“…The CMPC film has much lower resistance (7.2 Ω/sq) in the presence of both MXene and PEDOT:PSS, which is much lower than other cellulose-based conductive materials 24 and even lower than conventional ITO conductive materials. 25 The high conductivity of CMPC film is attributed to the following factors: (1) Strong hydrogen bonding forms between CNF, MXene, and PEDOT:PSS, resulting in the formation of dense and continuous composite films, as discussed above.…”

Actuators have many applications in artificial muscles, soft robots, and optical switches. Herein, we designed and fabricated a multifunctional actuator using cellulose composites that can be driven by humidity, natural sunlight, and electrothermal processes. Highly conductive and flexible cellulose, MXene, and PEDOT:PSS composite (CMPC) films were prepared with a facile blendingvacuum filtration method. Benefiting from the high conductivity, the CMPC film exhibited excellent performance in electromagnetic shielding, electrothermal processes, and humidity detection. Moreover, due to the hygroscopic properties of cellulose, CMPC film shows a negative coefficient of thermal expansion, in contrast to typical polymer films. By depositing a hydrophobic polytetrafluoroethylene (PTFE) film onto the CMPC film, a two-layer actuator was developed. Owing to the opposite thermal expansion properties of CMPC and PTFE, the as-obtained actuators exhibit a high sensitivity, and are made into bionic flowers, worms, robots, and smart curtains, showing fast responses to humidity, natural sunlight, and electrothermal processes. In fact, natural sunlight of 80 mW cm −2 or a power supply of as low as 3 V can drive the actuator to a bending curvature of 2.85 cm −1 , corresponding to a bending angle of 360°. The bionic robot is configurable with movements and speeds that can be controlled by a microcontroller and have a wide application in biological bionic and soft robots.

“…The electrical resistances of PEDOT/RC-SPP were 5938.3 ± 1131.5, 1631.2 ± 425.2, and 960.3 ± 102.2 Ω/cm for tosylate contents of 20, 30, and 40 wt %, respectively, while those of PEDOT-RC-VPP were 612 ± 97.3, 441.2 ± 40.5, and 261.5 ± 17.3 Ω/cm (Figure C,F). These results indicated that the tosylate concentration, as both the oxidant and dopant, is an extremely important factor in determining the electrical properties of PEDOT/RC. , Importantly, PEDOT/RC-VPP exhibited a higher electrical conductivity than PEDOT/RC-SPP. For example, compared with PEDOT/RC-SPP (7.3 ± 0.8 and 11.6 ± 0.6 S/cm at 30 and 40 wt % tosylate, respectively), the electrical conductivity of PEDOT/RC-VPP was 172.6 ± 11.2 and 198.2 ± 7.3 S/cm at 30 and 40 wt % tosylate, respectively.…”

“…Recently, electronic waste (e-waste) has emerged as a serious contamination problem in the environment. − This is because of the rapid development in electronics technology, short lifetime of electronic devices, and high recycling cost. − Furthermore, discarded e-waste may lead to the release of large toxic elements, including heavy metals and hazardous chemicals, which could eventually enter the biological system via soil, water, and human food chains. , To address this problem of e-waste, a promising strategy is to develop “green” electronic devices based on biodegradable or renewable polymers. Interestingly, green flexible electronic devices, which comprise biodegradable celluloses, have garnered considerable attention for a variety of applications since cellulose is an abundant, low-cost, and sustainable material. − Many laboratories, including ours, have been dedicated to the development of various conductive composites based on cellulose for green electronics, to retain conductivity and introduce environmental friendliness and facile recycling/disposal. − …”

Green electronics based on biodegradable polymers have received considerable attention as a solution to electronic waste (e-waste). Herein, we describe an efficient approach to constructing green conductive fibers, comprising poly(3,4-ethylenedioxythiophene) (PEDOT) and regenerated cellulose (RC), via a wet-spinning process and vapor-phase polymerization (VPP). Eco-friendly RC fibers were prepared as a support layer by wet spinning, and the conductive PEDOT layers were coated onto the surface of the RC fibers by the oxidation of EDOT monomers. We demonstrated that the vapor-phase-polymerized PEDOT/RC composite fibers (PEDOT/RC-VPP) exhibited approximately 17 times higher electrical conductivity (198.2 ± 7.3 S/cm), compared with that of the solution-phase-polymerized PEDOT/RC composite fibers (PEDOT/RC-SPP, 11.6 ± 0.6 S/cm). Importantly, PEDOT/RC-VPP exhibited a high tensile strength of 181 MPa, good flexibility, and long-standing electrical stability under ambient air conditions. Moreover, the obtained PEDOT/RC-VPP under 50% strain turned on a green light-emitting diode (LED), indicating the flexibility and stability of green conductive fibers. This strategy can be easily integrated into various electronic textiles for the development of next-generation wearable green electronics.

“…Direct cross-linking of conductive polymer chains is a straightforward and effective method for constructing conductive hydrogel networks (Figure 2A). For example, aniline, 34 pyridine 35 and 3,4-ethylene two oxygen thiophene 36 are well-known conductive monomers for fabricating conductive hydrogels. This strategy is widely used to prepare conductive hydrogels for flexible electronics applications.…”

Flexible sensors have great potential in the application of wearable and implantable devices, and conductive hydrogels have been widely used in wearable sensing devices due to their biomimetic structure, biocompatibility, adjustable transparency and stimuli-responsive electrical properties. Conventional conductive hydrogels are prone to be damaged in their application process and lack of long-term reliability. Inspired by natural organisms such as mussels, introduction of self-healing capabilities has been regarded as a promising approach to extend the service life of hydrogel sensing devices. This work
