“…By combining molecular assembly and engineering manufacturing strategies, AgNWs and conductive polymers can be incorporated into cellulose materials to design conductive electrodes or dielectric layers to prepare flexible sensors. [28,88,132] For example, using an assembly/encapsulation integration strategy, Wang et al [28] fabricated a flexible, transparent, and stable-conductivity functional film (CRC-film), by combining cellulose with PEDOT:PSS to protect AgNWs from oxidizing and falling (Figure 8c). Due to the synergistic coordination complexation and hydrogen bonding of cellulose molecular chains and PEDOT:PSS molecules, the CRC-film with robust interfaces and structural stability exhibited stable conductivity, even when subjected to severe conditions, such as a relative humidity of 90% for 60 days (T = 65 °C), repeated large-scale bending for 500 cycles, and more than 400 peeling tests.…”

“…It could also detect different mechanical strain signals, such as pressing (distinguishing the magnitude of pressure), touching, bending, and breathing airflow (Figure 8d). [28] Tong et al [119] prepared a low-temperature resistant cellulosebased functional hydrogel by chemically cross-linking cellulose molecular chains in a NaOH/urea aqueous solution. The cellulose-based hydrogel showed high compressibility (compression strain reaching 80%), large stretchability (tensile strain up to 126%), high transparency (light transmittance of 89% at 550 nm), and high ion conductivity (0.16 mS cm −1 ), as shown in Figure 8e,f.…”

“…[4] Meanwhile, nanomaterials such as conductive polymer sheets, metal oxide nanoparticles, 2D covalent layers, and responsive polymer molecules, can be well-integrated with cellulose macromolecules during self-assembly processes to create functional materials with conductive, magnetic, electrochemical, and stimuli responsiveness. [28][29][30][31] These properties offer huge opportunities for creating cellulose materials, such as transparent substrates, flexible conductors, electronic-ionic gels, electrolytes, and dielectric layers, in flexible sensors, conductive transistors, supercapacitors, optoelectronic devices, and bioelectronics.

Structural design and self‐assembly at the molecular level provide feasible strategies for constructing materials with novel and unique properties. Cellulose is one of the most abundant bioresources and is renewable, biodegradable, biocompatible, and environmentally friendly. The formation of hydrogen‐bonding networks between the cellulose molecular chains on the one hand gives cellulose a rigid crystalline region and high mechanical strength and on the other hand it causes inconvenience to material design based on the molecular scale. The emergence of eco‐friendly solvents such as ionic liquids and alkali/urea solutions breaks the hydrogen bonds and allows the design of various cellulose‐based functional materials, such as membranes, gels, fibers, and nano/microspheres via structural optimization and molecular self‐assembly. Such functional materials have promising applications in flexible electronic devices, such as electrochemical energy storage devices, sensors, biomimetic electronic skins, and optoelectronic devices. In this review, green solvents for cellulose, the dissolution–recombination process, molecular self‐assembly strategies, advanced applications, and future development prospects for high‐performance cellulose‐based functional materials with unique structures are presented.

Wearable strain–humidity sensors are increasingly recognized for their role in healthcare and detecting human motion signals. However, many strain–humidity sensors require complex manufacturing processes and have limited applicability. In this study, based on the good miscibility between natural rubber latex (NRL) and poly (3,4‐ethylenedioxythiophene):poly (4‐styrenesulfonate) (PEDOT:PSS), PEDOT:PSS/NRL composite conductors are transferred onto fabric substrate through screen printing and prepared high‐performance strain–humidity sensor. The PEDOT:PSS/NRL blends strain–humidity sensor exhibited good stability and durability (500 cycles) at 10% strain, achieves a gauge factor (GF) of 123.8 with excellent linearity, making it operational in detecting various human motions, such as finger bending, elbow bending, wrist bending, and so on. In addition, the PEDOT:PSS and water molecules interaction results in a humidity response time as low as 0.72 s and recovery time as low as 0.85 s for the PEDOT:PSS/NRL composite strain–humidity sensor, and a wide relative humidity detection range (6–83%), allowing it to be utilized for precise detection of human breathing. Furthermore, it can monitor the use's joint movement, facial muscle movement, and respiratory rate, which show its potential application prospect in health monitoring.

Conductive hydrogels have been promising candidates for wearable and flexible electronics due to their high flexibility and biocompatibility. However, the previously reported hydrogels with conductivity over 1000 S m−1 usually have poor mechanical properties including low tensile stress (<5 MPa) and toughness (<2 MJ m−3). Here, a liquid metal‐doped polyvinyl alcohol (PVA‐LM) hydrogel is presented, which simultaneously combines ultra‐high conductivity (maximum of 217 895 S m−1) with excellent mechanical properties, including high tensile stress (15.44 MPa), large tensile strain (704%), high toughness (43.02 MJ m−3) and excellent fatigue resistance. Such extremely high conductivity is afforded by self‐sintering behavior of LM at the bottom surface that enables the formation of conductive networks. The formation of polymer crystalline regions and polymer‐tannic acid multiple hydrogen bonds are responsible for the impressive mechanical properties of conductive hydrogels. Particularly, the electric LM filler could be recycled in the robust hydrogel by dissociation of multiple dynamic interactions. Most importantly, wearable electrodes and capacitive sensors are developed utilizing PVA‐LM hydrogel. These devices enable accurate monitoring of bioelectrical signals and human motions, highlighting their immense potential in the realm of soft electronics and wearable technology.
