Conductive hydrogels show great potential for flexible sensors, yet their applications are limited by low strength, poor freeze resistance, and easy dehydration. To address these issues, this paper developed a multifunctional PVA (polyvinyl alcohol)/CMC (carboxymethyl cellulose sodium)/PANI (polyaniline)/PA (phytic acid)/BA (boric acid)/Fe 3+ hydrogel (denoted as PMNF) with a double-network structure formed via the Hofmeister effect and in situ polymerization. The hydrogel exhibits excellent mechanical properties (tensile strength: 236 kPa; elongation: 541%), high conductivity (2 S/m), and improved antifreezing behavior. At −12°C, it retains a conductivity of 0.86 S/m and over 300% elongation. It also demonstrates strong water retention after 15 days and stability in acidic/alkaline salt environments. Based on these properties, PMNF-based sensors reliably detect both subtle and large human motions under various conditions. This work offers a practical strategy for developing robust wearable electronics suited for real-world use.

Polyaniline (abbreviated as PANI), a promising electrochromic material, exhibits broad optical tunability and rapid switching time. However, the prolonged preservation of its leucoemeraldine state is hindered by the high thermodynamic stability of its emeraldine salt state. In this work, density functional theory calculation reveals that titanium oxide doping substantially elevates both the highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels in oxidized PANI-TiO2 composites, facilitating electron excitation and polaron formation. Coupled with expanded electrochemical active surface areas and enhanced ion transport efficiency, the synthesized PANI-TiO2 composite films achieve an optical contrast of 73.8%. The coloration and bleaching time of PANI-TiO2 composites was determined to be 0.46 and 0.94 s, respectively, significantly surpassing those of pure PANI films. Moreover, the composites demonstrate exceptional infrared modulation capabilities, exhibiting an emissivity variation (Δε) of 0.61 under low-voltage stimuli (≤1 V). These findings provide a fundamental insight into the structural engineering strategies for advanced electrochromic materials.

In this work, we synthesized a core-shell conductive filler of carbon nanotubes covered with polyaniline (PANi@CNTs), which showed good dispersibility to prepare highly flexible and foldable dielectric PMCs (PANi@CNTs/PU). The dielectric, mechanical, and thermal properties of the PANi@CNTs/PU composites were investigated. The mechanical flexible and foldable PANi@CNTs/PU composites could be promising dielectric material for preparing thin film capacitors.

Black phosphorus (BP) has a high theoretical capacity of 2596 mA h g–1, which is promising for applications of lithium-ion batteries. However, during the process of charging and discharging, the extraction/insertion of lithium ions occurs, which causes severe volume expansion of the BP anode material, resulting in the collapse of the active material structure and a decline in the lithium storage performance of the material. It is still challenging to construct stable structures in the outer layer of BP materials to improve electrochemical performance. Here, we report a structurally stable BP-based composite by combining the ball milling method and in situ polymerization to improve the structural stability and electrochemical properties of the material. The initial discharge specific capacity of the PANI/(BP–CNT) composite is 2127.9 mA h g–1, and the reversible capacity is 1150.7 mA h g–1 after 100 cycles. In addition, the mechanism responsible for the stable structure of the composite materials is discussed. The PANI in the composite has a swelling property that can greatly improve the stability of the material, and the CNT protects the edge structure of the BP from collapsing and improves the electrical conductivity of the material. This work provides an experimental design concept for the application of BP-based energy materials.

Solar-powered interfacial evaporation technology is seen as a potential way to alleviate the crisis of water scarcity through seawater desalination. The key to the success of this technology hinges upon the efficient conversion of solar energy into heat energy, which is intimately connected with the innovative development of composite photothermal membranes. In this study, polyaniline (PANI) with excellent light absorption and carbon black (CB) with good stability were added to the polymer material polyaryl ether nitrile (PEN), and the PANI/CB-PEN nanofiber membrane was prepared by electrospinning blending. Due to the good stability of PEN polymer, the solar evaporator has excellent salt resistance and stability. The results show that the fiber membrane has the best light absorption effect when the reaction time is 80 min and the CB content is 50.0%. The composite fiber membrane temperature can reach 68.6°C, the evaporation rate is 1.51 kg m −2 h −1 , while the evaporation rate is 1.38 kg m −2 h −1 in a 3.5% NaCl brine. The photothermal conversion efficiency was 94.17%. The PANI/CB-PEN nanofiber membrane-based interfacial evaporation device demonstrates sustained performance in repeated tests, showing promising potential for long-term, scalable solar-powered seawater desalination applications.

