Synthesis of polymeric superhydrophobic coatings of nickel stearate for excellent corrosion resistance, self-cleaning, and photodegradation

Superhydrophobic coatings (SHCs) have been widely reported for various applications; however, the practical applications of SHCs have been restricted by recurrent preparation methods, complex equipment, and low mechanical robustness. The development of a simple, low-cost, and effective superhydrophobic coating remains a challenge. Here, we reported a simple way to fabricate the SHC by using fluoropolymeric suspension of nickel stearate nanoparticles (Ni-St-NPs) on the copper and other substrates. The surface of copper coated by SHC showed a static contact angle of 161 ± 1º and a sliding angle of 2º. Scanning electron microscopy with energy-dispersive spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Fourier transform infrared spectrometer were used to determine the surface morphology, elemental content, crystal structures, chemical bonding, and structure of the SHCs. The fluoropolymeric coating of Ni-St-NPs showed excellent anti-corrosion and self-cleaning with mechanical durability and stability. Photodegradation of methylene blue (MB) and rhodamine B (RhB) dyes were done at 25 °C and obtained the degradation efficiency of 99 % and 98.1 %, respectively. The existence of self-cleaning, mechanical durability, and photocatalytic properties makes the fluoropolymer coating of nickel stearate a very promising superhydrophobic coating material for multifunctional applications.

Lightweight polyimide composite foams with anisotropic hierarchical pore structure for enhanced mechanical, flame retardancy and thermal insulation purposes

In this study, lightweight polyimide foam (PIF) with anisotropic pore structure were fabricated by adopting microwave-assisted foaming technique. Afterward, lightweight PIF/PI aerogel/silica aerogel (PIF/PIA/SiA) composite foams with anisotropic hierarchical pore structures was prepared by impregnation and directional freeze-drying method. The directional growth of foam pores and ice crystals endowed PIF/PIA/SiA composite foams with anisotropic skeleton structures and hierarchical porous filling structures, leading to anisotropic mechanical and thermal insulation performances. PIF/PIA/SiA composite foams presented mechanical robustness in vertical direction and mechanical flexibility in horizontal direction due to its unique pore structure. In addition, PIF/PIA/SiA composite foams showed outstanding thermal stability and flame retardancy, suggesting a promising application in the field of high temperature fire protection. The PIF/PIA/SiA composite foams exhibited superior thermal insulation performance with thermal conductivities ranging from 0.0253 to 0.0523 W/(m·K) between 25 and 300 °C. Therefore, a facile strategy was developed to fabricate PIF-based composite foams for mechanical, flame retardancy and thermal insulation applications in high-end engineering fields.

Specific applications in oculoplastic and orbital surgeries, hydrogel applications in ocular therapeutics, and polymeric drug delivery systems for a range of ophthalmic conditions were reviewed. We also anticipate future directions and identify challenges in the field, advocating for a collaborative approach between material science and ophthalmic practice to foster innovative, patient-focused treatments.

Effects of Electrolyte Solvent Composition on Solid Electrolyte Interphase Properties in Lithium Metal Batteries: Focusing on Ethylene Carbonate to Ethyl Methyl Carbonate Ratios

This study investigated the influence of variations in the mixing ratio of ethylene carbonate (EC) to ethyl methyl carbonate (EMC) on the composition and effectiveness of the solid electrolyte interphase (SEI) in lithium-metal batteries. The SEI is crucial for battery performance, as it prevents continuous electrolyte decomposition and inhibits the growth of lithium dendrites, which can cause internal short circuits leading to battery failure. Although the properties of the SEI largely depend on the electrolyte solvent, the influence of the EC:EMC ratio on SEI properties has not yet been elucidated. Through electrochemical testing, ionic conductivity measurements, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy, the formation of Li2CO3, LiF, and organolithium compounds on lithium surfaces was systematically analyzed. This study demonstrated that the EC:EMC ratio significantly affected the SEI structure, primarily owing to the promotion of the formation of a denser SEI layer. Specifically, the ratios of 1:1 and 1:3 facilitated a uniform distribution and prevalence of Li2CO3 and LiF throughout the SEI, thereby affecting cell performance. Thus, precise control of the EC:EMC ratio is essential for enhancing the mechanical robustness and electrochemical stability of the SEI, thereby providing valuable insights into the factors that either enhance or impede effective SEI formation.

