Underwater sensors play a crucial role in marine exploration, resource development, environmental monitoring, and national defense security. Gel sensors, with their flexibility, biomimetic properties, and environmental friendliness, are indispensable in marine precision detection and biointeraction scenarios. However, the tendency of hydrogels to swell and leak ions in aquatic environments limits their application in underwater sensing. Against this backdrop, this paper proposes a gel preparation strategy that induces hydrophobic chain aggregation to achieve gel swelling resistance, followed by in situ growth of conductive polymers on the gel surface to achieve high-sensitivity response. The prepared gel sensor exhibits excellent swelling resistance (swelling rate of 5.73%), good mechanical properties (tensile strain of 1484.81%), and high sensitivity (GF = 3.21). As a multifunctional gel sensor suitable for both aquatic and terrestrial environments, it also exhibits an ultrawide operating range and linearity (0 to 500% strain range) to ensure reliable detection under high-strain conditions. Additionally, it exhibits excellent fatigue resistance (1000 cycles at 70% strain) and rapid response/recovery times (0.43 s/0.36 s in tensile state and 0.34 s/0.41 s in compressive state). Therefore, with these outstanding performance characteristics, the designed multifunctional gel sensor, when combined with deep learning algorithms, can not only be used for human motion detection, information encryption transmission, and speed recognition scenarios, but also can be used underwater to construct an independent detection system that integrates data sensing, collection, and transmission to achieve human motion perception. Consequently, the designed amphibious gel sensor not only enables daily human motion monitoring but also has significant application value in underwater rescue and marine ecological monitoring.

With the development of 5G communication technology, electronic devices face the challenge of performance fluctuations when exposed to temperature-varying environments and multiband electromagnetic radiation. Addressing the limited performance of single-component materials, this article proposes a design strategy for synergistically enhanced composite films. Through the synergistic effects of multiple components and the regulation of multidimensional structures, the performance limitations of functional materials are overcome. In this work, a hierarchical aramid nanofiber (ANF)/silver nanowire (AgNWs)/multiwalled carbon nanotube (MWCNTs)-poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) composite film was fabricated via stepwise vacuum filtration. The bottom-layer ANF provides robust mechanical stability, and AgNWs in the interlayer form the primary conductive network. The top-layer MWCNTs-PEDOT:PSS with a “reinforced-concrete” structure significantly enhances the interfacial adhesion between AgNWs and ANF layers. This architecture fills conductive network gaps, creates additional pathways, and retards AgNWs’ oxidation effectively. The composite film retains excellent mechanical properties with a tensile strength of 231.67 MPa. It exhibits a rapid electrothermal response, reaching 122 °C from room temperature within 15 s under a low voltage of 4 V. Meanwhile, its electromagnetic interference (EMI) shielding effectiveness in the X-band reaches 35.57 dB. It overcomes the performance limitations caused by uneven dispersion of traditional fillers and poor interfacial adhesion. These advantages endow it with great potential in various fields, such as smart wearable devices, aerospace engineering, flexible electronics, and medical applications.

Solar cells formed by spin-coating organic absorber layers on silicon have attracted widespread attention due to their simple processes and high photovoltaic conversion efficiency (PCE). In typical organic/Si solar cells, however, surface defects or unsatisfactory carrier separation are inadequate to yield excellent device performance. Here, the Au@MoS 2 nanocomposites are well synthesized and doped into the organic layer of poly (3,4-ethylenedioxythiophene)/polystyrene sulfonate (PEDOT:PSS) to improve its work function and the performance of PEDOT:PSS/Si HSCs consequently. By optimizing the doping level of Au@MoS 2 , the PCE significantly improved from 11.48% to 14.0% by tuning the work function of the PEDOT:PSS layer to more appropriate values. The calculated results based on the Mott–Schottky model indicate that the built-in field in the PEDOT:PSS/Si interface of HSCs is significantly enhanced due to the increase of work function by the PEDOT:PSS thin films. The enhancement of the built-in field results in the reduction of the electron–hole recombination loss effectively. The work provides a feasible method for preparing high-performance PEDOT:PSS/Si HSCs.

