The rapid growth of strain sensors in cutting-edge applications, including wearable human–machine interfaces, electronic skins, soft robotics, and advanced healthcare, has greatly heightened the demand for high-performance hydrogels. In this report, we demonstrate a multifunctional, highly stretchable, and robust conductive hydrogel composed of polyacrylamide (AM), 2-hydroxyethyl acrylate (HEA), and lithium chloride (LiCl) reinforced by zeolite imidazolate frameworks-8 (ZIF-8) through a one-pot free radical polymerization method. The synergy of electrostatic interactions between the AM-HEA polymer chain and nanoporous ZIF-8 enhances the mechanical properties, while the abundant hydrogen bonds originating from the polarized surface of ZIF-8 also introduce multifunctionality to the nanocomposite hydrogel. Tuning the composition of ZIF-8 within the hydrogel matrix results in the attainment of outstanding properties such as excellent stretchability of 808%, high toughness of 453.5 kJm−3, and minimal hysteresis as low as 2.6%. Notably, the nanocomposite hydrogel displays strong adhesion, self-healing properties, and resilience in freezing temperatures down to − 20 °C. Furthermore, the as-developed strain sensor exhibits relatively high sensitivity with a gauge factor of 2.98 across a wide dynamic range, along with fast response and recovery times of 280 ms and 330 ms, respectively. The multifunctionality and electromechanical properties of ZIF-8 enhanced high-performance hydrogel hold promise for its application as a wearable, flexible, and stretchable strain sensor for detecting human physiological activities and providing vital biomechanical information for health assessment.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
