The wettability, breathability, and softness of fabrics are difficult to effect synergistically, so they cannot meet the requirements of personal comfort. Here, inspired by some amazing superhydrophilic structures in nature, a synergistic strategy is reported to create a novel Bola quaternary ammonium polyether polysiloxane (BQPEPS) with a water transport channel and softness performance with a unique inverted U shape, overcoming previous limitations. The results showed that the friction coefficient, bending rigidity, and softness were 0.153, 39.75 mN m, and 553 mN, respectively, which are better than those of commercially available products of two other structures. After 40 cycles of washing, the smoothness, stiffness, and softness of the BQPEPS-treated fabrics remained at 88%, 67.7%, and 63.5%, respectively. Moreover, the total wetting time of the BQPEPS-treated fabrics was less than 1 s, and the water vapor transmission was 792 g m–1 in 24 h. Overall, the successful synthesis of Bola polysiloxane should provide personal comfort and thereby exhibit great potential in practical applications.

Novel luminescent and amorphous La2O3–ZrO2:Eu3+ (LZE) nanofibrous membranes with robust softness are fabricated for the first time via a facile electrospinning technique. By incorporating zirconium oxide, the as-prepared lanthanum oxide nanofibrous membranes can be dramatically changed from extreme fragility to robust softness. Meanwhile, the softness and luminescent performance of LZE nanofibrous membranes can be finely controlled by regulating the doping concentration of zirconium oxide and europium in lanthanum oxide nanofibers. Additionally, the crystal structure analysis using X-ray diffractometer and high resolution transmission electron microscopy measurements have confirmed the correlation between the amorphous structure and softness. Furthermore, LZE membranes show the characteristic emission of Eu3+ corresponding to 5D0, 1, 2–7F0, 1, 2, 3, 4 transitions due to an efficient energy transfer from O2− to Eu3+. The LZE nanofibrous membranes with the optimum doping Eu3+ concentration of 3 mol% exhibit excellent softness and luminescent properties, which make the materials to have potential applications in fluorescent lamps and field emission displays.

As the living standard improves, disposable sanitary and household paper requires not only softness or easy to fluff in a dry state, but also good antibacterial property. In this study, a series of alkyl quaternary ammonium salts ( AQAS ), a kinds of antibacterial-debonding agents, were synthesized by using a two-step process. The SN2 nucleophilic substitution reaction was designed between triethanolamine and sulfoxide chloride, and followed subsequent quaternization by tertiaryamines with different long alkyl chains. The obtained products can be used as an antibacterial and softening/debonding agent for improving the performance of paper or fluff pulp. The results showed that these new compounds can endow antibacterial function and high softness to paper or control appropriate burst strength to fluff pulp. These AQAS products can be not only used in daily disposable sanitary products, but also have potential applications in other products such as glass spacer paper, advanced household paper, or antibacterial tissue products to prevent microbial contamination.

Conducting polymer hydrogels have been considered as promising materials for flexible sensors. The integrated performances of ultrasoftness, high deformation, mechanical robustness, conformal adhesion, and high sensitivity are of great importance for their applications in wearable sensors but still remains challenging. Herein, a highly deformable conducting polymer hydrogel with ultrasoftness, tear resistance, and self-adhesiveness is fabricated by incorporating poly(3, 4-ethylenedioxythiophene):poly(styrene sulfonic acid) (PEDOT:PSS) and silk sericin (SS) into a covalently cross-linked polyacrylamide (PAM) network. Owing to abundant noncovalent interactions among the folded SS chains, PAM chains, and PEDOT:PSS, the obtained hydrogel shows a low modulus (10.3 kPa), ultrastretchability (>2000%), particularly large biaxial strain (an areal strain of 1700%), high toughness (tearing energy of 2.5 kJ/m2), and good conformal adhesion. As a result, this hydrogel demonstrates superior strain-sensitivity (gauge factor = 13.8) in a broad strain range (2000%) and excellent sensing reproducibility. The hydrogel-based wearable sensor can be used for accurately monitoring large and tiny human movements in real time and serves as bioelectrodes for precise gathering of electrocardiography and electromyography signals, showing great potential for applications in flexible sensing devices.