Hierarchically‐Structured and Mechanically‐Robust Hydrogel Electrolytes for Flexible Zinc‐Iodine Batteries

AbstractHydrogel electrolytes have been widely explored in aqueous zinc‐iodine batteries (AZIBs), in light of their intrinsic strong water‐retention capability and superior flexibility of hydrogel network. However, hydrogel‐based AZIBs are still facing challenges due to the inferior ionic conductivity, dendrite formation, and corresponding fatigue‐induced damage. Herein, a hydrogel electrolyte is designed and engineered with preferentially aligned porous structures, where Zn2+ can promptly transport along the pores. AZIBs fabricated from the hydrogel electrolyte exhibited distinct cycling stability over 1,000 h (500 cycles) at 0.5 mA cm−2. Moreover, in light of the substantially improved mechanical robustness, the hydrogel electrolyte network remained intact over a 27,000‐cycle charging/discharging test at 5 A g−1, with a slight change in capacity, surpassing most previously reported AZIBs. Such kind of hydrogel electrolyte‐based AZIBs can be further explored as the flexible power system for wearable devices, enabling significantly accelerated wound healing through electrical stimulation over the epidermal wounds. This work sheds light on hydrogel electrolytes design for long‐life aqueous zinc‐based batteries, with great potential as power systems for wearable and implantable devices.

Fabrication framework for metal supported solid oxide cells via tape casting

Among the different solid oxide cells (SOCs) designs, metal supported SOCs (MSOCs) offer important advantages such as enhanced mechanical robustness, improved thermal resilience and lower material costs. The conventional tape casting method, which is used for the commercial multilayer ceramic technology, is also attractive for the fabrication of MSOCs due to its inherent scalability and cost-efficient fabrication methodology while offering a reliable product without compromising critical microstructural aspects and electrochemical performance during operation.This study is aimed at addressing the main challenges in the fabrication of MSOCs using tape casting, to provide a robust framework for the fabrication parameters, allowing the technology to advance to a more mature stage. It was shown that the dispersion of the powder particles and the physical and chemical characteristics of the binder are found to play a crucial role in obtaining defect free MSOCs and are discussed in detail. Different architectural designs of the cells (asymmetric and symmetric) and electrode configurations (ceramic and metal-ceramic composites) are studied, highlighting their strengths and challenges. The framework established within this work allowed to fabricate, reproduce and test MSOC that exhibited electrochemical performance comparable to state-of-the-art solid oxide cells (electrolysis current density of 0.6 A/cm2 at 1.3 V at 700oC, 50 % steam in H2 at fuel side and air at the oxygen side).

Customized Electronic Modulations of Transition Metal Chalcogenide Electrodes Via Heterointerfacing/High‐Valence Doping Toward High‐Performance Water Electrolysis with Ampere‐Level Current Density

AbstractElectrochemical water splitting offers an advancing approach to producing highly pure hydrogen and oxygen, motivated by the prevalence of a low‐carbon economy and the goal of a sustainable future. The customized modulation of electronic structures enables the electrocatalyst to directionally promote hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), which is a promising shortcut to overall water splitting (OWS). Herein, 3D homologous WSeS/CoSeS heterojunction nanoarrays (WSeS/CoSeS NAs) and W‐doped CoSeS nanoarrays (W‐CoSeS NAs) are investigated. Abundant heterointerfaces within WSeS/CoSeS NAs facilitate HER kinetics, boosting mass diffusivity, and increasing carrier separation and transfer process. High‐valence W6+ doping into CoSeS prevents phase separation and stabilizes Co sites by charge offset effect, leading to enhanced OER. Consequently, the WSeS/CoSeS NAs and W‐CoSeS NAs reach 10 mA cm−2 at an overpotential of 43.8 and 233.3 mV in 1.0 m KOH electrolyte for HER and OER, respectively. Moreover, when asymmetrically engaged as an electrolyzer, this configuration exhibits extraordinary electrocatalytic performances (cell voltage of 1.51 V at 10 mA cm−2) with satisfying stability and mechanical robustness (over 1000 h at 1000 mA cm−2). The modulation and manufacture of reaction‐property‐oriented materials are experimentally and theoretically validated potential, illuminating the light of inspiration for multiple applications.

