Synergistic T g reduction via GO alignment and NGDE flexible chain modification. • MD simulations deconvolute free volume expansion and interfacial disruption mechanisms. • Sub-additive interaction between dual modification strategies revealed at molecular level. • The optimized composite achieves 58% reduction in deicing time at −15 °C. Shape memory polymers (SMPs) facilitate ice removal by undergoing stimulus-induced deformation that weakens the ice–substrate interface. However, the high glass transition temperature ( T g ) of epoxy-based SMPs increases the activation temperature and limits low-temperature use. In this study, T g was regulated through a dual strategy combining flexible-chain modification with field-assisted alignment of graphene oxide/magnetic graphene oxide (GO/MGO) nanosheets. Neopentyl glycol diglycidyl ether (NGDE) was introduced into the epoxy network as a reactive aliphatic modifier. GO/MGO nanosheets were aligned to form interfacial regions and preferential heat-transfer pathways. Thermal analysis, shape-memory tests, and de-icing experiments were performed to evaluate the composites. Molecular dynamics simulations using the COMPASS III force field were employed to analyze changes in specific volume and free volume and to clarify the underlying molecular basis of T g regulation. The combined GO/MGO alignment and NGDE modification lowered T g from 64.9 to 38.2 °C while maintaining a shape recovery ratio of 91.1%. De-icing tests at −15 °C show that the modified EP composite reduces both de-icing time and energy consumption by 58% compared with pristine EP, indicating its potential as a low-temperature shape memory de-icing material.

Organic coatings are ideal candidates for mitigating corrosion and mechanical wear of metal-based substrates due to the effective physical barrier capacity in marine environments. However, their performance is often compromised by inherent defects, alternating hydrostatic pressure (AHP), and mechanical wear, ultimately resulting in coating failure and substrate corrosion. This study presented a high-performance composite coating by integrating core-shell nanohybrids (GO@pPTFE) into waterborne epoxy resin matrix. The combination of low surface energy PTFE core and GO nanosheets featuring abundant functional groups not only balanced high hydrophobicity and strong adhesion but also endowed the coating with outstanding corrosion resistance (|Z| 0.01 Hz value of 8.7 × 10 9 Ω·cm 2 even after 30 cycle of immersion under 20 MPa AHP environment). Furthermore, the resulting coating exhibited stable low coefficient of friction (0.027), excellent anti-wear property (wear rate of 0.96 × 10 −6 mm 3 ·N −1 ·m −1 ), narrow wear track width (195 μm), and slight wear tracks. These significant improvements were mainly ascribed to the robust interfacial adhesion, effective barrier properties, robust interfacial adhesion, and synergistic wear reduction effects associated with the constructed GO@pPTFE core-shell nanohybrids, making the coating a promising strategy for deep-sea corrosion and wear challenges.

The slow rate of the Fe3+/Fe2+ cycle has decreased the efficiency of photo-Fenton technology for wastewater treatment. Here, a novel GO/MIL-100(Fe)@Fe3O4 heterostructure was constructed by growing Fe3O4 nanoparticles and MIL-100(Fe) onto GO, thus accelerating the Fe3+/Fe2+ cycle and improving catalytic activity, and it was used as a heterogeneous photo-Fenton catalyst for ERY degradation. The catalyst was fully characterized by TEM, XRD, Raman spectroscopy, XPS, N2 adsorption–desorption and UV-vis DRS. The influences of initial solution pH, H2O2 concentration and catalyst dosage on ERY degradation were investigated. Under optimal conditions (initial pH of 4.03, 10.0 mM H2O2, 0.1 g L−1 catalyst), the GO/MIL-100(Fe)@Fe3O4 + H2O2 + vis system removed 97.3% of ERY (0.1 mmol L−1) within 60 min, and the pseudo-first-order rate constant was 0.0575 min−1. Furthermore, the catalyst showed favorable stability, maintaining excellent catalytic activity even after 4 cycles. A possible degradation mechanism of ERY was proposed based on the results of characterization, ERY degradation, and reactive species analysis. Fe3O4, MIL-100(Fe) and GO in the catalyst showed synergistic effects; the photo-induced electrons from MIL-100(Fe) could be immediately transferred to Fe3O4, promoting Fe3+ reduction to Fe2+ in the photo-Fenton reaction. GO in the catalyst could promote electron transfer from MIL-100(Fe) and organics to Fe3O4, significantly promoting the Fe3+/Fe2+ cycle.

