The microstructure of photothermal materials plays a central role in interfacial solar evaporation, which is vital to solar absorption, thermal management, water and vapor transportation. Ordered structures constructed on cross-scale in a controllable fashion are potentially important for high-performance photothermic vaporization, and may provide fundamental insight into the correlation between microstructure and evaporation efficiency. Herein, the ordered photothermal materials featuring brilliant structural colors and spectral and thermal management are cross-scale assembled using unique colloidal photonic crystals (PCs) as the building block. Multidimensional ordered PC photothermal materials including PC layered nanofilms, microbeads and three-dimensional (3D) scaffolds are facially constructed by Langmuir-Blodgett, microfluidics and 3D printing techniques, respectively, exhibiting excellent internal light reflection and water wettability. As a result, the corresponding solar vaporization rates of 2.23, 2.14 and 2.0 kg m -2 h −1 are achieved under 1 sun, greatly surpassing that in disordered PC films. Notably, the structural color originated from periodic-arranged PC structure shows a regulable and colorful appearance, in contrast to the monotonous black color in conventional broadband photothermal materials. The controllable methodology for ordered architecture construction inspires more novel nanostructured and multifunctional photothermal materials for solar evaporation materials.

Flexible supercapacitors are an important portable energy storage but suffer from low capacitance, inability to stretch, etc. Therefore, flexible supercapacitors must achieve higher capacitance, energy density, and mechanical robustness to expand the applications. Herein, a hydrogel electrode with excellent mechanical strength was created by simulating the collagen fiber network and proteoglycan in cartilage using silk nanofiber (SNF) network and polyvinyl alcohol (PVA). The Young's modulus and breaking strength of the hydrogel electrode increased by 205 % and 91 % compared with PVA hydrogel owing to the enhanced effect of the bionic structure, respectively, which are 1.22 MPa and 1.3 MPa. The fracture energy and fatigue threshold reached 1813.5 J/m 2 and 1585.2 J/m 2 , respectively. The SNF network effectively connected carbon nanotubes (CNTs) and polypyrrole (PPy) in series, affording a capacitance of 13.62 F/cm 2 and energy density of 1.2098 mWh/cm 2 . This capacitance is the highest among currently reported PVA hydrogel capacitors, which can maintain >95.2 % after 3000 charge–discharge cycles. This capacitance Notably, the cartilage-like structure endowed the supercapacitor with high resilience; thus, the capacitance remained >92.1 % under 150 % deformation and >93.35 % after repeated stretching (3000 times), which was far superior to that of other PVA-based supercapacitors. Overall, this effective bionic strategy can endow supercapacitors with ultrahigh capacitance and effectively ensure the mechanical reliability of flexible supercapacitors, which will help expand the applications of supercapacitors.

Flexible fabrics have gained widespread attention in thermal management and energy harvesting recently due to their fascinating merits of flexibility and breathability. However, the simple and efficient integration of multiple functions into a single fabric remains a challenge. Herein, a multifunctional fabric was prepared by in-situ polymerized polyaniline (PANI) and polypyrrole (PPy) onto air-laid paper (AP), followed by wrapping with hydrophobic reagent. The synergistic effect of PANI and PPy networks endowed the composite fabric with excellent photothermal performance. Additionally, the smart fabrics exhibited the terrific self-cleaning property. More promisingly, triboelectric nanogenerator (TENG) based on the smart fabrics as effective positive friction material could transform electrical signal with through collecting energy from small human movement, delivering charge of 82.7 nC, open circuit voltage of 213.6 V, and short circuit current of 14.7 μA. This work provides new insights for the study of the next generation lightweight, portable thermal management fabric.

While asymmetric supercapacitors (ASCs) have huge potential as efficient, durable, and cost-effective energy storage devices, they fail to meet expectations because of the unoptimized architecture and composition of their electrode materials. Herein, PPy/PANI@MoS2 (PPMS) ternary composites with a dual-channel structure are obtained by facile hydrothermal and in situ polymerization methods. These dual conductive channels synergistically improve the electrode’s electrical conductivity, facilitate ion diffusion, enlarge the interlayer distance, and increase the accessible surface area. Taking advantage of such a favorable architecture, PPMS composites exhibit outstanding electrochemical properties, including a huge specific capacitance (1171 F g–1 at 1 A g–1) and rate capability (861 F g–1 at 20 A g–1) in three-electrode systems. Based on charge storage mechanism analyses, we demonstrate that the kinetic behavior of PPMS electrodes is dominated by the surface capacitance (95.9% at 100 mV s–1). Besides, PPMS-based ASCs (PPMS//activated carbon) operate in a broad voltage window (1.8 V), delivering an ultrahigh energy density of 93.4 Wh kg–1 at a power density of 884.8 W kg–1. They also show a superior cycling stability of 90.4% and a remarkable Coulombic efficiency of 99.2% for 10,000 cycles. This work affords an inspiration for rational structural optimization of PANI-based electrode materials with great prospects in the development of next-generation high energy density ASCs.

