“…The disulfide bonds of the LA at 510 cm −1 observed in Raman spectra are largely broadened and shifted in the IE (Figure S1, Supporting Information), which is different from the split-shaped peaks observed in our previous research works. [13,14,21] It may be caused by forming the lithium-sulfur coordinate bonds (Li-S bonds) of the lithium bonds (Li-bonds). The co-polymerization of the LA and LiTFSI is proved by 1 H NMR spectra (Figure S2, Supporting Information).…”

Lipoic acid (LA), which originates from animals and plants, is a small biomass molecule and has recently shown great application value in soft conductors. However, the severe depolymerization of LA places a significant limitation on its utilization. A strategy of using Li‐bonds as both depolymerization quenchers and dynamic mediators to melt transform LA into high‐performance ionoelastomers (IEs) is proposed. They feature dry networks while simultaneously combining transparency, stretchability, conductivity, self‐healing ability, non‐corrosive property, re‐mouldability, strain‐sensitivity, recyclability, and degradability. Most of the existing soft conductors’ drawbacks, such as the tedious synthesis, non‐renewable polymer networks, limited functions, and single‐use only, are successfully solved. In addition, the multi‐functions allow IEs to be used as soft sensors in human–computer interactive games and wireless remote sports assistants. Notably, the recycled IE also provides an efficient conductive filler for transparent ionic papers, which can be used to design soft transparent triboelectric nanogenerators for energy harvesting and multidirectional motion sensing. This work creates a new direction for future research involving intelligent soft electronics.

“…The ionogels with such high healed stress and strain outperform most of the previously reported self-healable ionogels (Figure 4c and Table S3, Supporting Information). [20][21][22][48][49][50][51][52] Additionally, given that these reversible physical interactions (sacrificial bonds) can be readily reformed after being disrupted during stretching, the strong electrostatic interactions and hydrogen bonds are considered to be beneficial for fatigue resistance and self-recovery of the PEI/PAA/CMC ionogels. The excellent fatigue resistance of the PEI 0.06 /PAA 0.25 /CMC 0.01 ionogel was confirmed by 10 continuous tensile and compression cycling curves without any residence time (Figure S10, Supporting Information).…”

Ionogels have attracted intensive attentions as promising flexible conductive materials. However, simultaneous integration of excellent mechanical properties, high conductivity, outstanding self‐healing ability, and strong adhesiveness is still challenging. Here, an ingenious composition design is proposed to address this long‐standing challenge of ionogels. High‐performance PEI/PAA/CMC ionogels, consist of a loosely cross‐linked poly(acrylic acid) (PAA) network, dynamically cross‐linked network based on polycationic polyethyleneimine (PEI) and polyanionic PAA, and carboxymethyl cellulose (CMC) reinforcing filler, are formed in a deep eutectic solvent (DES) composed of choline chloride and urea. Benefiting from the loose PAA network and dynamic noncovalent interactions, ionogels with both highly enhanced mechanical robustness and excellent conductivity are obtained at high loading of DES, overcoming the strength‐ductility/conductivity trade‐off dilemma. By adjusting PEI/PAA mass ratio, the tensile strength and strain of PEI/PAA/CMC ionogels are effectively controlled in a wide range of 0.15–7.9 MPa and 232–1161%, respectively, while maintaining the desirable conductivity of ≈10−4 S cm−1. Besides, healed tensile strength over 2.1 MPa and adhesion strength up to 0.2 MPa are achieved for the PEI0.06/PAA0.25/CMC0.01 ionogel. The delicate design strategy provides a feasible approach to prepare ionogels with outstanding comprehensive performance, which have potential for applications in flexible electronics.

By seamlessly integrating the wearing comfortability of textiles with the biomechanical energy harvesting function of a triboelectric nanogenerator (TENG), an emerging and advanced intelligent textile, i.e., smart textile TENG, is developed with remarkable abilities of autonomous power supply and self-powered sensing, which has great development prospects in the next-generation human-oriented wearable electronics. However, due to inadequate interface contact, insufficient electrification of materials, unavoidable air breakdown effect, output capacitance feature, and special textile structure, there are still several bottlenecks in the road towards the practical application of textile TENGs, including low output, high impedance, low integration, poor working durability, and so on. In this review, on the basis of mastering the existing theory of electricity generation mechanism of TENGs, some prospective strategies for improving the mechanical-to-electrical conversion performance of textile TENGs are systematically summarized and comprehensively discussed, including surface/interface physical treatments, atomic-scale chemical modification, structural optimization design, work environmental control, and integrated energy management. The advantages and disadvantages of each approach in output enhancement are further compared at the end of this review. It is hoped that this review can not only provide useful guidance for the research of textile TENGs to select optimization methods but also accelerate their large-scale practical process.