The easy preparation of robust superwetting materials for oily wastewater disposal still remains a challenge. Inspired by the self-cleaning and mechanical properties of natural nacre underwater, herein, we have successfully developed sphere-rod quaternary artificial nacre-inspired meshes (named GO-PEI-SiO 2 -Hal) via interfacial self-assembly using 2D graphene oxide nanosheets , hyperbranched polyethyleneimine, SiO 2 nanospheres , and hollow halloysite nanotubes (Hal) as the building blocks. The nacre-like “brick-and-mortar” layered microstructure was successfully formed and tightly coated to the mesh, showing excellent mechanical properties with Young's modulus up to 19.7 ± 2.6 GPa. Compared to the ternary structures, the quaternary sphere-rod morphology improved the surface roughness , and these four organic/inorganic building blocks are all hydrophilic , which together resulted in the superhydrophilic and underwater superoleophobic characteristics. The effects of building block concentration, dipping number, and mesh size on wettability and oil-water separation performance were studied in detail. The optimal (GO-PEI-SiO 2 -Hal-1) 15 @Fe 300 mesh showed an underwater oil contact angle of 159 o for 1,2-dichloroethane, low oil adhesion, and excellent separation efficiency up to 99.8% at an ultrahigh flux up to 195,038 L m −2 h −1 . This nacre-like mesh exhibited excellent salt tolerance, acid-alkali resistance, recycling ability, and mechanical properties for practical oily wastewater treatment .

A sandwich electrochemiluminescence (ECL) immunosensor based on an N-(4-aminobutyl)-N-ethylisoluminol-graphene oxide-Ag nanoparticle (ABEI-GO-AgNPs) complex and cysteine silver nanowires (AgCysNWs) was prepared to detect prostate-specific antigen (PSA). Our results showed that an ECL signal probe, ABEI-GO-AgNPs, with an ultrahigh specific surface area, favorable catalytic properties, and electrical conductivity was prepared by a one-step synthesis method. ABEI-GO-AgNPs with good biocompatibility immobilized secondary antibody (Ab 2 ) via Ag N bonds. Furthermore, AgCysNWs containing many –COOH groups were prepared and used to enrich primary antibody (Ab 1 ), which could be used as an affinity probe for the selective capture of PSA. Lastly, through layer-by-layer assembly, we established an ECL immunosensing platform for the sensitive detection of PSA. Under the optimized conditions, the designed ECL immunosensor showed promising sensitivity and selectivity for the detection of PSA in the linear range of 5.5 × 10 −7 –5.5 ng/mL, with a detection limit of 1.2 × 10 −7 ng/mL. The constructed ECL sensing platform possessed good specificity, reproducibility, and stability and could detect PSA in actual human serum samples.

It plays an important role to effective detection of amphenicols antibiotic residues in food and an important issue considering of possible impact on human health. In this work, the molecularly imprinted membranes (MIMs) were proposed to simultaneously recognize and detect thiamphenicol (TAP), florfenicol (FF) and chloramphenicol (CAP) in pork and milk samples. The synergistic effect of graphene oxide (GO), double functional monomer (methacrylate and acrylamide) and “click chemistry” strategy prompted the membranes to possess good surface hydrophilicity (48.6°), excellent selectivity and capacity to exclude macromolecules. The theoretical models of selectivity mechanism showed the selective recognition depended mainly on the hydrogen bond interaction and van der Waals interaction between the analytes and monomers. The limit of detection for 3 analytes were 0.04–0.28 µg kg −1 , and showed a good correlation ( r > 0.9949). Finally, this study established an effective MIMs-UHPLC-MS/MS method with great potential for the monitor of antibiotics residue in complicated matrices.

