiogram (ECG) monitoring. The results highlight the potential of PHEAA/DESs eutectogels for applications in flexible electronics, healthcare monitoring, and smart materials.
