Inspired by marine mussel adhesive proteins, polymers with catechol side groups have been extensively explored in industrial and academic research. Here, Pluronic L-31 alcoholate ions were used as the initiator to prepare a series of polypeptide–Pluronic–polypeptide triblock copolymers via ring-opening polymerization of l-DOPA-N-carboxyanhydride (DOPA-NCA), l-arginine-NCA (Arg-NCA), l-cysteine-NCA (Cys-NCA), and ε-N-acryloyl lysine-NCA (Ac-Lys-NCA). These copolymers demonstrated good biodegradability, biocompatibility, and thermoresponsive properties. Adhesion tests using porcine skin and bone as adherends demonstrated lap-shear adhesion strengths up to 106 kPa and tensile adhesion strengths up to 675 kPa. The antibleeding activity and tissue adhesive ability were evaluated using a rat model. These polypeptide–Pluronic copolymer glues showed superior hemostatic properties and superior effects in wound healing and osteotomy gaps. Complete healing of skin incisions and remodeling of osteotomy gaps were observed in all rats after 14 and 60 days, respectively. These copolymers have potential uses as tissue adhesives, antibleeding, and tissue engineering materials.

A high-temperature conductive silver slurry containing lead-free ZnO-B2O3-SiO2 glass for metallization of ceramic MgTiO3 substrate has been prepared. The ZnO-B2O3-SiO2 glass was obtained by high-temperature melting and cold extraction with a transition temperature (Tg) of 579 °C and thermal stability (∆T) of 105 °C as an inorganic bonding phase of high-temperature conductive silver paste. Then, silver paste with different glass powder content was sintered on ceramic MgTiO3 substrate between 730 °C and 930 °C in increments of 50 °C. Characterization of the prepared materials revealed that their resistivity increases with the increase in glass powder content and decreases with the increase in sintering temperature. Sintering temperature and glass content have significant effects on the resistivity and adhesion of the thick silver film. When the silver paste with a glass content of 1.1 wt% was sintered at 830 °C for 10 min, the resulting thick silver film had a low resistivity of 1.81 μΩ·cm (1.65 μΩ·cm for silver) and a good adhesive strength of 39.4 N mm−2. During the sintering process, the glass material melts and wets the silver powder, which promotes the sintering of the silver powder to form a dense network structure and improves the electrical conductivity of the silver film. In addition, the formation of ZnTiO3 by chemical reactions between the glass and the substrate was observed, which dramatically improved the bonding strength of the silver film. Therefore, lead-free silver paste containing ZnO-B2O3-SiO2 glass powder and MgTiO3 ceramics has broad development prospects in ceramic filters.

The metallization of glass with high density and fine spacing possesses promising application in advanced package in 5 G. However, the adhesion strength between the copper and the smooth glass is still limited. In this paper, a feasible method is developed to prepare ZnO coating on the glass surface which served as an adhesive layer to provide a good anchors of copper layer by electroless copper plating. The results proved the adhesion strength of the copper layer is as high as 5B by grid adhesion test. Furthermore, diethoxy-methyl-(3, 3, 3-trifluoro-propyl)-silane was used to create an optional hydrophobic surface to accomplish a selective electroless copper plating pattern. The electroless copper plating is non-toxic, convenient, low economic cost and reliable and it is expected to realize promising application in system-in-package in the future.

To limit the use of petrochemical resources in the context of the energy crisis, it is critical to produce sustainable thermoplastic adhesives. However, it is still difficult for biomass-based hot-melt adhesives to attain superior adhesion strength and recyclability. An intriguing option for sustainable polyester hot-melt adhesives is provided by vanillin, an aromatic lignin derivative with a structure of many oxygen-containing functional groups. Charged negative oxygen-containing functional groups can easily interact with positively charged substrates such as metals, and copolyesters containing vanillin-derived monomers can be used as hot-melt adhesives to achieve a favorable balance between substrate adhesion and cohesion of the polyester glue layer. Here, we designed and modified the lignin-derived aromatic chemical vanillin for copolymerization with 1,4-butanediol (BDO), dimethyl terephthalate (DMT), and diethylene glycol (DEG) to obtain partial biobased copolyesters. The produced copolyesters exhibited excellent adhesion to diverse metal substrates because the monomer generated from vanillin contained a range of oxygen-containing groups including methoxy, hydroxyl, carboxyl groups, and ether bonds. With single-lap shear strengths of 10.6, 14.4, and 15.1 MPa for aluminum, brass, and iron, respectively, the copolyester with 30% vanillin-derived monomer content demonstrated outstanding adhesion. The resultant copolyesters can be recycled by dissolving them in a particular solvent at room temperature and exhibiting good resistance to heat, acids, and alkalis. Additionally, we evaluated the potential interaction of naturally oxygenated biomass derivatives with metal atoms using density functional theory (DFT), assessed the rational material design, and explained how exceptional adhesion properties are achieved.