A series of polyethylene glycol-linked Gemini fatty alcohol phosphate surfactants (GFAP) were prepared with long chain n -alkanol (C = 8, 12, 16, 18), polyethylene glycol (PEG-200, PEG-400, PEG-600, PEG-800, PEG-1000) and phosphorus oxychloride (POCl 3 ). The structure of the prepared surfactants was characterized by Fourier transform infrared spectrometer (FT-IR). The surfactants were employed for the modification of chrome-tanned leather. The morphological changes of chrome-tanned leather and modified chrome-tanned leather were observed by scanning electron microscopy (SEM). The relationship between the alkyl chain length and molecular weight of the PEG and the hydrophobicity, softness, mechanical strength of modified chrome-tanned leather was also discussed. The experimental results showed that the mechanical strength and softness of modified chrome-tanned leather were enhanced with an increase of alkyl chain length, while the hydrophobicity, mechanical strength and softness were decreased with an increase of molecular weight of the PEG. The hydrophobicity, mechanical strength and softness of modified chrome-tanned leather were optimized for an alkyl chain length of 16. Therefore, 16–200 Gemini phosphate surfactants with an alkyl chain length of 16 and a PEG molecular weight of 200 have a good comprehensive modification effect on Chrome-tanned leather, the tensile strength, tear strength and softness of modified chrome-tanned leather are 57.07 N mm −2 , 79.49 N mm −1 , 9.73 mm, respectively.

Achieving stable bioelectronic interfaces is hindered by inherent mechanical–electrochemical mismatches, limiting long-term device functionality in dynamic tissues. Current hydrogel-based bio-ionotronic devices face a fundamental trade-off: soft hydrogels lack sufficient ionic carriers, while ionic hydrogels compromise softness due to high cross-linking density. Here, we developed a biphasic ionic hydrogel (BIH) by integrating microgel-rich ionic reservoirs (microgel phase) into a continuous hydrogel matrix (CH phase) via hydrogen bonds. The microgel phase and CH phase of BIH work synergistically, reducing cross-linking density while maintaining the ion monomer content of the hydrogel. This synergistic structure decouples ionic storage from mechanical compliance, enabling ultrasoftness (2 kPa) and high ionic conductivity (8.55 S m–1), surpassing conventional ionic hydrogels. By tuning the microgel content, we increased the polymer network’s characteristic length, facilitating ion diffusion while maintaining structural integrity and reducing interfacial impedance. Demonstrations in real-time electromyography and mechanical motion sensing validated its potential for soft bioelectronics.

The inherent conflict between interfacial toughness and bulk energy dissipation in elastomers poses a challenge for achieving optimal adhesion. Here, this work reports a molecular design strategy for constructing poly(urethane-urea-thioctic acid) (PU-TA) elastomers with superior adhesive properties (adhesion strength of 611 ± 22 kPa and adhesion energy of 2723 ± 82 J m −2 ), high stretchability (8579%), and excellent softness (low Young's modulus of 147 kPa). This is realized via introducing multiple hydrogen bonds (H-bonds) into the PU-TA elastomers: The H-bonds at interfaces establish interfacial linkage, and the bulk H-bonds inhibit the chain segments, resulting in high fracture energy. Furthermore, a correlation analysis demonstrates that bulk energy dissipation dominates role key in regulation of adhesion energy compared with interfacial toughness. This molecular-level strategy provides a new sight into the design of superior adhesives suitable for diverse applications in the field of advanced packaging.

Polyurethane (PU) can be synthesized by replacing petrochemical polyols partially with lignin, thus improving the environmental benefit and the comprehensive performance of the foam. Herein, sulfomethylated Kraft lignin (SKL) is obtained by sulfonation of Kraft lignin (KL), and then it is used as filler to synthesize the sulfomethylated lignin-based flexible polyurethane foam (SLFPUF). The effects of SKL with different sulfonations on SLFPUF are explored. Thermogravimetric (TG) analysis shows that when the sulfonation is 0.286 mmol/g, the residual mass is 12.63 % that is higher (3.35 %) compared to the control group lignin-based flexible polyurethane foam (LFPUF), indicating better thermal stability. The support factor (SF) of SLFPUF-0.286 is 4.99, higher than that of LFPUF (1.89), showing good softness. The air flow of SLFPUF-0.286 is 756.9 Pa, lower than that of LFPUF (996.8 Pa), demonstrating good comfort. Moreover, the resiliency of SLFPUF-0.286 is 9.67 %, exhibiting a shape memory property, which has potential applications in the production of functional products with low resilience.

