A facile, low-cost and environmentally-friendly technique has been developed to prepare highly conductive copper-graphene nanosheet (Cu-GNS) composite coatings on ABS (Acrylonitrile-Butadiene-Styrene) substrate. The surface activation of ABS substrate was obtained by a chrome-free and palladium-free pretreatment consisting of molecular bonding. Before electroplating Cu, the homogeneous single Ag film on ABS surface was achieved by the electroless spray-plating process. In addition, the deposition of Cu and GNS increased in the coatings along with the current density increasing. Four-point-probe test confirmed that the resistivity of Cu coatings (0.08 mΩ mm) and Cu-GNS composite coatings (0.05 mΩ mm) was in the same order of magnitude as pure copper (0.0175 mΩ mm) at high current density. Meanwhile, comparing with the Cu coatings, the resistivity of Cu-GNS composite coatings was reduced by nearly 40% at the same current density. The conductive property was significantly improved owing to the deposition of GNS. Therefore, this work was expected to expand the method of polymer materials surface metallization.

In this paper, a robust and magnetic recyclable 3D superhydrophobic material (SHM) was successfully prepared through a simple, low-cost, and environmentally friendly method. A rough surface structure of the 3D SHM could be easily obtained by the electrodeposition of metallic copper on the Ni foam and a different micro-nano structure could be obtained by adjusting the electrodeposition time. Subsequently, 1-octadecanethiol self-assembled on the micro-nano structure could lower the surface energy and protect the copper coating. The 3D SHM presents high superhydrophobicity. In addition, the as-prepared 3D SHM shows outstanding chemical and secular stabilities after it was treated with solutions with a wide range of pH values. High stabilities and good superhydrophobicity with hierarchical micro-nano structure endow the 3D SHM with highly efficient and stable oil-water separation capacity. In addition, a mini boat was made using the 3D SHM to collect oil spill. We hope that this robust 3D SHM will be widely used for oil-water separation and oil spill collection.

In our previous work, we found that hydrogen permeation can be noticeably reduced during Ni–Cu electroplating by the addition of Ce salt to the plating solution. The mechanism of hydrogen permeation inhibition via Ce salt was further studied in the present work. Through the Iver–Pickering–Zamenzadeh (IPZ) model fitting of the kinetic of hydrogen evolution reaction , we found that the trace Ce salt that precipitated during electroplating could improve Tafel reaction kinetic parameters and reduce the strength of the Ni–H and Cu–H bonds due to its abundant d/f electrons and enough d/f orbitals. Meanwhile, Ce can provide electrons for the Heyrovsky reaction. These effects promoted surface electron migration and thus led to the desorption of adsorbed hydrogen atoms (H ads ) and the decreased diffusion of H ads into the Ni–Cu coatings. The accuracy of the IPZ model fitting results was verified by hydrogen evolution rate experiments during the electroplating process. Hence, Ce salt can effectively inhibit hydrogen permeation and reduce the dehydrogenation annealing time, thereby showing great potential for energy saving and emission reduction in the electroplating industry.

Hydrogen permeation and corrosion behaviour of Cu-coated carbon steel under simulated nuclear waste disposal conditions of the Beishan area have been investigated. The permeation current (with −500 μA·cm −2 charging current) decreased from 3778 to 141 and 47 nA.cm −2 respectively when 5 and 10 µm thick Cu coatings were electrodeposited on the steel. The XRD analysis suggests the formation of CuH during the hydrogen charging treatment, and its subsequent decomposition formed a protective CuOH/Cu 2 O layer on the charging surface when exposed to simulated groundwater for 44 h. No damage to the Cu coating-steel interface was observed in the cross-section analysis.