Smart electromagnetic (EM) functional materials that can arbitrarily utilize EM energy and reduce EM pollution are attractive for future EM devices in an information society; however, studies on precise EM interference (EMI) shielding and sensing are rare. In this work, dual-action electrical and EM-responsive mechanoreceptors are prepared from electrically conductive polypyrrole (PPy) nanoparticle (NP)-infiltrated anisotropic wood (PW) aerogels. The prepared PW aerogels are composed of curved stacked layers of aligned cellulose nanofibers, and can be reversibly condensed and reconstructed for conductive network control during cyclic compression. These PW aerogels can withstand up to 74% compressive strain in a tangential direction and exhibit pressing-enhanced electrical conductivity and polarization loss. The piezoresistive gauge factor (GF) and linearity of the PW aerogels can be adjusted by varying the PPy deposition time, leading to varying GF values in the range of 1.87–4.62. During mechanosensing based on EMI shielding effectiveness (SE), rapid off/on switching between the EM wave transmission and shielding is achieved when the SE varies above and below the effective EMI shielding area (>20 dB) through continuous compression. Such dual-action electrical/EM off/on wood aerogel switches provide opportunities for the development of advanced smart devices from biomass resources.

Assembling a heterojunction-based composite nanomaterial to simultaneously achieve higher response and superior selectivity towards NO 2 under room-temperature conditions remains a great challenge. In this work, the MXene@Polypyrrole heterojunction was synthesized via a facile in-suit chemical polymerization approach. The distribution of sphere-like PPy nanoparticles was confirmed via various characterization techniques. The response value of the 0.5MXP sensor toward 50 ppm NO 2 is significantly higher than that of the pristine MXene based sensor, entailing greater response (6.5-fold). Nearly 98.11% recovery to the base resistance was observed in each sensing cycle. Noteworthy, the Schottky barriers formed between MXene and PPy contact surface, leading to the ideal selectivity and a lower limit of detection. Additionally, the sensor was tested for a 31-days-period with minimal deviation, predicting outstanding reproducibility and durability. The detailed polypyrrole sensitization mechanism containing selectivity mechanism, underlying heterojunction mechanism as well as the Density Function Theory (DFT) calculation were also revealed, offering new ideas for the development of room-temperature nitrogen dioxide sensors. Simultaneously, DFT calculation (21 models, 42 images) revealed the adsorption energy, electron transfer , and charge density differences between the NO 2 molecules and the substrate (MXene, PPy and MXene@PPy). In summary, the outstanding MXene surface functionalization has been exploited by decorating with polypyrrole (PPy) nanoparticles.

Glucose is regarded as a clinical biomarker, and the abnormal level of glucose in blood would cause endocrine metabolic diseases. Thus, it is of great significance to develop a simple, accurate, and sensitive method for glucose detection. In this work, we synthesized an iron porphyrin-based porous organic framework (Fe-POF) through a facile alkylation reaction between 5,10,15,20-tetra(4-aminophenyl) porphyrin (TAPP) and cyanuric chloride. Fe-POF exhibited excellent peroxidase-like activity and could be used to detect hydrogen peroxide and the molecules associated with hydrogen peroxide such as glucose. The structure of Fe-POF was confirmed through a series of methods, such as FT-IR, SEM, EDS, TEM, and XPS. Fe-POF exhibited excellent peroxidase-like activity, which could catalyze the oxidization of colorless 3,3′,5,5′-tetramethylbenzidine (TMB) into blue product (ox-TMB) in the presence of hydrogen peroxide (H 2 O 2 ). Based on this phenomenon, a simple colorimetric assay was constructed for the detection of H 2 O 2 and glucose with high selectivity and sensitivity. The detection limit of H 2 O 2 and glucose was calculated to be 1.8 and 1.39 μM, respectively. Finally, Fe-POF was applied as a colorimetric sensor for rapid detection of glucose in diluted serum samples.

Polyzwitterionic hydrogel is an emerging material for solar-driven water evaporation in saline environment due to its special anti-polyelectrolyte effect, which is a promising approach to co-generation of freshwater and electricity. However, the molecular impact on anti-polyelectrolyte effect remains unclear, let alone to optimize the zwitterionic structure to promote water evaporation efficiency in high-salinity brine. Herein, a molecularly engineered zwitterionic hydrogel is developed and the incorporated phenyl-methylene-imidazole motif greatly enhances the salt binding ability and strengthens anti-polyelectrolyte effect, leading to boosted hydration, improved salt tolerance, ultra-low evaporation enthalpy (almost half of traditional zwitterionic gel), and durable anti-microbial ability in brine. Besides, gradient solar-thermal network is penetrated to optimize water transport channel and heat confinement. The gel exhibits excellent evaporation rate of 3.17 kg m −2 h −1 in seawater, which is 1.6 times of that in water and such high efficiency could be maintained during 8 h continuous desalination, demonstrating outstanding salt tolerance. The high flux of ion stream can generate considerable voltage (321.3 mV) simultaneously. This work will bring new insights to the understanding of anti-polyelectrolyte effect at molecular level and promote materials design for saline water evaporation.