Ionic conduction is a crucial property for electronic biomaterials used in bioelectronics, as the biological systems rely on ions to conduct electricity. Currently, biomaterials-based functional hydrogels emerged as a promising building block for bioelectronics owing to their natural biocompatibility. However, two critical challenges faced by this type of hydrogel are their low ionic conductivity and unmatched mechanical modulus with soft tissues, which are inherently related to their complex biopolymer chains. Here, by mimicking the ion-accelerating effect of ion channel receptors in neuron membranes, a biomaterials-based ionic hydrogel (BIH) is developed, which offers a high ionic conductivity of 7.04 S m −1 , outperforming conventional chitosan, cellulose, agarose, starch, and gelatin based ionic hydrogels. The sulfonate groups and quaternary ammonium groups on zwitterionic side chains of poly (sulfobetaine methacrylate) (pSBMA) construct artificial cation and anion channels, respectively. The highly branched polymer structure of pSBMA reduces chain entanglement and lowers the Young's modulus of BIH to 7.2 kPa. Compared with traditional biomaterials-based hydrogels, the BIH simultaneously possesses excellent ionic conductivity and tissue-matching softness. Such BIH offers substantially higher quality of electrocardiogram and electromyogram signals than those of commercial electrodes.

Robust interfacial compliance is essential for long-term physiological monitoring via skin-mountable ionic materials. Unfortunately, existing epidermal ionic skins are not compliant and durable enough to accommodate the time-varying deformations of convoluted skin surface, due to an imbalance in viscosity and elasticity. Here we introduce a self-compliant ionic skin that consistently works at the critical gel point state with almost equal viscosity and elasticity over a super-wide frequency range. The material is designed by leveraging hierarchical hydrogen bond association, allowing for the continuous release of polymer strands to create topological entanglements as complementary crosslinks. By embodying properties of rapid stress relaxation, softness, ionic conductivity, self-healability, flaw-insensitivity, self-adhesion, and water-resistance, this ionic skin fosters excellent interfacial compliance with cyclically deforming substrates, and facilitates the acquisition of high-fidelity electrophysiological signals with alleviated motion artifacts. The presented strategy is generalizable and could expand the applicability of epidermal ionic skins to more complex service conditions.

It is a great challenge to regulate the mechanical properties precisely with both softness and toughness so as to match the requirements of various flexible device applications. Inspired by the three-dimensional network of collagen in connective tissues, a novel biopolymer poly(caprolactone-co-urethane) with hierarchical cross-links was synthesized on the basis of polycaprolactone (PCL) and composite chain extenders of tannic acid (TA) and 1,4-butanediol (BDO). The biopolymer P(CL-TAx/BDOy) possesses both physical and chemical cross-links in coordination with phase separation microstructure, sensitive to the molar ratio of TA/BDO. The optimal P(CL-TA1/BDO1) shows connective tissue-like properties, possesses an initial modulus less than 0.5 MPa but high toughness (61.2 MJ m–3), unique adhesive property, and shape memory behavior. A flexible actuator was prepared by P(CL-TA1/BDO1), exhibiting the shape transformation behavior by an electricity stimulation. This work provides a novel facile method to design biopolymers, including tuning the mechanical properties and integrating multifunctions through the hierarchical cross-link strategy.

The present zwitterionic hydrogel-based wearable sensor exhibits various limitations, such as limited degradation capacity, unavoidable toxicity resulting from initiators, and poor mechanical properties that cannot satisfy practical demands. Herein, we present an initiator and crosslinker-free approach to prepare polyethylene glycol (PEG)@poly[2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) (PSBMA) interpenetrating polymer network (IPN) hydrogels that are self-polymerized via sunlight-induced and non-covalent crosslinking through electrostatic interaction and hydrogen bonding among polymer chains. The PEG@PSBMA IPN hydrogel possesses tissue-like softness, superior stretchability (∼2344.6% elongation), enhanced fracture strength (∼39.5 kPa), excellent biocompatibility, antibacterial property, reliable adhesion, and ionic conductivity. Furthermore, the sensor based on the IPN hydrogel demonstrates good sensitivity and cyclic stability, enabling effective real-time monitoring of human body activities. Moreover, it is worth noting that the excellent degradability in the saline solution within 8 h makes the prepared hydrogel-based wearable sensor free from the electronic device contamination. We believe that the proposed strategy for preparing physical zwitterionic hydrogels will pave the way for fabricating eco-friendly wearable devices.
