Adhesives have been increasingly utilized in multifaceted applications, such as furniture, electrical appliances, and buildings. Currently, in addition to fundamental requirements for high adhesiveness, there are increasing demands for environmental sustainability, flame retardancy, and high-performance in extreme conditions. (6H-dibenz[c,e][1,2]oxaphosphorin-6-ylmethyl)-p-oxide-butanedioic acid (DDP) is selected to be incorporated into the Poly(butylene adipate-co-terephthalate) (PBAT) backbone, enabling the synthesis of a novel adhesive (poly(butylene adipate-co-terephthalate-co-phosphaphenanthrene) (PBATDn). Due to the π-π stacking of DDP, PBATD 20 exhibits an extremely high adhesion strength of 11 N/cm. Owing to the hydrophobicity of the aromatic ring and the insensitivity of π-π stacking to water, PBATD 20 maintains a high adhesion even after being immersed in water for 15 days, thus meeting the requirements for wet-environment applications. In addition to meeting the demand for adhesives, PBATD 20 has been shown to reduce the potential fire risk. DDP releases phosphorus-oxygen free radicals to capture the ·H or ·OH radicals generated by polymer burning, effectively inhibiting the burning process. PBATD 20 leaves some compact char residues that act as barriers to slow down the transfer of heat, oxygen, and combustible gases, showing excellent flame retardancy. Furthermore, PBATD 20 exhibits a superior biodegradation capacity in Candida antarctica lipase B (CALB) at 37 ℃ compared with PBAT, thus reducing environmental pollution. PBATD 20 is considered highly suitable for diverse applications in daily production and consumer use, including degradable packaging adhesion, electronics assembly, and the bonding of environmentally friendly building materials.

Transition-metal-atom anchored graphdiynes (TM@GDY, TM = Mn, Fe, Co, Ni and Cu) have already been synthesized and found applications in hydrogen evolution , nitrogen fixation and etc. By means of first-principle predictions and test experiments, we propose here that Fe@GDY and Co@GDY are efficient catalysts for the sustainable conversion of O 3 to O 2 . These two catalysts can spontaneously chemisorb O 3 with zero reaction barrier and have low O 3 conversion barriers (0.31 eV and 0.19 eV, respectively). The O 3 decomposition experiment in a continuous flow membrane reactor and electron paramagnetic resonance results verify that Fe@GDY and Co@GDY are efficient catalysts under humid conditions. Raman spectra prove the formation of the key Fe-O/Co-O and Fe O O and Co O O intermediates. The hydrophobic nature of graphdiyne and the strongest chemisorption of O 3 among tested ambient gases, make Fe@GDY and Co@GDY ideal catalysts under both dry and humid conditions. These findings would stimulate future explorations on metal anchored GDY-based catalysts for applications of toxic gas decomposition or fixation.

Development of supramolecular adhesion systems from small molecules is a promising strategy to construct adhesives integrating synthetic simplification and sophisticated properties. Here, we report a facile and green one-pot strategy for fabricating a solvent-free and dynamic supramolecular adhesive via co-heating three readily available feedstocks, a natural small biological molecule (α-lipoic acid), a natural plant polyphenol (tannic acid), and ferric chloride. The adhesive is injectable and self-healing, which can work instantly and repeatedly on various materials (e.g., polytetrafluoroethylene (PTFE)) in diverse conditions (dry, underwater, pH < 7, various ionic environments, and even in vacuum) at room temperature, showing promising applicability in complex environments. The self-strengthening of the supramolecular network with time further improves the adhesion strength of the adhesive for the glass (from about 22 kPa to exceeded 300 kPa after 28 d). More importantly, the adhesive exhibits great potentials to be applied in biomedical fields with wet environments. This ready-to-use and high-performance supramolecular adhesive, constructed by natural small molecules via an extremely facile preparation method, represents a promising universal strategy for both dry and wet adhesion.

Particulate matter (PM) is a significant danger to both environment and human health. Despite the development of a series of air filters, they do not work well in harsh environment such as high temperature, high humidity or long-time filtration. To make a three-dimensional (3D) particle capture device, a sacrificial template approach was used to manufacture polydimethylsiloxane (PDMS) sponge, and then zeolite imidazole framework-8 (ZIF-8) was grown in situ on the 3D network of PDMS sponge. The removal efficiency of PM 2.5 or PM 10 is greater than 99.8% because of the high specific surface area and porous network structure of PDMS sponge, as well as the large number of metal sites of ZIF-8. In addition, the sponge filter has long-term filtration stability and still achieves excellent performance after 65 h of filtration. The composite sponge can adapt to harsh environments such as high temperature (250 °C) and high humidity (90% RH). Composite sponge filter has a regular shape, and it may be customized to any shape as required. This study provides a new idea for designing 3D high-efficiency air filters that can adapt to harsh environments.

