The interface between the membrane and catalytic layer (CL) is pivotal for enhancing catalyst utilization performance of proton exchange fuel cells (PEMFCs) . However, studies in HT-PEMFCs have been rarely reported. In this study, first time, a one-step plasma etching technique was utilized to prepare poly[2,2′-(p-oxidiphenylene)-5,5′-benzimidazole] (OPBI) with nanoscale rough surface, achieving an optimized HT-PEM/CL interface. Plasma significantly increased membrane's surface roughness from 2.12 18.7 nm. width–depth ratio etched its compatibility size particles affect cell. As result, compared electrode assembly (MEA) using unmodified OPBI, 900 s OPBI-MEA (900 S-OPBI-MEA) exhibits 127.97% increase electrochemically active area (ECSA) 78.7% improvement peak power density, reaching 692.8 mW cm–2. These findings underscore significant promise employing on engineering advanced interfaces.

Preparation of a Superhydrophobic Coating on Carbon Fiber Board and Study of Its Dust Resistance and Anti-icing Properties

ACS Applied Engineering Materials, Год журнала: 2025, Номер 3(3), С. 761 - 770

Опубликована: Март 5, 2025

To address the poor water resistance and dust susceptibility of carbon fiber board, a simple efficient spraying method was used to prepare superhydrophobic coating on board that resistant ice. First, hydrolyzed solution KH550 applied cured board. Then, prepared by mixing silicone rubber (XC-107) with γ-aminopropyltriethoxysilane (KH550) in ethyl acetate. This divided into three glass beakers. The first beaker kept original unchanged. Nanometer silica (Nano-SiO2) introduced second beaker, while acetate added dilute third beaker. Finally, solutions were sequentially sprayed onto surface according order results indicate removal efficiency reaches 98.36%, which is an improvement 9.45% compared ordinary contact angle (WCA) 158°. Meanwhile, anti-icing test, icing time delayed more than four times Compared other similar boards, this features preparation method, easy produce large scale, has low cost, uses commonly available materials, offers strong scalability possessing characteristics such as resistance, anti-icing, abrasion sandstorm resistance. indicates can be many different fields, structural components aircraft spacecraft, body interior parts vehicles, bicycle frames, badminton tennis rackets, bridges, medical devices, enclosures, for electronic products, bulletproof armor, drones, more.

Purpose Copper, the fifth most common metal, has been prized for architectural and aesthetic artwork because of its distinctive colour. On exposure copper metal to air moisture, it corrodes, a blue-green layer appears on surface. The purpose this study develop barrier coating that can protect from corrosion by preventing moisture. Design/methodology/approach present work investigates durable, self-cleaning transparent nanostructured superhydrophobic nano zirconia-based copper. ZrO 2 was prepared sol-gel method further hydrophobically modified. zirconia characterised particle size analysis transmission electron microscopy. Morphological characteristics coated surface were analysed SEM AFM, which revealed nanoscale rough Anti-corrosive properties linear polarise resistance (LPR) electrochemical impedance spectra (EIS). Findings A contact angle in range 149.9°–172.3° confirmed coating’s nature. LPR EIS, indicated efficiency 99.96%. Stability conducted 60 days salt solution, 12% 15% change respectively. stability studies support potential material protection. Originality/value Researchers have developed variety materials protection but these form thick hides lustre. Copper is known pink lustre, such hide or decrease authors proposed sol-gel-assisted prevent without hiding
