Chlorothalonil is a widely used fungicide that has a negative effect on individual movement, but its impact pathway needs further refinement. Here, the effects of exposure to chlorothalonil on the locomotion behavior of Pelophylax nigromaculatus tadpoles (GS23) were measured at three different levels (0 µg/L, 10 µg/L, and 50 µg/L), and the possible pathways of its effects were analyzed from the gut-liver axis. Chlorothalonil exposure levels of 10 µg/L and 50 µg/L significantly reduced the average speed of P. nigromaculatus tadpoles by 26% and 32.7%, respectively, and significantly decreased the locomotor frequency by 27.1% and 58.6%, respectively. Gut microbiota analysis revealed chlorothalonil exposure significantly increased the abundance of Firmicutes , while significantly decreased the abundance of Actinobacteriota , Pseudomonas , and Rhodococcus . Metabolomics analysis identified that chlorothalonil treatment changed amino acid-related metabolism pathways in the gut and liver and altered the glycerophospholipid metabolism pathway in the liver. This study indicated that chlorothalonil can affect individual locomotor abilities and interfering with the gut-liver axis of aquatic animals. These findings establish that chlorothalonil compromises aquatic organism motility through a multi-target mechanism involving gut microbiota modulation, amino acid metabolic interference, and hepatic lipid pathway disruption.

Ideal conductive hydrogels with their mechanical ductility, high conductivity and self-adhesion are essential for potential promising application as fascinating sensing materials in wearable electronic devices. Unfortunately, due to the inevitable performance degeneration stemming from swelling features in aqueous conditions, the applicability of hydrogel-based sensors is greatly reduced in aquatic environments. Herein, an amphibious hydrogel with mechanical ductile, self-adhesive, anti-freezing, and high strain sensitivity underwater is developed. The hydrogel produces a rapid self-gelation behavior at ambient conditions (several minutes) through a catechol redox reaction based on lignocellulosic nanofibril-Ag + . The tough polymer network by the virtue of strong hydrogen bonding and nano-reinforcement enables the resultant hydrogel with improved mechanical performance. Meanwhile, outstanding properties including high conductivity (2.12 S/m), strain sensing ability (maximum GF: 3.98), good water resistance (equilibrium swelling ratio of 1.2% after 30 d) as well as other solvents, air/underwater adhesiveness, and anti-freezing performance can be obtained simultaneously. A sensor based on such hydrogel can be conveniently conformed and attached to the human limbs for achieving non-invasive, high stability and continuous underwater communications and habits tracking of marine. Briefly, this work provides an innovative route to develop multifunctional integration hydrogel-based flexible devices for information transmission in marine environments.

Janus films with asymmetric properties on opposite sides have been widely used to facilitate energy storage, ion transport, nanofiltration, and responsive bending. However, studies on Janus films rarely involve controlling surface adhesion, either dry or wet adhesion. Herein, we report Janus adhesive tape with an asymmetrically crosslinked polydimethylsiloxane (PDMS) network prepared through an interfacial hydrosilylation strategy, realizing wet/dry amphibious adhesion on various solid surfaces. The lightly crosslinked side of the Janus adhesive tape acts as an adhesive layer with high adhesion, and the highly crosslinked side functions as a supporting layer with high mechanical strength. This Janus adhesive tape with good adhesion and mechanical properties can be dyed different colors and can act as an underwater adhesive and a skin adhesive for wearable electronic devices. This study provides a promising design model for next-generation adhesive materials and related applications.

We have recently developed a novel and simple approach based on aqueous solutions of block copolymer micelles for the construction of WFs with wettability ranging from the superhydrophobic to the superamphiphobic regime. That is, the copolymers were initially dispersed into water to yield a micelle solution with the insoluble fluorinated block serving as the micellar core and the water soluble block as the micellar corona. The polyethylene terephthalate (PET) or cotton WFs were then dipped into a copolymer micelle solution and then naturally dried at room temperature before they were cured at high temperature to yield WFs with various degrees of liquid repellency. Further investigation on the mechanism for the formation of either superhydrophobic or superamphiphobic WFs using this aqueous process would facilitate the commercial applications of these water-based coatings. In this contribution, polyethylene terephthalate (PET) films with different liquid repellencies based on copolymer aqueous micelle solutions were prepared via previously reported process, and AFM and XPS techniques were respectively employed to evaluate the morphology and chemical composition of the copolymer-coated PET films. The dependence of water and oil contact angles of PET films on the concentrations of the copolymer micelle solution were evaluated and further employed for the prediction different liquid repellencies of PET WFs. The mechanism for the formation of the superhydrophobic WFs or superamphiphobic WFs was also proposed.