Polycarbonate-acrylonitrile-butadiene-styrene (PC-ABS) has been treated with an aqueous solution of N -methylpyrrolidone (NMP) and ethanol (C 2 H 5 OH) under conditions that achieve a controlled level of polymer swelling. In addition, the micro-etching effect of alkaline potassium permanganate on PC-ABS was investigated using a low environmental impact binary micro-etching system. The effect of NaOH concentration, etching time, and temperature on surface roughness, morphology, wettability, and PC-ABS adhesion strength has been examined. The PC-ABS surface characteristics were analyzed using field emission scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform-infrared (FT-IR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The results have demonstrated that the surface morphology was altered after micro-etching, with an increase in surface roughness ( R a ) from 9.69 to 316 nm. In addition, the contact angle decreased from 92.2° to 30.1°, and the adhesion strength increased to 0.88 kN/m. The findings of this study have established an effective micro-etching process using alkaline potassium permanganate that enhances the wettability, surface roughness, and adhesion strength of the PC-ABS copolymer.

Polar regions hold significant potential for energy and resource development, but extreme temperatures and persistent ice pose challenges to commercial shipping, resource exploration, and scientific research. Here, a super-slippery oleogel ice-phobic coating (CP_U80@L-Ppy) with ultra-low temperature applicability is developed using expanded lamellar graphite networks and temperature-controlled deformed microspheres modified with linear polypyrrole. The ice adhesion strength at −30 °C is reduced to ≈ 3.76 kPa in the horizontal shear mode and remains below 10 kPa after 231 icing/shear detachment cycles. At ultra-low temperatures (−100–−70 °C), the ice adhesion strength stays below 30 kPa due to the vertical modulus mismatch between the ice and coating, along with the tangential modulus mismatch between the surface components. The coating also exhibits photo- and electro-responsive anti-icing/ice-phobic functionalities, broadening its potential for all-weather applications. Under “1 sun” irradiation at −30 °C, rapid defrosting (1 min) and ice detachment (2.8 min) are achieved. Additionally, electro-responsive defrosting and ice detachment periods of 1.4 and 2.6 min, respectively, are obtained using only two standard batteries in series (3.5 V) at −15 °C, demonstrating high energy efficiency. This work offers a promising strategy for developing efficient ice-phobic technologies suited to ultra-cold environments, with practical potential for polar applications.

In this study, an environmentally friendly cerium (Ce) conversion coating was deposited onto the surface of aluminum (Al) foil for preparing the packaging material of lithium-ion batteries, and its morphology, composition, and formation mechanisms were investigated using scanning electron microscopy (SEM), atomic force microscopy (AFM), energy-dispersive spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). The packaging material consisting of six layers was prepared by hot pressing using casting polypropylene (CPP) as the inner layer and maleic anhydride (MAH) grafted polypropylene (mPP) as the inner adhesive. The adhesion properties of untreated and Ce-treated Al foils were characterized by T-peeling test. The results show that Ce conversion coating is mainly composed of cerium dioxide (CeO 2 ) and cerium sesquioxide (Ce 2 O 3 ), and Ce treatment leads to a significant increase in the adhesive strength between Al foil and mPP.

Polytetrafluoroethylene (PTFE) is widely used as a polymer substrate for high-frequency microwave copper cladding due to its low dielectric loss and high stability. However, its inherently low thermal conductivity requires the use of high-content fillers, which complicates efforts to balance thermal conductivity, adhesion strength, and dielectric loss of the composite materials. Herein, we introduce PTFE composites with a hybrid filler network, where the synergistic alignment and interaction of two-dimensional hexagonal boron nitride (h-BN) and granular β-silicon nitride (Si 3 N 4 ) forms interconnected pathways in the vertical direction. The spatial arrangement of large-sized h-BN can bridge and shorten the thermal conduction path within the Si 3 N 4 network, forming robust vertical thermal pathways, achieving an out-of-plane thermal conductivity of 1.6 W/m K. Additionally, the complementary properties of h-BN and Si 3 N 4 enhance the overall performance. Si 3 N 4 reduces stress concentration, improving adhesion strength, while h-BN's wide bandgap and weak polarity help minimize dielectric loss. This combination results in a peeling strength of 1.3 N/mm with copper foil and a remarkably low dielectric loss (<0.0011) at 10 GHz. The ultimate PTFE composite ensures reliable, stable, and secure signal transmission in high-frequency communication devices, making it a highly promising material for the electronics sector.