Living organisms in nature can sensitively perceive environmental stimuli and respond through rapid adaptive deformation. Inspired by this functionality, self-sensing hydrogel actuators have been developed, offering broad potential in areas such as information encryption, flexible wearables, and human–machine interfaces. Here, we report a versatile strategy for fabricating self-sensing hydrogel actuators with simultaneously high electrical conductivity and excellent mechanical durability. A robust interpenetrating network is constructed between surface-functionalized MXene nanomonomers (T-MXene) and modified cellulose nanocrystals (CNC-Vi), which markedly enhances the stability of poly(N-isopropylacrylamide) (PNIPAm) hydrogel. In addition, incorporation of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) further enhances the composite’s electrical conductivity while simultaneously improving the environmental adaptability. The resulting hydrogel exhibits high conductivity (14.92 S m–1), remarkable strain sensitivity (GF of 2.17 to 7.23), and outstanding durability. Leveraging these features, we realize reliable information encryption and storage, as well as wearable motion sensors capable of sensitive and precise motion detection. Moreover, the hydrogel system serves as an excellent platform for constructing high-performance self-sensing actuators. By inducing a gradient alignment of T-MXene/CNC-Vi under a direct-current (DC) electric field, we develop a shape-programmable hydrogel actuator that combines rapid responsiveness, remote light-driven actuation, and intrinsic self-sensing capability. This study not only provides a paradigm for designing advanced tactile and self-sensing materials but also establishes a foundation for achieving closed-loop, remotely controlled soft actuators for next-generation intelligent mechanical systems.

With the rapid development of intelligent, portable, and wearable electronic devices, flexible electromagnetic interference (EMI) shielding materials with integrated multifunctional performance have gained increasing attention. In this work, the flexible sandwich-structured aramid nanofiber (ANF)/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS)-MXene-ANF/PEDOT:PSS composite film was successfully fabricated through alternating vacuum-assisted filtration and laminated hot pressing. Within this system, PEDOT:PSS played a dual role in enhancing interfacial bonding and regulating electrical conductivity. As an interfacial binder, PEDOT:PSS significantly strengthened the adhesion between the MXene layer and the ANF substrate through strong interfacial interactions. Meanwhile, as a conductive bridge, its conjugated π-π structure facilitated efficient electron transport and carrier migration, markedly improving the overall conductivity of the film. The synergistic interaction between PEDOT:PSS and MXene led to the formation of a continuous and stable conductive network, providing efficient pathways for charge transport and energy dissipation. As a result of this synergistic design, when the mass ratio of PEDOT:PSS to MXene was 1:6, the APM6 composite film exhibited optimal comprehensive performance, with an EMI shielding efficiency (SE) of 52.57 dB, a specific EMI SE of SSE/t of 7904.197 dB·cm 2 ·g −1 , a Joule heating temperature of 110℃ at 2.5 V, a photothermal conversion temperature of 185℃ under 0.6 W/cm 2 laser irradiation, and a tensile strength of 42.75 MPa. These results demonstrated that the composite film possessed excellent EMI shielding and thermal management capabilities, making it a promising candidate for advanced electronic devices, military and aerospace applications.

Stretchable electromagnetic shields have garnered significant attention in the burgeoning field of flexible devices, while traditional strategies developed to maintain adequate electromagnetic shielding performance under large strains are more challenging at low temperatures. Herein, elastic electromagnetic shielding films with segregated conductive network were produced by an extremely simple method of evaporating carboxylated nitrile butadiene rubber latex containing lithium bis(trifloromethanesulfonyl)imide doped poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate). The films of 0.2 mm in thickness are highly stretchable at −20 °C and exhibit an electromagnetic interference shielding efficiency of more than 30 dB at 100 % strain and −10 °C. These properties underscore the potential of the films as effective stretchable EMI shields in low-temperature conditions. Experiments demonstrating the films' ability to block Bluetooth signals from ESP32 chip microcontrollers and electromagnetic waves from Tesla coils further confirm their usefulness, highlighting the practicality of protecting flexible devices in cold environments.

We studied a Surface-enhanced Raman scattering (SERs) film by self-assembled deposition of Ag nanoparticles on the surface of PPy@PEDOT:PSS films to detect melamine molecules. The PPy@PEDOT:PSS film was prepared using an electrochemical polymerization method in a mixture solution of PPy and PEDOT:PSS. Then, Ag nanoparticles were directly deposited on the surface of PPy@PEDOT:PSS films by a chemical self-assembly method as an active SERs substrate to detect melamine molecules. The results showed that the density of Ag nanoparticles on the surface of PPy@PEDOT:PSS film was gradually increased due to the increase of depositional time of Ag nanoparticles. Accordingly, The SERs effect was also substantially enhanced. The signal of melamine was increased up to 440 times. The melamine molecules at 6.4 ng/ml concentration could be clearly identified. This preparing method of SERs film and detecting method of melamine molecules provide a new strategy for the design and application of chemical sensors and bio-sensors.

Inverted Perovskite Solar Cells (PSCs) with Poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT:PSS) as hole transport layer on account of its low-temperature solution processability, good flexibility and good film forming ability. Bis(acetylacetonato)dioxomolybdenum(VI) [CH 3 COCH = (O-)CH 3 ] 2 MoO 2 (BADM) as an effective dopant has been introduced into PEDOT:PSS for planar PSCs. The results show that the power conversion efficiency (PCE) is increased from 14.26% to 17.11% by using BADM to modify PEDOT:PSS, which is mainly due to the increase of filling factor and short circuit current density. Not only that, BADM doping can also improve the extensibility of perovskite film, which can be reflected on flexible substrate, when slightly bending, there are almost no cracks.