The combination of photocatalysis and Fenton oxidation technology is an efficient strategy to improve the efficiency of oxytetracycline hydrochloride (OTC-HCl) degradation. Herein, a Fe 3 O 4 @GO@MIL-101 composite catalyst bridged with graphene oxide (GO) was obtained by a two-stage hydrothermal method . The introduced graphene oxide layer could inhibit the recombination of electron hole (e − - h + ) pairs by attracting photo-generated electrons from MIL-101 and transferring them to Fe 3 O 4 , observably enhancing the photocatalytic performance of the composite Fe 3 O 4 /MOFs. Under the optimal conditions (initial pH, 10 mmol H 2 O 2 , 0.01 g/L catalyst), the Fe 3 O 4 @GO@MIL-101 + H 2 O 2 +Vis system could achieve a degradation effect of 97.26 % on 70 mg/L OTC-HCl within 50 min Fe 3 O 4 @GO@MIL-101 nanocomposites exhibited good recyclability , were easy to recover after multiple uses, and maintained excellent removal efficiency for pollutants. A series of data demonstrated that in Fe 3 O 4 @GO@MIL-101 + H 2 O 2 +Vis system, the primary active substances involved in OTC-HCl degradation were holes and superoxide radicals , while the contributions of hydroxyl radicals and photo generated electrons were relatively weak. Finally, based on various characterization results and catalyst activity performance, a feasible mechanism for the removal of OTC-HCl by Fenton-like system was proposed.

Attapulgite/carbonylated graphene oxide (ATP/GO-COOH) composite membranes have been successfully prepared by vacuum-assisted filtration of an aqueous ATP/GO-COOH dispersion on a microfiltration substrate. Due to the interaction between the OH groups of ATPs and COOH groups of GO-COOH, ATP rods showed excellent compatibility with GO-COOH nanosheets , and the ATP mass fraction was significantly improved. The large amount of ATP can establish a fast transport channel for the diffusion of water molecules in the composite membrane. As a result, the optimum membrane gave a permeation flux with 13582 L/(m 2 h), which is significantly higher than that of the pure GO-COOH membrane (2281 L/(m 2 h)). In addition, the underwater superoleophobic properties of the ATP/GO-COOH composite membrane enable it to have a low oil-adhesive water/membrane interfaces. The ATP/GO-COOH composite membrane showed good separation and separation stability for oil-in-water emulsion systems with different concentrations, pH, and oil types.

In the marine environment, besides external damage and internal defects, ultraviolet (UV) radiation is also a pivotal factor affecting the stable properties of coatings. Improving the anti-UV aging and active protection properties is beneficial to prolong the service life of coatings. Herein, the PDA-GO-CeO 2 composite material is obtained through a facile stepwise growth of polydopamine (PDA) and CeO 2 on GO nanosheets and further preparing a multifunctional anti-corrosion PDA-GO-CeO 2 -EP coating. As expected, composite coating displays strong adhesion force (6.9 MPa) and tensile strength (21.1 MPa), profiting from the enhanced crosslinking density and interface structure caused by PDA-GO-CeO 2 and resin matrix interaction. Since low defect functionalized PDA-GO-CeO 2 constructs the reinforced physical barrier, the anti-corrosion ability of PDA-GO-CeO 2 -EP coating (10 9.7 Ω·cm 2 ) is more dependable than those of EP (10 6.7 Ω·cm 2 ), GO-EP coating (10 8.8 Ω·cm 2 ) and PDA-GO-EP (10 9.1 Ω·cm 2 ) coatings after immersing in 3.5 wt.% NaCl solution for 100 d. Thanks to the synergistic effect of PDA/CeO 2 , the active protection performance of PDA-GO-CeO 2 -EP coating is endowed, which is further proved through the in situ scanning vibrating electrode technique (SVET). Following the UV aging treatment, PDA-GO-CeO 2 -EP coating shows minor gloss loss (20.4 %) and better adhesion force (4.3 MPa). Furthermore, the resistance value of PDA-GO-CeO 2 -EP coating is 7.03 × 10 6 Ω cm 2 after 30 d immersion in saline solution, which is 242 times greater than that of EP coating (2.90 × 10 4 Ω cm 2 ). This dependable performance of PDA-GO-CeO 2 -EP coating comes from the reflection, refraction, and absorption of UV rays by nanoscale CeO 2 particles. Consequently, this work offers a simple and promising strategy for fabricating multifunctional long-term protection coatings, thus hopefully extending the service life of marine engineering equipment.