Ciprofloxacin hydrochloride is widely used to treat animal diseases. However, its chronic abuse has caused severe accumulation in animal-derived foods , which has seriously damaged human health. Thus, in this study, a novel molecularly imprinted electrochemical sensor (MIES) was designed for selective and ultra-sensitive detection of ciprofloxacin hydrochloride (CPFX) in milk. The sensor was based on the molecularly imprinted polymers (MIPs) synthesized with poly-pyrrole (PPy) as the functional monomer , AuNPs and S-CoFe-MOFs (CoFe-Metal organic frameworks coated with chitosan) as the Supporting materials , and CPFX as the template molecule. The electrochemical behavior of MIPs/S-CoFe-MOFs/AuNPs/GCE was studied by several electrochemical methods, which showed a wider detection linear range (0.05 ∼ 500 ng·mL -1 ) and lower detection limit (0.0033 ng·mL -1 ) than those in previous reports. The optimization of experiments confirmed the good selectivity and stability of the sensors----- with the milk sample recovery of 89.04∼110.26%, and the relative standard deviations (RSD) of less than 5.5%, which was close to HPLC. In conclusion, the sensor we constructed has a high selectivity and stability potential in detecting CPFX in milk.

Solar-driven interfacial water evaporation can be exploited for freshwater generation with clean and pollution-free characteristics. The transport of water molecules from bulk water to the surface of the absorber is a key factor for efficient water evaporation. Herein, an oil body (OB), a spherical organelle extracted from safflower seeds, was used as supporting materials due to its low density and hydrophilic surface. After in situ polymerization of polypyrrole (PPy) in the interior of OB, an OB-PPy absorber with excellent photothermal performance and water transporting ability was obtained. When adding OB-PPy into sewage or seawater, it shows higher water evaporation rate and freshwater collection capabilities than PPy alone. The highest evaporation rate (2.11 kg m -2 h −1 ) and evaporation efficiency (92.02 %) can be obtained in OB-PPy containing rainwater. The freshwater collection rate can reach 1.38 kg m -2 h −1 when using a homemade freshwater collection device. Moreover, OB-PPy exhibits long term stability and reusability. Interestingly, we have found that OB-PPy lyophilized powder could absorb atmospheric water and produce freshwater from humid air. Therefore, OB-PPy holds great potential for solving the problem of freshwater resource shortage.

Exosomes, which can be used to investigate various disease processes, are novel disease markers that have been extensively studied in recent years. In this work, zirconium-rich porphyrin-based porous organic polymers (Imi-Pops-Zr) were synthesized by a facile and low-cost strategy for specific enrichment and isolation of phosphorylated peptides and exosomes. The proposed material demonstrates a low detection limit (0.5 fmol), a high selectivity (bovine serum albumin (BSA): β-casein = 1000:1), and a loading capability of 100 mg/g for phosphopeptides. For complex practical samples, after enrichment with Imi-Pops-Zr, 4 characteristic phosphopeptides from human serum, 20 and 12 phosphopeptides from human saliva and defatted milk were detected, respectively. Besides, 74 phosphorylated peptides with 67 phosphorylation sites belonging to 61 phosphoproteins and 67 phosphorylated peptides with 63 phosphorylation sites belonging to 65 phosphoproteins were detected from the serum of normal controls and uremic patients, respectively. Biological processes, cellular components and molecular functions revealed that interleukin-6, tumor necrosis factor, high density lipoprotein and proteases binding may be associated with uremia. Furthermore, Imi-Pops-Zr was successfully used to enrich and isolate exosomes from human serum. The experimental results show that Imi-Pops-Zr has promising application in the specific enrichment of phosphorylated peptides and exosomes in complex bio-samples.

As a promising anode for sodium-ion batteries (SIBs), cobalt sulfide (CoS 2 ) has attracted extensive attention due to its high theoretical capacity, easy preparation, and superior electrochemical activity. However, its intrinsic low conductivity and large volume expansion result in poor cycling ability. Herein, nitrogen-doped carbon-coated CoS 2 nanoparticles (N–C@CoS 2 ) were prepared by a C 3 N 4 soft-template-assisted method. Carbon coating improves the conductivity and prevents the aggregation of CoS 2 nanoparticles. In addition, the C 3 N 4 template provides a porous graphene-like structure as a conductive framework, affording a fast and constant transport path for electrons and void space for buffering the volume change of CoS 2 nanoparticles. Benefitting from the superiorities, the Na-storage properties of the N–C@CoS 2 electrode are remarkably boosted. The advanced anode delivers a long-term capacity of 376.27 mAh g −1 at 0.1 A g −1 after 500 cycles. This method can also apply to preparing other metal sulfide materials for SIBs and provides the relevant experimental basis for the further development of energy storage materials.