Various adsorbents for CH 4 /N 2 separation were developed to enrich low-concentration coal-mine methane. Most are hydrophilic and cannot treat moist coal-mine methane. We report for the first time a microporous zeolitic imidazolate framework Co(dcIm) 2 (TUT-100) with superhydrophobic properties for CH 4 /N 2 separation. The CH 4 adsorption capacity and CH 4 /N 2 selectivity were as high as 45.29 cm 3 /cm 3 and 6.3 (298 K, 1 bar), respectively, which results from the suitable SOD cage size (0.80 nm). The H 2 O adsorption was lower than 6.3 cm 3 /g at 298 K and near saturated pressure due to the hydrophobic group Cl. Breakthrough experiments were carried out to indicate the significant potential for CH 4 /N 2 adsorption separation in a humid environment. The adsorption behavior of the gas mixture on the TUT-100 was investigated by the Grand Canonical Monte Carlo method and coupled with the experimental data.

Capturing volatile organic compounds (VOCs) under humid conditions using zeolites suffers from the dramatically decreasing adsorption capability with relative humidity (RH) increase. Herein, a surface-induced polymer coating method is proposed to design hydrophobic zeolite. The as-synthesized novel hydrophobic Y zeolite@hypercrosslinked polymer composite (Y@P) is demonstrated with excellent adsorption capability for VOCs. In particular, the toluene adsorption capacity of Y@P-2-80 composite is two times higher than that of Y zeolite, and the Q wet /Q dry values are 97.2% at 90 %RH, indicating that the toluene adsorption capability of Y@P-2-80 is almost unaffected by vapor. The proposed surface-induced polymer coating method provides a promising and universal strategy for effective VOCs capture under wet conditions using zeolites with enhanced hydrophobicity.

Aluminum oxide is introduced into SiC f /(SiC + B 4 C) composites to improve the surface cracking resistance after oxidizing at 1100 °C in O 2 /H 2 O (40/60) atmosphere. Research on morphology observation of oxidized composites reveals that Al 2 O 3 can lead to the formation of a dense and smooth oxidation layer, resulting in a relatively shallow oxygen penetration depth. In-depth studies on acoustic emission reveal that composites with Al 2 O 3 can improve the surface cracking resistance after oxidizing at 1100 °C in O 2 /H 2 O (40/60) atmosphere since the retention rates of σ min (first acoustic emission [AE] stress) and σ onset (AE onset stress) are significantly increased compared with virgin composites. Moreover, a small number of cumulative events and steep slope of strength–time curves at the initial stage further confirm the improvement of surface cracking resistance after oxidation.

Shearing-thinning injectable hydrogels, with a fixed 3D network structure, have significant potential for application in soft and hard tissue defect repair, drug delivery, wound dressings, etc. However, these hydrogels often exhibit poor in situ reforming ability in wet and underwater environments. In this study, a hydrogel with ultrafast in situ reforming ability in wet and underwater environments is prepared using modified sodium alginate–polyvinyl alcohol–dopamine. This hydrogel, with a double dynamic chemical crosslinking network, exhibits good in situ and ex situ self-healing abilities owing to the wet adhesion property of dopamine and the underwater rebuilding property of borate ester bonds. The strength of in situ self-healing is restored to 90.1% and 110.2% of the original strength and that of ex situ self-healing is restored to 101.3% and 123.9% of the original strength after 6 min of healing in water and phosphate buffer solution environments, respectively. The in situ reforming efficiency of the hydrogel is reported to be 86.6% within 5 min of being injected into the liquid environment owing to the contribution of in situ self-healing and ex situ self-healing. In addition, the proposed hydrogel has good cell compatibility. Therefore, it can be widely used as a biomaterial.