Water evaporation using photothermal materials is a cost-effective and sustainable technology for alleviating the world’s freshwater crisis, but oil contaminants and organic pollutants exist in the original water sources, which severely degrade the evaporation performance and pose environmental hazards. In this paper, we demonstrate a photothermal material (multifunctional cotton) that simultaneously demonstrates oil-resistance, organic pollutant removal, and a high water evaporation rate. A Schottky heterostructure was formed between polyaniline (PANI) and Ag NPs, which improved the photothermal conversion and achieved a water evaporation rate of 1.37 kg m −2 h −1 and photothermal conversion efficiency of 84.7% under one-sun illumination (1 kW m −2 ). Notably, various organic pollutants in the water source were thoroughly removed by visible-light catalytic degradation and adsorption, which displayed efficiencies of 99.3% and 97%, respectively. The multifunctional cotton also possessed excellent superoleophobicity, and repelled oil contaminants and organic pollutants in water. Considering these merits, the as-prepared multifunctional cotton is an outstanding candidate for water evaporation from various sources.

The polyaniline (PANI)/TiO2 nanocomposites have been successfully synthesized via a hydrothermal method and followed by a low-temperature calcination treatment process. We find that such a PANI/TiO2 nanocomposite exhibits higher photocatalytic activity and stability than bare TiO2 and TiO2-xNx toward the liquid-phase degradation of methyl orange (MO) under both UV and visible light (420 nm < λ < 800 nm) irradiation. More noteworthy, the PANI/TiO2 photocatalyst still perform good activity toward MO and 4-chlorophenol (4-CP) under the longer wavelength of light (550 nm < λ < 800 nm). The total organic carbon (TOC) tests show that the mineralization rate of MO and 4-CP over PANI/TiO2 are apparently higher than bare TiO2 under the irradiation of both UV and visible light. The presence of synergic effect between PANI and TiO2 is believed to play an essential role in affecting the photoreactivity. At last, the roles of active species in the photocatalytic process are compared by using different types of active species scavengers. Meanwhile, the degradation mechanism of the photocatalysts is proposed. It is hoped that our work could provide valuable information on the design of polymer modified semiconductor with more excellent properties and set the foundation for the further industrial application.

MXene is considered a promising two-dimensional (2D) material with excellent conductivity, and it has been proved to be a potential material for supercapacitor electrode. However, the supercapacitive performances of the pristine MXene are always not satisfactory due to the innate re-stacking tendency of the MXene nanosheets . In this work, the carbon nanotubes/polyaniline (CNT/PANI) nanocomposite was introduced and obtained MXene-CNT/PANI ternary composite electrode. Thanks to the synergy between each component, MXene-CNT/PANI exhibited enhanced specific capacitance that reached 429.4 F/g at 1A/g, which is completely better than that of any single compound in the ternary material. Besides, this ternary composite electrode holds a high stable cycle performance with over 93% retention after 10,000 cycles. Furthermore, a quantitative analysis was also carried out to prove the relationship between the capacitive contribution and the scan rate of the MXene-CNT/PANI.