One of the major challenges during the development of low-permeability sandstone reservoirs is the interaction between the oil and rock, which makes it difficult to displace the oil in the nanoscale pores of the formation rock. This study investigates the interaction between typical crude oil components, such as chain alkyl, sulfonic acid group, and carboxyl group, and representative sandstone monominerals, including quartz, albite, and potassium feldspar in the aqueous phase with different salinities by using the nanomechanical method. The maximum adhesion strength measured in this study is 768.75 nN μm–2, which is the adhesion strength between the carboxyl group and quartz in simulated formation water, and it is 9.2 times higher than that of the sulfonic acid group and albite in deionized water. Experimental results show that the high concentration of cations in the formation water enhances the adhesion strength between the polar components of crude oil and sandstone monominerals, resulting in strong attractive forces. Furthermore, it is found that the dominant components responsible for this strong interaction are the carboxyl group and quartz. In addition, the results show that the intensity and range of adhesion strength caused by the high-valent cations, such as Mg2+, Ca2+, and Al3+, are larger than those of the low-valent cations, such as Na+ and K+, and increase with increasing ion concentration. By accurately quantifying the interaction between typical components of crude oil and sandstone monominerals, this study reveals the adhesion mechanism of crude oil in low-permeability sandstone reservoirs, which provides a theoretical basis for the efficient displacement of oil.

A biodegradable tissue adhesive was prepared from dextran urethane (Dex-U), which could be photocrosslinked under the UV irradiation, and steadily adhere to surface of gelatin and mouse skin, which simulate the human tissue. The structures of above Dex-U were characterized by FTIR, 1 H NMR spectroscopy and XRD. The adhesion properties of result products was evaluated by lap-shear test and burst pressure test. The highest adhesion strength and burst pressure could reach to 2.99 MPa and 35 mmHg, respectively. The photopolymerization process of Dex-U was monitored by real time infrared spectroscopy (RTIR), and the surface tension of Dex-U solution was tested by du Nouy Ring method. The cytotoxicity of Dex-U also was evaluated. The relationship between all above properties and degree of substitution of Dex-U was assessed. The adhesive strength of Dex-U is significantly higher than that of fibrin glue. The obtained products present the potential to serve as tissue adhesive in medical area in the future.

Waterborne polyurethane elastomer (WPU) has been widely used as a glue, but it still has some drawbacks, including a long cure time and weak adhesive force. In order to overcome these drawbacks, a new composite [PU/ferric ion complexation (Fe/PU)] with high adhesive strength was successfully prepared using ferric ion (Fe 3+ ) as a complexing agent. Fourier transform infrared spectroscopy, differential scanning calorimetry, dynamic mechanical analysis, and tensile testing were used to characterize the chemical structure and mechanical properties of the as-obtained composites. Introduction of the ferric ion induces a certain degree of microphase separation, resulting in better mechanical strength and interfacial adhesion. The mechanical properties of the PU composite with ferric ions are higher than that of pure PU. The adhesive strength of the 25%-Fe/PU composite is 32.46 ± 3.1 MPa, exhibiting superior adhesive strength. The tensile strength was enhanced 34%, and the elongation was enhanced 23.6% compared to pure PU. Furthermore, the Fe/PU composite, coordinated with ferric ions, exhibits an enhanced storage modulus and reduced loss coefficient compared to PU. We can foresee that Fe/PU composites will play an important role in the building and engineering areas. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018 , 135 , 46069.

The risk of freezing on exposed surfaces has consistently posed a challenge to both safety and economy. Bionic orientation structure is significant in reducing locomotion resistance. In this work, a stress-localized material is prepared by coating the room temperature vulcanized silicone rubber (RTV) on the fish skin-like structure surface. The influence of the coating thickness and structural parameters of the fish skin on its ice-repellent and tribological properties is investigated at low temperatures. The results demonstrate that the small hook-like spine structure covered with a 1 mm thickness of RTV exhibits the lowest ice adhesion strength in the positive direction. This is because the stress localization phenomenon is easily triggered by the small hook-like spines. Furthermore, the lowest friction coefficient in the positive direction is achieved, which can serve to reduce friction and provide directional lubrication. The molecular dynamics results demonstrate that the strong interaction between the ice and RTV molecules at lower temperatures contributes to the high ice adhesion strength. The results of this work make the stress-localized material with oriented structures a promising candidate for specific de-icing and tribological applications.
