Abstract Flexible and stretchable ion‐conductive elastomers have shown promising applications in wearable flexible sensor devices, biopotential detection, electroluminescent other areas. However, the currently employed gel‐based materials encounter issues such as solvent volatilization or leakage. Herein, there is an urgent requirement to develop a solid‐state ionic conductor material that both safe reliable, free from of liquid Here, study reports elastomer with excellent mechanical properties high conductivity based on synergistic strategy multiple interaction forces. The ion−conductive exhibits (1.42 × 10 −4 S cm −1 at 25 °C), superior stretchability (≈1550% elongation) strength (1.48 MPa). Moreover, resilience possesses self‐healing ability. sensor, prepared comprehensive performance, not only demonstrates strain sensitivity but also captures high‐quality epidermal signals human body detection. Additionally, can serve electrode devices for applications. It believed provide novel opportunities advancement soft ionotronics.

Engineering Robust Conductive Hydrogel Sensors with Enhanced Mechanical Properties and Practical Applicability

Macromolecules, Год журнала: 2024, Номер 57(10), С. 4737 - 4746

Опубликована: Май 8, 2024

Conductive hydrogel represents an important component in the modern electronic industry. However, huge challenges still remain because general hydrogels fail to satisfy simultaneous high mechanical properties, excellent conductivity, and real-world tasks, which severely restrain their practical applications. To overcome challenge, herein, a robust PVA/PEI/SG [poly(vinyl alcohol)/polyethylenimine/sodium glycinate] has been successfully engineered using multiple physical bond networks including microphase areas of PVA alone hydrogen bonds among PVA, PEI, SG. Besides its also exhibits sensitivity, stable signal output capability. Moreover, upon use as sensor, it can smoothly accomplish real-time tasks like completing operation smartphone make call, writing "haust" on screen, detecting human joint bending motions, to-and-fro movement arm. The successful synergy attractive performance enables potential conductive device for flexible electronics.

Solvation Chemistry Enables Eutectogels with Ultrahigh Autofluorescence, Toughness, and Adhesion under Extreme Environments

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Abstract Compared to conventional gels, eutectogels encompassing deep eutectic solvents (DESs) circumvent the shortboards including poor temperature resistance, high cost, and undesired toxicity. However, existing suffer weak intra‐ interchain interactions, which culminates in vanishing autofluorescence, mechanic feeble adhesion. Although myriad strategies have been proposed boost polymer/polymer interactions within processes are time‐consuming, not suitable for mass production or emergent deployment. Herein, deal with it, a facile solvation chemistry is leveraged build dynamic rigid network via incorporating active polymer backbones DESs. Within these eutectogels, DESs play magnet‐like role, physically cluster chains together multiple noncovalent forces, thus intensifying DESs/polymer interactions. This bestows rare autofluorescence unprecedentedly strength, toughness, adhesion among reported analogues, even harsh conditions. Moreover, mechanism of fully scrutinized first time. It believed that this strategy can be easily expanded orchestrations other soft materials.