Three kinds of long-side-chain-modified tadpole-type anion exchange membranes (AEMs) named QPEK-DMODAs with microphase separated structures designed for electrodialysis (ED) acid recovery were fabricated from N,N-dimethyloctadecylamine (DMODA) as quaternization agent and poly(arylene ether ketone) (PEK) as skeleton, which is the copolymer of 2,2′,6,6′-tetramethyl biphenol (TMBP) and 4,4′-difluorobenzophenone (DFBP). QPEK-DMODAs were characterized systematically including basic structures and properties, ED recovery performance of H 2 SO 4 solutions without or with metal impurities, and corrosive acid stability. The well-defined microphase separation structure of QPEK-DMODA-3 is formed by the suitable distribution of tadpole ionic groups at the highest IEC of 2.09 mmol g −1 . The aggregate structure offers the membrane competent mechanical stability, ion conductivity and permselectivity, as well as low energy consumption and water transport ratio at the ED process. QPEK-DMODA-3 exhibits higher current efficiency (54.58 %) and recovery H + concentration (1.74 M) than those of QPEK-DMODA-1, QPEK-DMODA-2 and commercial AMX with comparable energy consumption to that of AMX under the ED conditions of Fe 2+ absence. Moreover, the Fe 2+ removal rate (88.74 %) and ion selectivity (S = 57.32) of QPEK-DMODA-3 are remarkably higher than those of AMX (67.10 % and 17.32) without the scarce of recovery efficiencies in the ED recovery tests of 0.50 M H 2 SO 4 solution containing 0.10 M of Fe 2+ . The combination of the comparable tolerance to strong acid to that of AMX and the confirmed good ED recovery performances declares a strong potential of tadpole-type QPEK-DMODA-3 in waste acid recovery by electrodialysis.

Conductive hydrogel endures as an ideal candidate for flexible electronic devices. However, conventional conductive hydrogels cannot incorporate superior sensitivity under low deformation, biocompatibility and underwater sensing into one system, which widely obstructs their applications in an aqueous environment. Herein, we designed a supramolecular conductive poly(vinyl alcohol) (PVA) and tannic acid (TA) based PVA/TA hydrogel. Due to the effective hydrogen bonding between PVA and TA, the hydrogel possesses some unique properties, including anti-swelling, stretching, self-healing and shape-memory. The PVA/TA supramolecular hydrogel demonstrates an excellent electrical performance where the conductivity and gauge factor (GF) are obtained at 5.5 × 10 -4 S/cm and 1.3 in dry and 5.0 × 10 -4 S/cm and 1.2 in wet conditions, respectively. The multifunctional hydrogel manifests excellent mechanical properties, where the maximum tensile strength of the hydrogels is 700 kPa at an elongation of 4700 %. Additionally, the hydrogel possesses excellent shape-memory and self-healable properties. Moreover, the hydrogel depicts outstanding biocompatibility, anti-swellable properties and exerts long-term stability underwater to detect human motions. Based on excellent anti-swelling and stability, high electrical conductivity and extraordinary stretching capability, the hydrogels may consider as promising candidates for applications in amphibious motion sensors.

Passive radiative cooling (PRC) is a promising technology to achieve eco-friendly building cooling relying on automatic solar reflection and thermal emission. However, sewage, oil and even dust in actual application often cause irreversible damage of surface optical selectivity required by durable cooling. Herein, ZnAl LDO biomimetic microflowers are fabricated as optically selective substrate following by crosslinking of superamphiphobic (SAP) SiO 2 nanoparticles to obtain inorganic SAP-PRC coating. Openly-porous micro-nano-structure from LDO microflowers imparts the coating excellent solar reflectivity (∼97.58% normalized with BaSO 4 ) and thermal emissivity (∼98%) as well as efficient resistance for both water (contact angle >158°/slide angle <5°) and oil (contact angle >151°/slide angle <10°). As the result, the coating achieves about 7℃ of cooling effect under (>1400 W/m 2 ) of solar radiation and ∼5℃ lower than the commercial coating. The superamphiphobic surface help SAP-PRC coating avoid over 7.5℃ increase of temperature under >1500 W/m 2 after being immersed by oil pollution. It is estimated that the cooling coating can help achieve ∼26% energy saving in hot areas (Haikou in China) throughout a year also considering warming-energy consumption in winter. The synergistic self-cleaning and optical selectivity strategy will effectively promote the commercialization of building PRC materials and further contribute to energy and environment sustainability.

Porous media with directional water-transport capability have great applications in oil–water separation, moisture-harvesting, microfluidics, and moisture-management textiles. However, the previous directional water-transport materials chiefly work in the air. The materials with directional water-transport capability in the oil phase have been less reported. Here, we fabricated a novel Janus fabric with amphibious directional water-transport capability that can work both in the air and oil phases. It was prepared using dip coating and spraying to develop an oleophobic-hydrophobic to oleophobic-hydrophilic gradient across the thickness of the fabric substrate. The fabric allowed water droplets to rapidly transport from the hydrophobic to the hydrophilic side when the fabric was either in the air environment or fully immersed in oil. However, it hindered water transport in the opposite direction. More importantly, the fabric can overcome gravity to capture water from oil. Such an air–oil amphibious water-transport fabric showed excellent water collecting capability. In oil, it does not require any prewetting or extra pressure to perform directional water transport, which is vital for water–oil separation and microfluidics. Such amphibious directional water-transport function may be useful for the development of smart membranes and directional liquid delivery.

