Enhanced Intrinsic Self‐Healing Performance of Mussel Inspired Coating via In‐Situ Cation Capture

Small, Journal Year: 2024, Volume and Issue: unknown

Published: May 11, 2024

Abstract Under damp or aquatic conditions, the corrosion products deposited on micro‐cracks/pore sites bring about failure of intrinsically healable organic coatings. Inspired by mussels, a composite coating poly (methyl methacrylate‐co‐butyl acylate‐co‐dopamine acrylamide)/phenylalanine‐functionalized boron nitride (PMBD/BN‐Phe) is successfully prepared reinforcing steel, which exhibits excellent anti‐corrosion and underwater self‐healing capabilities. The property PMBD derived from synergistic effect hydrogen bonding metal‐ligand coordination bonding, thereby continuous generation can be significantly suppressed through in situ capture cations catechol group. Furthermore, protection ability remarkably improved labyrinth BN inhibition role Phe, desired interfacial compatibility formed bonds between BN‐Phe matrix. current density ( i corr ) PMBD/BN‐Phe determined as 7.95 × 10 −11 A cm −2 . low‐frequency impedance modulus |Z| f = 0 1 Hz remained at 3.47 9 Ω 2 , indicating an ultra‐high efficiency (≈89.5%). It anticipated to provide unique strategy for development robust durability application engineering marine buildings.

The synthesis and characterization of two dimensional materials are in the focus nanomaterial surface science, heterogeneous catalytic nanoelectronic research laying basis for various technological applications. Hexagonal boron nitride (h-BN) is an important member 3D reduced materials. Atomically clean sp2-hybridized 2D nano-layers can be grown on metal supports by different chemical physical vapor deposition techniques. In case a significant lattice mismatch strong interaction at h-BN/metal interface, periodically undulating monolayer - so-called "moirè structure" formed. present review, we address some characteristics h-BN prepared several surfaces, its application as template individual atoms, clusters molecules. Moreover, experimental findings collected about features applications nanosheets supporting We highlight results recent science studies, which emphasize unique role including nanomeshes characteristic adsorption properties, stability activity. few layer defective involving their also subject review. comprehensive overview electronic vibrational states nanoparticles (covered adsorbates, well) monitored spectroscopy tools, e.g. XPS, ARPES, UPS, LEIS, AES, STS HREELS. elaborate structural morphological information nanoobjects obtained scanning probe microscopy (SPM).

Boron nitride quantum dots (BNQDs) have garnered a significant amount of attention in recent years due to their attractive optical properties, high stability, low toxicity, and good biocompatibility. However, our study reveals critical mischaracterization this field, demonstrating that some so-called BNQDs are, fact, carbon (CDs) formed through the unintended carbonization organic solvents during synthesis. Herein, we investigate widely used combination sonication solvothermal conversion for BNQD preparation, using ethanol

Published: March 20, 2024

Quest for ultrathin and highly effective anticorrosion coating films is critical both fundamental community of materials science industrial economics. A two-dimensional hexagonal boron nitride (h-BN) film a newly developed material due to its superior impermeability, thermal stability, chemical stability. However, research in growth properties large-area dense h-BN still lies infancy. Here, we report on the synthesis continuous few-layer (∼4) onto metal surface by vapor deposition (CVD) air seawater environments. Cu coated h-BN, which functions as an anticorrosive coating, exhibits impressively reduced corrosion rate (CR) 3.5% NaCl solution (which mimics environment) when compared bare (approximately 27 times). At 200 °C, can prevent foil's from oxidizing, although doing so will cause significant amount oxide particles simultaneously form surface. In meantime, performance remains unaltered after 100 days atmospheric environment, demonstrating ultrahigh stability resistance as-grown film.
