Coatings with only passive protection cannot offer long-term anticorrosion on metals. Eco-friendly sustainable and responsive coating for active/passive corrosion is desirable to extend the service life of Here, benzotriazole (BTA)-metal organic frameworks (Cu-MOFs, UiO-66) were embedded in silica (SiO2) by one-step electrodeposition copper. Combined capability MOFs active BTA inhibitor, composite (BTA-MOF/SiO2) exhibited high stable resistance, confirmed microstructure characterizations electrochemical tests. As a result, as-prepared superhydrophobicity water contact angle 154.2°. With loading BTA-MOF SiO2 coating, impedance modulus at 0.01 Hz increased ∼10-fold current density decreased 3.472 × 10–9 A·cm–2. Immersion salt spray tests coating. The release inhibitor endows responsively anticorrosive behavior. active-passive ability makes good candidate metals used highly salty environments.

Advanced Science, Год журнала: 2024, Номер unknown

Опубликована: Сен. 19, 2024

Abstract Functional coatings, including organic and inorganic play a vital role in various industries by providing protective layer introducing unique functionalities. However, its design often involves time‐consuming experimentation with multiple materials processing parameters. To overcome these limitations, data‐driven approaches are gaining traction science. In this paper, recent advances research development (R&D) for functional highlighting the importance, data sources, working processes, applications of paradigm summarized. It is begun discussing challenges traditional methods, then introduce typical processes. demonstrated how enable identification correlations between input parameters coating performance, thus allowing efficient prediction design. Furthermore, carefully selected case studies presented across diverse that exemplify effectiveness methods accelerating discovery new coatings tailored properties. Finally, emerging directions, involving integrating advanced techniques from different addressed. Overall, review provides an overview R&D shedding light on potential future developments.

Oleogel Microsphere‐Based Composite Protective Coatings with Room‐Temperature Self‐Healing Enabled by a “Soft + Hard” Hybrid Architecture

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Июнь 10, 2024

Abstract Intrinsically self‐healing coatings are compelling candidates for highly reliable anti‐corrosion technologies because of their easy implementation, low cost, and repeatable self‐healing. However, most these require intervention to initiate healing due the locking chain segments under ambient conditions (to provide sufficient mechanical strength). Herein, a “soft + hard” hybrid architecture strategy preparing oleogel‐based protective with room‐temperature is proposed by embedding “soft” viscoelastic oleogel microspheres (OMs) in “hard” waterborne epoxy matrix. Such decoupled design affords both instantaneous without external stimuli (crack narrowing within 10 min protection recovered 5 h) good properties (improved wear resistance an 80% reduction friction coefficient, 63% volume, as well maintained adhesion strength 96%). The slippery hydrophobic OMs also bring anti‐biofouling, interfacial water repellency, inhibitor loading‐release features, leading superior corrosion (>10 Ω cm 2 impedance modulus throughout 110 d) rather than just This work demonstrates feasible approach integrating future coating design.