A facile and flexible method to prepare raspberry-like nanoparticles that can be used as a superamphiphobic coating is reported. Anatase TiO 2 nanoparticles were chosen as the core because of their irregular morphology and photocatalytic performance. Anatase TiO 2 nanoparticles were surrounded tightly by tiny functional fluoride–silica nanoparticles via the hydrolysis-condensation reaction of tetraethoxysilane and 1H, 1H, 2H, 2H-perfluorodecyl triethoxysilane. The obtained Si–F@TiO 2 nanoparticles can be sprayed or dipped directly onto various substrates. The coated film exhibited quite good liquid resistance, even when subjected to water jetting and sand abrasion. The photocatalytic effect of the coated anatase TiO 2 with respect to formaldehyde was also studied and discussed. This method will provide more opportunities and fast access to practical applications in surface, environmental, and energy engineering.

Surfaces with uniform and stable superwetting behavior have enormous application prospects. In particular, an air-water/oil amphibious superhydrophilic-superhydrophobic surface is advantageous in oil-water separation and oil-repellent materials. However, existing methods to create this property require either water pretreatment or time-consuming stimulation process, which makes instant oil-water identification impossible. Here, inspired by Namib desert beetle, we propose a strategy to construct layers differing in surface free energies to achieve surfaces that are simultaneously superhydrophilic-superoleophobic. Rough microcrystalline cellulose particles were modified by 2,2,6,6-tetramethyl-1-piperidinyloxy and perfluorooctanoic acid to successively construct high- and low-surface free energy layers. Surfaces prepared by simple spraying of these particles display excellent and stable superhydrophilicity-superoleophobicity under the amphibious conditions of air and water/oil, as well as excellent temperature and abrasion resistance. Pressed cotton membranes treated with these particles can effectively separate oil-water mixtures and oil-in-water emulsions without any pretreatment, even when the oil phase is highly viscous. Moreover, cotton gloves coated with these particles have superior water permeability and oil repellency without losing breathability. These results suggest a new approach towards oil-water separation and oil-repellent fabrics.

Transparent actuators have significant potential in invisible and camouflage robots. However, traditional transparent actuators are typically unprogrammable and used in a single environment (on-land or in-water), which limits their working abilities in complex environments. Herein, we propose transparent actuators and robots that integrate amphibious actuations, programmable motions, self-healing function and camouflage function together. The actuator is composed of MXene polymer composites, including bone glue, gelatin, MXene (BGGM) and polyethylene terephthalate (PET). The transmittance of BGGM/PET actuator is >80 % at 600 nm wavelength, exhibiting high transparency. On one hand, the actuator shows a light-driven bending deformation on land due to the photothermal effect. Synergistic combination of the self-healing of BGGM and the shape-fixing of PET allows the spatial-programming of actuator to demonstrate light-driven complex deformations. On the other hand, the actuator can be driven by Marangoni effect on water by using BGGM composite as fuels. Adding functional modules enables the spatial-temporal programming of the actuator, so the actuator can showcase time-varying trajectories. Finally, we demonstrate a transparent swimming robot with dual-actuation modes and a transparent actuator that conveys invisible information stealthily while moving through a complex maze on water. This research offers a promising approach to camouflage amphibious robots.

Multifunctional coatings are in urgent demand in emerging fields. In this work, nanocomposite coatings with extraordinary self-cleaning, antiwear, and anticorrosion properties were prepared on aluminum substrate by a facile spraying technique. Core–shell structured polyaniline/functionalized carbon nanotubes (PANI/fCNTs) composite and nanosized silica were synergistically integrated into ethylene tetrafluoroethylene (ETFE) matrix to construct lotus-leaf-like structures, and 1H,1H,2H,2H- perfluorooctyltriethoxysilane (POTS) was used to decrease the surface energy. The composite coating with 6 wt % PANI/fCNTs possesses superamphiphobic property, with contact angles of 167°, 163°, and 159° toward water, glycerol, and ethylene glycol, respectively. This coating demonstrates stable nonwetting performance over a wide temperature range (<400 °C), as well as outstanding self-cleaning ability to prevent contamination by sludge, concentrated H2SO4, and ethylene glycol. Superamphiphobic surface property could be maintained even after 45 000 times abrasion or bending test for 30 times. The coating displayed strong adhesive ability (grade 1 according to the GB/T9286) on the etched aluminum plate. The superamphiphobic surface could be retained after immersion in 1 mol/L HCl and 3.5 wt % NaCl solutions for 60 and 90 d, respectively. It should be noted that this coating reveals significantly improved anticorrosion performance as compared to the bare ETFE coating and ETFE composite coating without PANI/fCNTs. Such coatings with integrated functionalities offer promising self-cleaning and anticorrosion applications under erosive/abrasive environment.