Development of a mechanically robust silicon-based cross-linking polymer for the sustainable marine antifouling coatings

Silicone-based fouling release coatings (FRCs) have shown great promise as an environmentally friendly antifouling technology, while inferior mechanical properties and insufficient substrate adhesion have hindered their further application. We focused on enhancing the mechanical robustness of silicone-based coating through the synergistic effects of hydrogen bonding, π-π aromatic interaction and covalent bonding. The resulting silicone-based coating displayed a low surface energy of 23 mJ/m2 and improved mechanical strength and substrate adhesion, offering values up to 6.4 MPa (9.1 times higher) and 2.87 MPa (25.7 times higher), respectively. Additionally, the modified coating demonstrated a tear strength of 9.8 kN/m and mass loss only about 30 mg after enduring 10,000 wear cycles. Alkoxysilane-functionalized polyethylene glycol and quaternary ammonium salt were grafted into the cross-linking structure to make them anchored to the networks and migrated to the surface layer in seawater without releasing. The coating provided 99.1% antibacterial efficiency and effective antidiatom performance (≤ 11.2 cell/mm2). After a 12-month marine field test, the developed film showed only 20% micro bio-fouling compared to 100% fouling coverage on the PDMS surface. By combining improved mechanical properties with antifouling characteristics, this new multifunctional silicone-based FRC exhibits tremendous potential for sustainable marine antifouling coating application.

Dual dynamic H-bonds crosslink side chains support a robust polysiloxane elastomer and its self-repairing and recycling properties

Owning excellent mechanical properties and mild repair conditions simultaneously has always been a paradox in the field of self-healing polysiloxane elastomer research. In this work, a robust polysiloxane elastomer with autonomic self-repairing at r. t. and recyclable properties was firstly designed and synthesized. The double strong H-bonds ensure the strength of the elastomer, while the urea bond with relatively weak bond energy also acts as a sacrifice bond to dissipate energy and further bolster the mechanical properties. Meanwhile the double dynamic bonds located in the side chain with stronger molecular activity ability help to get good self-healing performance. Additionally, the material that can be recycled by crushing/remolding and dissolving/remolding methods without compromising their mechanical robustness and self-repairing properties is environmentally friendly.

4D Printing of Magneto‐Thermo‐Responsive PLA/PMMA/Fe3O4 Nanocomposites with Superior Shape Memory and Remote Actuation

AbstractThis study presents the development and 4D printing of magnetic shape memory polymers (MSMPs) utilizing a composite of polylactic acid (PLA), polymethyl methacrylate (PMMA), and Fe3O4 nanoparticles. The dynamic mechanical analysis reveals that the integration of Fe3O4 maintains the broad thermal transition without significantly affecting α‐relaxation time, indicating high compatibility and homogeneous distribution of the nanoparticles within the polymer matrix. Field emission scanning electron microscopy further confirms the high compatibility of PLA and PMMA phases as well as uniform dispersion of Fe3O4 nanoparticles, essential for the effective transfer of heat during the shape memory process. Significantly, the incorporation of magnetic nanoparticles enables remote actuation capabilities, presenting a substantial advancement for biomedical applications. 4D‐printed MSMP nanocomposites exhibit exceptional mechanical properties and rapid, efficient shape memory responses under both inductive and direct heating stimuli, achieving 100% shape fixity and 100% recovery within ≈85 s. They are proposed as promising candidates for biomedical implants, specifically for minimally invasive implantation of bone scaffolds, due to their rapid remote actuation, biocompatibility, and mechanical robustness. This research not only demonstrates the 4D printability of high‐performance MSMPs but also introduces new possibilities for the application of MSMPs in regenerative medicine.

Influences of Heat Treatment, Particle Arrangement, and Binder Addition on the Mechanical Robustness of Structurally Colored Coatings Formed with Monodisperse SiO2 Spheres

This article highlights the critical factors influencing the mechanical robustness of structurally colored coatings formed as arrays of monodisperse SiO2 particles. Various types of coatings can be fabricated using electrophoretic deposition (EPD) techniques. Anodic EPD generates coatings with colloidal crystalline structures, iridescent structural color, and noteworthy mechanical robustness owing to interparticle necking during heat treatment, even in the absence of binder additives. Conversely, coatings prepared via cathodic EPD exhibit noniridescent structural color and colloidal amorphous structure, with only marginally improved mechanical robustness after high‐temperature treatment. However, when Mg(OH)2 is codeposited during EPD in the coating, the resultant film exhibits strong adhesion between particles and the substrate—as evidenced by minimal peeling from the substrate even after ultrasonication for 6 h—owing to the binding effect of MgO, which is converted from Mg(OH)2 via heat treatment. The robustness of the film is not dictated by the size of the SiO2 particles, suggesting that this approach can be applied to structurally colored coatings of various colors. Consequently, the results suggest that EPD with the addition of a binder and heat treatment can be used to fabricate particle‐array‐type coatings with extremely high mechanical robustness.