In this work, TiO2-MXene/poly (3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) composite was utilized as an electrode material for the sensitive electrochemical detection of baicalein. The in-situ growth of TiO2nanoparticles on the surface of MXene nanosheets can effectively prevent their aggregation, thus presenting a significantly large specific surface area and abundant active sites. However, the partial oxidation of MXene after calcination could reduce its conductivity. To address this issue, herein, PEDOT:PSS films were introduced to disperse the TiO2-MXene materials. The uniform and dense films of PEDOT:PSS not only improved the conductivity and dispersion of TiO2-MXene but also enhanced its stability and electrocatalytic activity. With the advantages of a composite material, TiO2-MXene/PEDOT:PSS as an electrode material demonstrated excellent electrochemical sensing ability for baicalein determination, with a wide linear response ranging from 0.007 to 10.0 μM and a lower limit of detection of 2.33 nM. Furthermore, the prepared sensor displayed good repeatability, reproducibility, stability and selectivity, and presented satisfactory results for the determination of baicalein in human urine sample analysis.Keywords:TiO2-MXene;oxygen vacancy;PEDOT:PSS;baicalein;electrochemical sensor

Due to the component advantages and structural features, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) based inorganic–organic composite films shows huge application potential in various fields. However, there are few reports on the bi-functions of thermoelectric (TE) and electromagnetic interference (EMI) shielding for the PEDOT:PSS-based functional films. Herein, metal–organic frameworks (MOFs)-derived Bi x Se y @C sheets with average size about ∼ 7.32 μm are obtained via the solvothermal reaction and selenization pyrolysis treatment, and then flexible free-standing Bi x Se y @C/PEDOT: PSS (BSCP) composite films are obtained by a feasible vacuum filtration combined with cold pressing treatment, using different contents of Bi x Se y @C content as inorganic component. Micrometer Bi x Se y @C sheets are uniformly dispersed in the PEDOT:PSS matrix constructing bi-functional composite films with unique layered structure. When the MOFs-derived Bi x Se y @C content is 70%, BSCP-70 composite film gets a power factor of 11.23 μW m −1 K −2 at 340 K. Meanwhile, the BSCP-70 composite film reaches the highest average total EMI shielding effectiveness (SE T ) value of 45.0 dB at only 41.9 μm thickness at X-band. Based on multi-physical properties of MOF-derived Bi x Se y @C and PEDOT:PSS, flexible Bi x Se y @C/PEDOT:PSS composite films display good application potentiality in the flexible TE devices and EMI shielding protection.

Skin-like pressure- and temperature-sensing capabilities are two important indicators for artificial human skins and flexible wearable sensors . However, artifact interference between measured signals has always been the technical difficulty in realizing multi-parameter real-time and highly sensitive monitoring. Herein, a stretchable and flexible pressure-temperature sensitive device based on 3D tubular graphene sponge/PEDOT:PSS composite is designed and fabricated. The hybrid Ag NWs/CNTs composite based embedded stretchable electrodes is selected as the signal transmission lines, which had the ability to resist tensile strain failure. The pressure-resistance module and the temperature-voltage module exhibits distinguishable features of detecting pressure and temperature stimulus simultaneously. The detection sensitivity of pressure and temperature stimuli is 43 kPa −1 and 24.5 μV/K, respectively. Moreover, a 3 × 3 sensor array is demonstrated to verify its monitoring effects in static and dynamic surroundings, illustrating its promising applications, such as health monitoring components, biomimetic soft wearable devices and human-machine interaction.

Conductive cotton fabrics are widely used in electromagnetic shields and soft sensors because of their excellent softness and comfort. Generally, conductive cotton fabrics are prepared by depositing an inorganic conductive coating or an organic conductive polymer coating on them. However, due to the complex structure of cotton fabrics, these conductive coatings easily fall off and fracture under external forces, resulting in a sharp decline in the conductive properties of the finished fabrics. In the present work, L-cysteine was used as a binder to immobilize Ag NPs on cotton fabric. Ag NPs were covered by PEDOT:PSS to prevent them from falling off and cracking. As a result, the surface resistance of finished fabric was arrived at 8.7 Ω/sq. The finished fabric also exhibited excellent electromagnetic shielding effectiveness, with an electromagnetic shielding reached at 27.1 dB. Moreover, the composite coating significantly improved the durability of electrical conductivity and electromagnetic shielding properties of the finished fabric. In addition, mist polymerization was used to retain the inherent properties of the cotton fabric. We believe that the proposed method provides a new direction for the preparation of conductive cotton fabrics with a high stability.