Abstract In the present study, the area-selective (droplet contact) electrodeposition technique was used to repair damaged areas of the coating by specifying the track. The influence of different current density process parameters on the microstructure and properties of the repair coating were studied. The results show that, after performing local repair of a specified trajectory, the coating exhibits good protective performance. In the 3.5 wt% NaCl test solution, the corrosion resistance current of the repaired coating can reach up to 5.711 × 10 −6 A, which is nearly 100 times higher than that of the damaged coating (5.732 × 10 −4 A). Electron microscope investigations show that the aggregation of crystalline particles becomes more and more obvious with the increasing repair current density. Tafel and Electrochemical Impedance Spectroscopy (EIS) show that the repair process improves the corrosion resistance of the damaged Cu coating. Graphic abstract

The development of advanced materials with superwettability has captured much research interest, because of the increasing environmental concerns and technological requirements. In this work, a titanium mesh coated with copper micro/nanostructures was fabricated via chemical immersion and annealing treatment. The resulting mesh surface consists of titanium and copper oxides with special dendritic and island-like micro-nano binary structures and exhibited remarkable superhydrophobic/superoleophilic property. The superhydrophobic/superoleophilic Ti mesh (SSTM) proved to be efficient for the separation of various water-oil mixtures and exhibited an excellent reusability in repeating separation cycles of water-carbon tetrachloride. Moreover, the SSTM sample displayed great icephobic property including ice-over delay and low ice adhesion. The self-cleaning properties of the SSTM sample were demonstrated using simulated chalk powder that can be easily washed off by injecting water droplets. It also exhibited superior stability in air atmosphere or water over months and great durability under a continuous tap-water flow impacting or abrasion test.

Superhydrophobic metal coatings have been extensively studied in recent years because of their significant potential applications. Unfortunately, most of them lost the original metallic luster due to the micro/nano binary structures. In this paper, a facile method was developed to prepare a superhydrophobic and high-glossy copper coating on aluminum substrates. The bionic lotus leaf surfaces were constructed by electroless plating method and further modified with octadecanethiol. The wettability and gloss could be tuned by the concentration of the precursor. With the increase of CuSO 4 concentration, the surface roughness of the coating raised, thus resulting in increase of contact angle and decrease of glossiness. When the CuSO 4 concentration was 30 mmol/L, the coating exhibited a sub-micro/nano binary structure, in which 20–30 nm protuberances were grown on 300–500 nm mastoids. Such special morphology endowed the coating with superhydrophobic and high-glossy properties, and the coating also showed ultra-low water adhesion and stable dynamic water repellence.

Carbon materials reinforced copper matrix composites with excellent mechanical properties, high thermal conductivity (TC) and suitable coefficient of thermal expansion (CTE) are expected to meet the urgent need for the thermal management materials with structural stability and efficient heat dissipation in civil and military fields. In this work, the tungsten-copper (W-Cu) composite coating was deposited on the graphite flakes (GFs) by the impregnation-reduction and ultrasonic-assisted electroless plating. Meanwhile, the W-Cu coated GFs reinforced Cu matrix composites (GFs(W-Cu)/Cu) were also prepared by the vacuum hot-pressing sintering. Based on the microstructure and surface analysis, the interfacial bonding has changed from the simple mechanical connection to the mechanical-metallurgical synergy. As for the three-point bending and uniaxial tensile tests, the largest in-plane, through-plane flexural strength and tensile strength of the GFs(W-Cu)/Cu composite can achieve the values of 189.6 ± 3.8, 172.3 ± 4.2 and 91.9 ± 2.6 MPa, respectively. Among the GFs(W-Cu)/Cu composites, the ultrahigh in-plane TC and lowest through-plane CTE can reach 929.8 ± 5.0 Wm −1 K −1 and 6.3 ± 0.2 ppmK −1 respectively, and the better thermal response rate can be 0.67 °C·s −1 . In conclusion, an effective way to develop the structural and functional integrated carbon-based thermal management materials can be provided.