On the design of lignin reinforced acrylic acid/hyaluronic acid adhesive hydrogels with conductive PEDOT:HA nanoparticles

Processing natural bamboo into white bamboo through photocatalyzed lignin oxidation

Scalable and highly efficient bamboo whitening remains a great challenge. Herein, an effective bamboo whitening strategy is proposed based on photocatalyzed oxidation, which involves H2O2 infiltration and UV illumination. The as-prepared white bamboo well maintains the nature structure of natural bamboo and demonstrates high whiteness and superior mechanical properties. The absorbance value is significantly decreased to 3.5 and the transmittance is increased to 0.04 % in UV–visible wavelength range due to the removal of light-absorbing chromospheres of lignin, resulting in a high whiteness when the UV illumination time is 8 h. In addition, the white bamboo displays a high tensile strength of 30 MPa and a high flexural strength of 36 MPa due to the well-preserved lignin units (lignin preservation is about 89 %). XRD patterns and analysis show that photocatalyzed oxidation has no effect on the crystal parameters of cellulose. Compared with the traditional bamboo whitening technology, our photocatalyzed oxidation strategy demonstrates significant advantage including chemical and time conservation, high efficiency, environment friendliness, and mechanical robustness. This highly efficient and environmentally friendly photocatalyzed oxidation strategy for the fabrication of white bamboo may pave the way of bamboo-based energy-efficient structural materials for engineering application.

Advances in Stretchable Organic Photovoltaics: Flexible Transparent Electrodes and Deformable Active Layer Design.

Stretchable organic photovoltaics (OPVs) have attracted significant attention as promising power sources for wearable electronic systems owing to their superior robustness under repetitive tensile strains and their good compatibility. However, reconciling a high power-conversion efficiency and a reasonable flexibility is a tremendous challenge. In addition, the development of stretchable OPVs must be accelerated to satisfy the increasing requirements of niche markets for mechanical robustness. Stretchable OPV devices can be classified as either structurally or intrinsically stretchable. This work reviews recent advances in stretchable OPVs, including the design of mechanically robust transparent electrodes, photovoltaic materials, and devices. Initially, an overview of the characteristics and recent research progress in the areas of structurally and intrinsically stretchable OPVs is provided. Subsequently, research into flexible and stretchable transparent electrodes that directly affect the performances of stretchable OPVs is summarized and analyzed. Overall, this review aims to provide an in-depth understanding of the intrinsic properties of highly efficient and deformable active materials, while also emphasizing advanced strategies for simultaneously improving the photovoltaic performance and mechanical flexibility of the active layer, including material design, multi-component settings, and structural optimization.

Intrinsically stretchable organic photovoltaics by redistributing strain to PEDOT:PSS with enhanced stretchability and interfacial adhesion

Intrinsically stretchable organic photovoltaics have emerged as a prominent candidate for the next-generation wearable power generators regarding their structural design flexibility, omnidirectional stretchability, and in-plane deformability. However, formulating strategies to fabricate intrinsically stretchable organic photovoltaics that exhibit mechanical robustness under both repetitive strain cycles and high tensile strains remains challenging. Herein, we demonstrate high-performance intrinsically stretchable organic photovoltaics with an initial power conversion efficiency of 14.2%, exceptional stretchability (80% of the initial power conversion efficiency maintained at 52% tensile strain), and cyclic mechanical durability (95% of the initial power conversion efficiency retained after 100 strain cycles at 10%). The stretchability is primarily realised by delocalising and redistributing the strain in the active layer to a highly stretchable PEDOT:PSS electrode developed with a straightforward incorporation of ION E, which simultaneously enhances the stretchability of PEDOT:PSS itself and meanwhile reinforces the interfacial adhesion with the polyurethane substrate. Both enhancements are pivotal factors ensuring the excellent mechanical durability of the PEDOT:PSS electrode, which further effectively delays the crack initiation and propagation in the top active layer, and enables the limited performance degradation under high tensile strains and repetitive strain cycles.

Ultra-Flexible microwave absorber of PEDOT:PSS/Melamine composite film with wide tunable frequency controlled by Self-Strain sensing

The exploration of smart microwave (MW) absorption materials with excellent mechanical properties and wide frequency tuning ability is challenging work. Herein, an ultra-flexible MW absorber with wide frequency modulation by itself strain sensing has been successfully constructed, which is realized by introducing doped conductive poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate) (PEDOT:PSS) with dimethyl sulfoxide (DMSO) into three-dimensional melamine foam (MF) network. The formed MF/P-D20 composite itself is a piezoresistive sensor with a high sensitivity. Most importantly, it is found that the absorption frequency band of the MF/P-D20 composite film can be controllably and reversibly modulated in a wide frequency range from S to Ku bands by changing the compression strain monitored by the value of ΔR/R0. Furthermore, theoretical simulations and experimental findings confirm that the variations of pore shape and size after compression serve as a crucial factor responsible for shifting the enhanced electron flux density and MW loss to higher frequency, which consequently induces the shift of impedance matching and sequent MW absorption to higher frequency. The MW absorber also shows excellent properties of mechanical robustness, thermal insulation, electro-thermal conversion and retardant. This study provides insights into the smart and reversible control of MW absorption properties and paves the way for tuning MW absorption frequency in wide frequency.