MXene , as a new 2-dimensional (2D) material, has excellently potential applications in the field of electrochemistry owing to its high conductivity and fast charge transporting speed. Especially, MXene/polymer composites have attracted widely attentions due to their extensive application in the area of multi-functional materials. Herein, the composites of Ti 3 C 2 T x MXene/polyaniline (PANI) with different PANI contents have been successfully prepared. The microwave absorption mechanism of these materials was investigated. Attributing to the multiple layer structure, the dielectric property of Ti 3 C 2 T x MXene and PANI, and the synergistic effect between the Ti 3 C 2 T x and PANI, the as-prepared composites possessed a specific microwave absorbing behavior. With a proper content of PANI, the MXene/PANI composites in a paraffin matrix exhibited a maximum reflection loss of −56.30 dB at 13.80 GHz with the thickness of 1.8 mm. In addition, the effective absorption bandwidth (>90%) ranged from X-band (8–12.4 GHz) to Ku-band (12.4–18 GHz) with the tunable thickness ranging from 1.5 to 2.6 mm. The results indicate that MXene/PANI composites has great potential to be used in the field of microwave absorption.

A ternary graphene/Au/PANI nanocomposite (GAP) is designed and fabricated via a facile two-step approach: Au nanoparticles dispersed on graphene sheets are achieved by a hydrothermal method, followed by coating with PANI through an in situ polymerization process. Electrochemical measurements demonstrate that the specific capacitance of the resulting ternary composite is 572 F g−1 at a current density of 0.1 A g−1 using a three-electrode system, which is significantly higher than that of pure PANI and the binary graphene-PANI composite. In addition, over 88.54% of the initial capacitance can be retained after repeating tests for 10 000 cycles, demonstrating a high cycling stability. The extraordinary electrochemical performance of the ternary GAP nanocomposite is attributed to its well-designed nanostructure and the synergistic effects among individual components.

Using hierarchical hollow MoS 2 microspheres constructed by ultrathin nanosheets as a framework to provide large active surface area, polyaniline (PANI) nanofibers are controllably assembled on their surfaces by in-situ oxidative polymerization of different amounts of aniline monomers. The morphology and structure of these resulting composites are characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) spectroscopy analyses. In order to assess the electrochemical performances of the composites, cyclic voltammograms (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charging-discharging (GCD) tests are employed. The as-prepared MoS 2 /PANI-5 composite electrode delivers an enhanced specific capacitance about 633 F g −1 at the current density of 0.5 A g −1 , as well as shows a remarkable capacitance retention of 86.0% at 10 A g −1 after 1000 cycles. In addition, the energy density reaches to 31.7 W h kg −1 when the power density is 0.3 kW kg −1 . All the electrochemical tests indicate this composite has an application prospect as an electrode material for supercapacitors.

Incautious discharge of organic dyes such as methyl orange (MO) has produced serious pollution to the environment, calling for the efficient techniques to remove them with retaining the green world. The photo-catalytic degradation of organic dyes is promising among the developed techniques. Thus, a strategy based on transpiration-prompted photocatalytic degradation of dye pollutant under sunlight is put forward. Aniline (ANI) is graft-polymerized onto poly(acrylamide- co-N -4-aminophenylacrylamide) (PAAm) cryogel embedded with gold nanoparticles (AuNPs, diameter: 4–10 nm). The obtained cryogels integrated with AuNPs and PANI inside PAAm matrix (AuNP@PAAm- g -PANI) have been structurally explored based on the chemical composition and the phase/porous morphology. SEM and TEM observation shows that PANI and AuNPs are uniformly distributed in PAAm matrix. Since the macro-porosity of cryogel, hydrophilicity of PAAm and photo-thermal activity of PANI, PAAm-g-PANI cryogels without AuNPs can have a photo-thermal evaporation rate of water at 1.63 kg·m −2 ·h −1 . As a comparison, AuNP@PAAm- g -PANI cryogels with AuNPs exhibit higher one at 2.20 kg·m −2 ·h −1 , suggesting the promotion of AuNPs to photo-thermal evaporation. Meanwhile, PANI appreciatively assists AuNPs to display higher catalytic ability for the oxidative degradation of MO. Therefore, the removal of MO from water is obviously prompted by the water transpiration under sunlight with AuNP@PAAm- g -PANI cryogels, whose rate constant can reach to 0.320 h −1 , being three folds of that for the sole absorption of MO. This transpiration-prompted photocatalytic degradation provides a fascinating route to eliminate organic pollutants and obtain pure water from wastewater simultaneously with sustainable sunlight energy.
