Abstract Nowadays, much attention is paid to the development of high‐performance and multifunctional materials, but it still a great challenge obtain polymer materials with high mechanical properties, self‐healing multifunctionality in one. Herein, an innovative strategy proposed satisfactory waterborne polyurethane (PMWPU‐Bx) by situ anchoring 3‐aminophenylboronic acid (3‐APBA) pyrene‐capped (PMWPU) via supramolecular interactions. The multiple functional sites inherent 3‐APBA can produce interactions groups on PMWPU, promoting aggregation hard domains network, which confers PMWPU‐Bx strength (7.9 MPa) modulus (243.2 MPa). Meanwhile, dynamic natures boronic ester bonds formed condensation endow efficiency. Additionally, exhibits fluorescence tunability due controlled π–π stacking. In this research, molecules onto polymers through synchronously achieves performance multi‐functionality polyurethanes, also broadens their potential applications fields optical anticounterfeiting encrypted information transmission.

Washable Superhydrophobic Cotton Fabric with Photothermal Self-Healing Performance Based on Nanocrystal-MXene

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Superhydrophobic fabrics suffer from being commonly penetrated by moisture after laundering, seriously deteriorating their water repellency air drying. Numerous researchers have successfully recovered superhydrophobicity drying in fluid ovens; however, high energy consumption and equipment dependence limit practical applications. Herein, the superhydrophobic photothermal self-healing cotton fabric (SPS fabric) was fabricated depositing a composite layer of cellulose nanocrystal-MXene (C-MXene) polyacrylate (PA) coatings on cloth. Superior conversion SPS performance enables its 10.5-56.8 °C greater temperature than that pure hydrophobic under different simulated solar light intensities. After washing, can spontaneously restore with ≈100% efficiency 30 mW·cm-2 irradiation; contrast, single recover only ≈71.2%. Even 10 washing cycles, recovery decreases 0.1%, exhibiting excellent laundering durability. The retain ultralong time antifrosting (2760 s) antifreezing (4080 capacities due to sustainable repellency. Remarkably, capability is attributed fact coiled nonpolar alkane chains be restored straight state autothermal drive, confirmed through element analyses molecular dynamics simulations.

Research Advances in Low Surface Energy Antifouling Coatings for Ships With Structural Bionic Properties

Polymers for Advanced Technologies, Год журнала: 2025, Номер 36(3)

Опубликована: Март 1, 2025

ABSTRACT Ship surface fouling poses serious constraints on ship navigation and the marine environment. Now that traditionally harmful antifouling coatings have been banned worldwide, development of new for ships are environmentally friendly functionally stable is imminent. Low energy with structural biomimetic properties safest, most friendly, effective breakthrough in preventing deposits hull surfaces. This article first explains mechanism coatings, comprehensively describes morphology bionic microstructure, summarizes construction method structure. On this basis, low fluorine‐containing silicone‐containing materials, as well current application ships, analyzed. In addition, stimulus–response coatings. reviews research progress based structures recent years, presents challenges future directions field, provides unique insights to further optimize performance these