Molybdenum disulfide (MoS 2 ) has become a promising low-cost alternative to Pt catalyst for electrochemical Hydrogen evolution reactions (HER). However, the poor conductivity and limited active sites of thermodynamically stable 2H-Phase MoS 2 hinder its catalytic performance. Utilizing phase engineering to convert 2H MoS 2 to metallic 1 T MoS 2 is an effective strategy to improve the catalytic activity of MoS 2 . The commonly used synthetic and phase engineering methods such as electrochemical exfoliation involve using a complicated synthesis route or under strict experimental conditions or both. Herein, we develop a one-pot hydrothermal method to in-situ synthesize a 2D (1 T MoS 2 )/2D (GO) heterostructure with a face-to-face contact between the ultrathin MoS 2 (few layers) and Graphene oxide (GO). The content of 1 T MoS 2 in the prepared 1 T MoS 2 /GO reaches as high as 76.7%. When used as a catalyst, 1 T MoS 2 /GO exhibited an outstanding HER performance, with a small overpotential of 209 mV at a cathode current density of 10 mA cm −2 , and an extremely low Tafel slope of 45.5 mV Dec −1 , which is very close to that of Pt/C (40.0 mV Dec −1 ). Moreover, it demonstrated an excellent stability after a storage of 212 days in air. The high electrocatalytic performance could be attributed to the high 1 T-phase content in the MoS 2 , as the 1 T phase provides numerous active sites and improves the electronic conductivity of the catalyst. Strong interactions between 1 T MoS 2 and GO substrate stabilizes the structure of the 1 T MoS 2 and allows rapid charge transfer kinetics. This work proposes a facile and effective strategy for the design and synthesis of transition metal chalcogenides with high HER performance.

Due to the bonding force between the surface Co atom and the adsorbed intermediate are so strong that intermediate cannot desorb from Co atom, the oxygen reduction reaction of Co 2 P based electrocatalyst cannot satisfy the commercialized application of the Zn-air battery. In this work, a GO-induced assembly strategy was designed to construct cobalt phosphide (Co 2 P) nanoparticles encapsulated in N-doped carbon nanotubes (Co 2 P@NCNTs). The experimental results show that adding graphene oxide (GO) content has a significant impact on the formation of well-defined Co 2 P@NCNTs nanotubes structures and the exaltation of the graphitization degree. Benefitting from the synergistic effect between N-doped nanotubes and Co 2 P, the Co 2 P@NCNTs-15 electrocatalysts exhibited better catalytic performance, a more positive onset potential (0.90 V vs RHE) and half-wave potential (0.82 V vs RHE), maximum limiting diffusion current density (5.5 mA cm −2 ) and Tafel slope only 73 mV dec −1 . The potential gap (ΔE) between E j=10 of OER and ORR half-wave potential (E 1/2 ) of Co 2 P@NCNTs-15 is only 0.93 V, which lower than Pt/C electrocatalyst (1.15 V). More importantly, the Co 2 P@NCNTs-15-based rechargeable Zn-air battery performed the highest peak power density (159.7 mW cm −2 ), specific capacity (792.6 mAh g −1 at 10 mA cm −2 ) and remarkable cycle stability. This method also offers a high yield and cost-effective synthesis strategy for preparing the other transition metal phosphide electrocatalysts.
