Current single-function superwettable materials are typically designed for either oil removal or water and constrained by density, limiting their widespread applications. Janus membranes with opposite wettability on two surfaces have recently emerged present attractive opportunities on-demand oil/water emulsion separation. Here, a combination strategy is introduced to prepare membrane asymmetric superwettability switchable A mussel-inspired interface introduction cooperating the sequence-confined surface modification not only brings about an but also guarantees outstanding stable remarkable chemical stability surfaces. Specifically, superhydrophilic underwater superoleophobicity can separate surfactant-stabilized oil-in-water emulsions. Conversely, other displays superhydrophobicity superoleophilicity treat water-in-oil Significantly, this presents superior long-term separation without obvious flux decline high recovery ability because of its stability. Furthermore, enhances interfacial floatability at air–water interfaces, enabling design advanced materials. The as-prepared has established cooperated system, overcoming monotony conventional expanding application these specialized oily wastewater treatment.

Abstract In the quest for advanced coatings suitable foldable electronics and photovoltaic systems, there is a pressing need materials that combine transparency with durability. To address this, innovative special horizontal stripes transparent (SHT) coating prepared by capillary gravity self‐assembly methods. This derived from structural principles of corn bracts created through crosslinking epoxy hydrophobic modified SiO 2 an organosilicon prepolymer, bridged double terminal amino polydimethylsiloxane. The pattern surface makes SHT more than glass, bionic structure proven to be highly durable under extreme temperature fluctuations, withstanding tests 150 −20 °C over 192 h, enduring 30 days ultraviolet radiation exposure at 365 nm intensity W m − . Moreover, even after 3000 cycles scissors abrasion, maintained its anti‐fouling properties mechanical resilience. It also demonstrated remarkable chemical stability across range solvents. can easily applied various flexible rigid substrates using brush, poised find broad applications in realm optical devices.

Robust and Lubricating Interface Semi‐Interpenetrating Network on Inert Polymer Substrates Enabled by Subsurface‐Initiated Polymerization

Small, Год журнала: 2024, Номер 20(43)

Опубликована: Июнь 20, 2024

Abstract Lubricating hydrogel coatings on inert rubber and plastic surfaces significantly reduce friction wear, thus enhancing material durability lifespan. However, achieving optimal hydration lubrication typically requires a porous polymer network, which unfortunately reduces their mechanical strength limits applicability where robust wear‐resistance are essential. In the research, coating with remarkable wear resistance surface stability is developed by forming semi‐interpenetrating network substrate at interface. By employing good solvent swelling method, monomers, photoinitiators embedded within substrates' subsurface, followed in situ polymerization under ultraviolet light, creating entangled structure. This approach, offering thicker energy‐dissipating layer, outperforms traditional modifications while preserving anti‐fatigue, hydrophilicity, oleophobicity, other properties. Adaptable to various substrates using suitable solvents, this method provides an efficient solution for durable, lubricating surfaces, broadening potential applications multiple industries.