Aqueous zinc ion batteries are a promising technology for rechargeable batteries due to their low cost and high safety. However, the interfacial behavior between the zinc anode and the electrolyte often leads to critical issues such as the hydrogen evolution reaction, corrosion, and the formation of zinc dendrites. While protective layers on the zinc anode can improve performance, they may also increase impedance, reduce conductivity, and compromise electric field uniformity. To address these challenges, we developed a novel approach by applying an ultrathin copper (Cu) coating on a zinc anode (Cu@Zn) via a vacuum vapor deposition technique. This method achieves precise nanoscale control over the coating thickness, resulting in a uniform and defect-free protective layer that significantly enhances zinc ion nucleation and effectively suppresses dendrite formation. The symmetric Cu@Zn//Cu@Zn cells cycled over 1200 hours at 5 mA cm−2 and 1 mA h cm−2, surpassing 1000 hours at a high current density of 10 mA cm−2. The full-cell testing conducted at a current density of 1 A g−1 showed a significantly improved cycling stability, with the capacity decay rate reduced from 0.085% to 0.056% per cycle over 1000 charge–discharge cycles. This study presents a viable approach that offers significant potential for advancing battery technology.

Metallic copper is widely used as current collector (CC) for graphite anode of lithium-ion batteries (LIBs) due to its high electrical conductivity and electrochemical stability. However, the large volume density of commercial copper foil (∼8.9 g·cm −3 ) limits the increase of energy density of battery. Here, copper-coated porous polyimide (Cu@PPI) was prepared by vacuum evaporation as collector for the graphite anode. The sandwich structure connects the copper metal on both sides of the collector with excellent electrical conductivity. Compared to commercial Cu foil, Cu@PPI has lighter mass (≤3.9 mg for disc of 12 mm diameter versus 9.9 mg of ∼10 µm Cu foil) and lower volume density (≤3.3 g·cm −3 ). In addition, the porous structure allows of better adhesion of reactive substances and electrochemical properties than pure Cu foils. It is estimated that the energy density of Cu@PPI should be much higher than that of Cu foil. This strategy should be applicable for other current collectors.

In this paper, (3-mercaptopropyl)trimethoxysilane (MPTS)- and copper-coated carbon fiber (M–Cu-CF) was obtained by electroless plating method. The M–Cu-CF was evaluated by FTIR, XRD, TGA, and SEM. It was found that the MPTS and Cu were coated on the fiber surface successfully. The M–Cu-CF was utilized as a conductive filler in silicone rubber (SR) for thermal and electrical conductivity applications and exhibited good dispersion and compatibility with the matrix. The effect of M–Cu-CF content on the thermal conductivity and volume resistivity of silicone rubber composites was investigated. The results showed that the thermal conductivity of the M–Cu-CF/SR composites reached 1.99 W (m K) −1 with only 4.0 wt% filler loading, approximately 2.10 times higher than that of raw-CF/SR composites at the same loading. And with the increase of M–Cu-CF loading, the least volume resistivity of M–Cu-CF/SR composites was 3.5 × 10 3 Ω cm.

Addressing the significant obstacles of volume expansion and inadequate electronic conductivity in silicon-based anode materials during lithiation is crucial for achieving a long durable life in lithium-ion batteries. Herein, a high-strength copper-based metal shell is coated in situ onto silicon materials through a chemical combination of copper citrate and Si–H bonds and subsequent heat treatment. The formed Cu and Cu3Si shell effectively mitigates the mechanical stress induced by volume expansion during lithiation, strengthens the connection with the copper substrate, and facilitates electron transfer and Li+ diffusion kinetics. Consequently, the composite exhibits a reversible specific capacity of 1359 mA h g–1 at 0.5 A g–1 and maintains a specific capacity of 837 mA h g–1 and an 83.5% capacity retention after 400 cycles at 1 A g–1, surpassing similar reports on electrochemical stability. This facile copper plating technique on silicon surfaces may be used to prepare high-performance silicon-based anodes or functional composites in other fields.
