“…The TA@HC has an average size of 300–400 nm (Figure S1), which is larger than the size of HC (Figure S2). The Fourier transform infrared of TA@HC has an obvious absorption peak (813 and 1600 cm –1 ) of the characteristic aromatic structure (Figure S3), which indicates that HC was successfully modified by TA . After the addition of Fe 3+ , the color of the solution was brown to dark brown (Figure S3).…”

“…Biomass-based materials have been extensively studied in the preparation of hydrogels due to their wide range of sources: cost effectiveness and cellular compatibility are among some of the other advantages. − The performance of hydrogels can be improved by using fillers. − In fact, there have been many studies using cellulose nanocrystals and their derivatives, − lignin nanoparticles, and their derivatives for enhancing the mechanical properties and/or other functionalities of the resultant hydrogels, , particularly, for applications as strain sensors. For example, PAA hydrogels filled with PEDOT/lignin reaches a tensile strain of 1350% .…”

“…27 However, hemicellulose, another important plant-derived natural polymer, 28 has not often been studied as an environmentally friendly functional filler for hydrogel preparation. 29 Recently, Gong et al 21 reported the preparation of ionic hydrogels in a two-step process consisting of (1) free radical polymerization of acrylic acid (AA), using APS as the initiator and MBA as the chemical crosslinker, in the presence of hemicellulose nanoparticles and (2) immersion of the resultant hydrogel in a 0.1 mol/L Al 3+ solution for 2 h, as well as their applications as strain sensors. However, this hydrogel-forming reaction was slow, and the mechanical properties of the hydrogels were inferior.…”

Smart functional fillers can significantly enhance the comprehensive properties of ionic hydrogels, such as their mechanical properties, which are key features of hydrogels in wearable sensor applications. As a plant-derived natural polymer, hemicellulose can serve as smart functional fillers. In this study, tannic acid-modified hemicellulose nanoparticles (TA@HC) and Fe3+ were used in the preparation of PAA/TA@HC/Fe3+ hydrogels. The addition of TA@HC and Fe3+ in the sodium persulfate (SPS) and acrylic acid (AA) polymerization system resulted in a fast gelation process that was completed within a short time (as short as 30 s) at room temperature. The catechol-rich TA and Fe3+ system allows for quick activation of SPS to produce free radicals, generating abundant hydroxyl groups in a short period of time, which was responsible for the fast gelation. Furthermore, due to the TA@HC effect and the dynamic catechol (TA)-Fe3+ redox system, the PAA/TA@HC/Fe3+ hydrogel exhibited excellent mechanical properties with an exceptionally high strain (as high as 5600%), adhesiveness, rapid and efficient self-healing ability, and reproducible self-adhesion onto various substrates. More importantly, asymmetric adhesive PAA/TA@HC/Fe3+ hydrogels were prepared by selective Fe3+ coating of the upper hydrogel surface to render the top surface nonadhesive so that the same hydrogel with different adhesiveness between the upper and bottom surfaces was obtained. The asymmetric adhesive hydrogel design permits the adhesive side to fit comfortably to the skin and the nonadhesive side showing anti-interference against various different pollutant materials, accurately serving as a pressure sensor.

Early warning sensors rapidly monitor critical temperatures, humidity, and fires, which are crucial to reduce or avoid natural disasters in complex environments, such as fire or water disasters. Here, a highly sensitive, readable, and dual‐functional sensor is designed for a fast‐response fire alarm and rapid humidity detection based on sustainable biological films (named MSCG films). The MSCG films are composed of grafted sisal nanofibers (MgC), silk nanofibers, graphene, and citric acid (CA). After crosslinking with CA, MSCG films exhibit good wet strength (i.e., 128.8 MPa) after soaking in 100 °C water, thus confirming that the films would be applicable to a broad temperature range in humid environments. After flame ignition, the MSCG films are rapidly carbonized to activate an alarm sound and a light in the circuit with a fire response time as short as 1 s. It exhibits ultrafast temperature response/recovery time (i.e., 0.1 s/0.3 s) and rapid humidity response time (i.e., 0.9 s). The dual‐functional sensor is further assembled into a versatile sensor system for real‐time monitoring of fire accidents and environmental humidity, which can be integrated into consumer electronics, such as portable laptops and mobile phones.