Mechanical and thermodynamic stability of the high melting point and hardness metallic anti-perovskite Cr[formula omitted]GeN

Utilizing density functional and perturbation theory, combined with ab initio molecular dynamics methods, we investigate the phonon and vibrational properties, mechanical and thermodynamic characteristics, as well as melting points of the tetragonal and cubic phases of anti-perovskite nitride Cr3GeN. Our findings demonstrate that the cubic phase is stable at high temperatures but exhibits the softening of the optical phonon mode at the Brillouin zone center at low temperatures, thereby transforming into the tetragonal phase. Both the tetragonal and cubic phases exhibit mechanical robustness and satisfy the conditions for mechanical stability. As a metallic compound, the anti-perovskite Cr3GeN additionally possesses high hardness and melting point, thus stimulating high hardness and temperature applications.

Formulation and evaluation of ivermectin-loaded dissolving microarray patches for rosacea disease

PurposeThis investigation aims to develop and characterise dissolving microarray patches (MAPs) loaded with ivermectin (IVM) for rosacea therapy.MethodsTween® 80 and Soluplus® were evaluated to enhance the water solubility of IVM powder. Three dissolving MAPs were fabricated using a two-layer casting method, pure IVM-loaded (F1), IVM-Tween® 80 (F2), and IVM-Soluplus® (F3) loaded patches. Formulations were evaluated for drug content, in vitro and ex vivo mechanical performances, ex vivo skin dissolution time, dermatokinetics, in vitro biocompatibility and activity against rosacea.ResultsIVM solubility in water was improved with surfactants, reaching 1206.42 ± 53.78 and 130.78 ± 12.78 µg/mL in Tween® 80 and Soluplus® solutions, respectively. The MAPs, featuring bubble-free, perfectly shaped pyramidal needles of approximately 800 μm, exhibited considerably higher IVM content in F2 and F3 than in F1 (2.31 ± 0.26 mg for F1, 3.58 ± 0.15 mg for F2, and 3.19 ± 0.22 mg for F3). All formulations demonstrated mechanical robustness and penetrated the skin to a depth of 650 μm. The highest IVM deposition in the skin at 24 h was achieved by F2, selected as the lead formulation (F1 = 1456.35 ± 266.90 µg; F2 = 2165.24 ± 130.13 µg; F3 = 1684.74 ± 212.09 µg). Furthermore, F2 and F3 provided faster IVM deposition, most likely due to the quicker dissolution rate of microneedles in the skin. F2 proved biocompatible to skin cells in vitro and effectively inhibited the inflammatory cascade associated with rosacea diseases.ConclusionThis study encourages further investigation into IVM-loaded dissolving MAPs formulated with Tween® 80 for rosacea therapy.

Fabrication of fully bio-based malleable thermoset derived from cellulose, furfural and plant oil for advanced capacitive sensor

Fabrication of sustainable bio-based malleable thermosets (BMTs) with excellent mechanical properties and reprocessing ability for applications in electronic devices has attracted more and more attention but remains significant challenges. Herein, the BMTs with excellent mechanical robustness and reprocessing ability were fabricated via integrating with radical polymerization and Schiff-base chemistry, and employed as the flexible substrate to prepare the capacitive sensor. To prepare the BMTs, an elastic bio-copolymer derived from plant oil and 5-hydroxymethylfurfural was first synthesized, and then used to fabricate the dynamic crosslinked BMTs through Schiff-base chemistry with the amino-modified cellulose and polyether amine. The synergistic effect of rigid cellulose backbone and the construction of dynamic covalent crosslinking network not only achieved high tensile strength (8.61 MPa) and toughness (3.77 MJ/m3) but also endowed the BMTs with excellent reprocessing ability with high mechanical toughness recovery efficiency of 104.8 %. More importantly, the BMTs were used as substrates to fabricate the capacitive sensor through the CO2-laser irradiation technique. The resultant capacitive sensor displayed excellent and sensitive humidity sensing performance, which allowed it to be successfully applied in human health monitoring. This work paved a promising way for the preparation of mechanical robustness malleable bio-thermosets for electronic devices.
