Fire-retardant coatings represent a universal cost-effective approach to providing fire protection for various substrates without compromising substrates' bulk properties. However, it has been attractive yet highly challenging create waterborne polymeric fire-retardant combining high-efficiency, generally strong adhesion, and self-repairability due lack of rational design principles. Inspired by mussel's unique adhesive, self-healing, char-forming mechanisms, herein, "group synergy" strategy is proposed realize the combination high efficiency in fully coating via multiple synergies between catechol, phosphonic, hydroxyethyl groups. As-created exhibits rapid room-temperature self-healing ability adhesion (non)polar dynamic non-covalent interactions enabled these Because functional groups enable formation robust structurally intact slightly expanded char layer upon exposure flame, 200 µm-thick such can make extremely flammable polystyrene foam very difficult ignite self-extinguishing, which far outperforms previous strategies. Moreover, this provide exceptional variety from polymer foams, timber, fabric steel. This work presents promising material principle next-generation sustainable high-performance general protection.

Dual‐Protection Inorganic‐Protein Coating on Mg‐Based Biomaterials through Tooth‐Enamel‐Inspired Biomineralization

Advanced Materials, Год журнала: 2024, Номер 36(21)

Abstract Biocompatible magnesium alloys represent revolutionary implantable materials in dentistry and orthopedics but face challenges due to rapid biocorrosion, necessitating protective coatings mitigate dysfunction. Directly integrating durable onto Mg surfaces is challenging because of intrinsic low coating compactness. Herein, inspired by tooth enamel, a novel highly compact dual‐protection inorganic‐protein (inorganic Pro ) situ constructed on through bovine serum albumin (BSA) protein‐boosted reaction between sodium fluoride (NaF) substrates. The association ions BSA establishes local hydrophobic domain that lowers the formation enthalpy NaMgF 3 nanoparticles. This process generates finer nanoparticles function as “bricks,” facilitating denser packing, consequently reducing voidage inside over 50% reinforcing mechanical durability. Moreover, incorporation plays two synergistic roles: 1) acting “mortar” seal residual cracks within coatings, thereby promoting compactness tripling anticorrosion performance, 2) mitigating fouling‐accelerated biocorrosion complex biosystems via tenfold resistance against biofoulant attachments, including biofluids, proteins, metabolites. innovative strategy, leveraging proteins alter inorganic reactions, benefits future design for Mg‐based other metallic with tailored antifouling performances.

Self-healing polymers and nanocomposites form an important class of responsive materials. These materials have the capability to reversibly heal their damage. For aerospace applications, thermosets thermoplastic been reinforced with nanocarbon nanoparticles for self-healing structural This review comprehends use in sector. The behavior depends on factors such as microphase separation, matrix–nanofiller interactions inter-diffusion polymer–nanofiller. Moreover, can be achieved through healing agents nanocapsules nanoparticles. mechanism has found operate via physical or chemical interactions. used design components, panels, laminates, membranes, coatings, etc., recover damage space Future research must emphasize new high-performance polymeric structures.

With increasingly severe metal corrosion, coating preparation with high-performance corrosion protection has attracted more attention. Herein, the encapsulation of inhibitor 8-hydroxyquinoline (8-HQ) as well self-healing agent linseed oil (LO) in polyvinyl alcohol (PVA) and chitosan (CS) shells were realized by coaxial electrospinning, which was recorded PVA/CS@LO/8-HQ core–shell nanofibers. nanofibers employed to promote epoxy coating. The anticorrosion mechanism that change local pH on surface stimulated release 8-HQ from nanofibers, then chelated iron ions form a complex. When cracks occurred caused rupture LO released reacted oxygen cure them so could be healed autonomously. dynamic potential polarization curves showed inhibition efficiency compound + reached 87.54%, 90.31%, 85.57% at = 3, 7, 11, respectively, higher than single inhibitor. Density functional theory calculations revealed combination, forming hydrogen bond interaction, promoted adsorption inhibitors steel surface. Scanning Kelvin probe electrochemical impedance spectroscopy proved properties These results demonstrated embedding obtain properties, mechanical