A series of highly-hydrophobic MIL-53-Al (MIL = Materials of Institut Lavoisier) frameworks synthesized via decoration of the Al-OH groups by alkyl phosphonic acid were developed as adsorbents for removing acetone from humid gas streams. The newly prepared materials were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), N 2 adsorption-desorption and thermogravimetric analysis (TGA). Their adsorption behaviors toward acetone vapor under dry and wet conditions were studied subsequently. Results showed that alkyl phosphonic acid was successfully grafted into MIL-53-Al skeleton through coordinating interaction with Al 3+ generating MIL-53-Al@C x ( x = 12, 14, 18). The MIL-53-Al@C x exhibited similar crystal structure and thermal stability to parent MIL-53-Al. Furthermore, the modified materials showed significantly enhanced hydrophobicity . The water vapor uptake of MIL-53-Al@C 14 decreased by 72.55% at 75% relative humidity (RH). Dynamic adsorption experiments demonstrated that water vapor had almost no effect on the acetone adsorption performance of MIL-53-Al@C 14 . Under the condition of 90% RH, the acetone adsorption capacity of MIL-53-Al@C 14 was 102.98% higher than that of MIL-53-Al. Notably, MIL-53-Al@C 14 presented excellent adsorption reversibility and regeneration performance in 10 adsorption-desorption cycles. Taken together, the strategy of metal-OH group modification is an attractive way to improve the acetone adsorption performance over metal-organic frameworks (MOFs) under humid conditions. Besides, MIL-53-Al@C 14 would be deemed as a promising candidate for capturing acetone in high moisture environment.

This study introduces innovative hydrophobic nanostructured composite deep eutectic solvents (HS-SiO 2 /DBU-EG) to overcome limitations of amine absorbents in humid CO 2 . The HS-SiO 2 /DBU-EG achieved a significantly enhanced CO 2 absorption capacity of 4.14 mol/kg and maintaining a high regeneration efficiency of 95 %, attributed to its inherent synergistically hydrophobic nanostructure. In contrast, while DBU-EG showed improved absorption under humid CO 2 but reduced regeneration performance. Spectroscopic analysis revealed that DBU-EG relies on hydrolysis-induced N-sites for absorption, but the resulting products are challenging to decompose. Conversely, HS-SiO 2 /DBU-EG utilizes the O-sites of EG as the absorption sites, a mechanism supported by thermodynamic analysis and quantum calculations demonstrating a low enthalpy change value of the reaction. Fixed-bed experiments further confirmed its efficient and continuous absorption performance. This research emphasizes the value of low-energy absorption mechanisms and hydrophobic design for advanced industrial CO 2 capture.

Metal-organic framework (MOF) is widely used in MOF-based mixed matrix membrane (MMMs) for gas separation, however, their separation in low concentration CO 2 and humid environment is a challenging problem to overcome. Herein, a MOF-based MMM with multiple fluorine sites was constructed for efficient separation of CO 2 /N 2 separation system with low concentration CO 2 under humid conditions. Introducing fluorine element sites into membrane materials can not only enhance the affinity between the membrane material and CO 2 molecules, but also make the membrane material hydrophobic, making it suitable for low concentration CO 2 separation under humid conditions. The optimized membrane composed of 10 wt% PIM-2/PIM-1 as blend polymer matrices and 25 wt% fluorinated UiO-66 as fillers exhibited CO 2 permeability of 9234 Barrer and CO 2 /N 2 selectivity of 32.97 under humid conditions of relative humidity of 65% and low CO 2 /N 2 volume ratio of 1:99. This work may provide a feasible way for the design of high-performance gas separation membranes in practical applications.

Assessment of the local strain/stress changes of adhesives is highly desirable for their service to avoid premature failure. However, monitoring local strain/stress variations in adhesives in practical settings remains challenging, especially in aqueous media. Here, an underwater structurally-colored adhesive for visualized local strain/stress monitoring in aqueous media is reported. The structurally-colored adhesive is obtained by shearing composites of poly(butyl acrylate- co -acrylic acid) copolymer and carboxylated polystyrene colloidal particles. The resultant structurally-colored adhesive exhibits underwater adhesive strength (i.e., 238 kPa for stainless steel substrates) to various substrates (e.g., metals and plastics) thanks to hydrophobic segments and carboxyl groups. Notably, they can shift color in response to external force, enabling real-time visual monitoring of localized strain/stress changes. As a proof of concept, the structurally-colored adhesive can be used to seal a leaking hole on a bottle or tube, and it can precisely visualize the localized pressure distribution, providing critical information on the adhesion performance and the local pressure. These distinctive properties make the structurally-colored adhesive suitable for application in wet environments as a real-time visual pressure tracking device.
