Noncovalent interactions, which usually feature tunable strength, reversibility, and environmental adaptability, have been recognized as driving forces in a variety of biological chemical processes, contributing to the recognition between molecules, formation molecule clusters, establishment complex structures macromolecules. The marriage noncovalent interactions conventional covalent polymers offers systems novel mechanical, physicochemical, properties, are highly dependent on binding mechanisms that can be illuminated via quantification. This review systematically discusses nanomechanical characterization typical polymeric systems, mainly through direct force measurements at microscopic, nanoscopic, molecular levels, provide quantitative information (e.g., ranges, strengths, dynamics) behaviors. fundamental understandings intermolecular interfacial then correlated macroscopic performances series noncovalently bonded polymers, whose functions stimuli-responsiveness, self-healing capacity, universal adhesiveness) customized manipulation providing insights into rational design advanced materials with applications biomedical, energy, environmental, other engineering fields.

Engineering In Situ Catalytic Cleaning Membrane Via Prebiotic‐Chemistry‐Inspired Mineralization

Advanced Materials, Год журнала: 2023, Номер 35(49)

Опубликована: Окт. 3, 2023

Pressure-driven membrane separation promises a sustainable energy-water nexus but is hindered by ubiquitous fouling. Natural systems evolved from prebiotic chemistry offer glimpse of creative solutions. Herein, prebiotic-chemistry-inspired aminomalononitrile (AMN)/Mn2+ -mediated mineralization method reported for universally engineering superhydrophilic hierarchical MnO2 nanocoating to endow hydrophobic polymeric membranes with exceptional catalytic cleaning ability. Green hydrogen peroxide catalytically triggered in-situ the mineralized and enabled operando flux recovery reach 99.8%.

Abstract Articular cartilage has an appropriate multilayer structure and superior tribological properties provides a structural paradigm for design of lubricating materials. However, mimicking articular traits on prosthetic materials with durable lubrication remains huge challenge. Herein, ingenious three‐in‐one strategy is developed constructing cartilage‐like bilayer hydrogel coating the surface ultra‐high molecular weight polyethylene (BH‐UPE), which makes full use conceptions interfacial interlinking, high‐entanglement crosslinking, interface‐modulated polymerization. The tightly interlinked UPE substrate through hydrogel‐UPE interchain entanglement bonding. chains are highly entangled each other to form dense tough layer negligible hysteresis load‐bearing by reducing amounts crosslinker hydrophilic initiator p.p.m. levels. Meanwhile, polymerization monomers in top region suppressed via polymerization, thus introducing porous effective aqueous lubrication. As result, BH‐UPE exhibits ultralow friction coefficient 0.0048 during 10 000 cycles under load 0.9 MPa, demonstrating great potential as advanced bearing material disc prosthesis. This work may provide new way build stable coatings have important implications development biological

Water-energy sustainability will depend upon the rapid development of advanced pressure-driven separation membranes. Although energy-efficient, water-treatment membranes are constrained by ubiquitous fouling, which may be alleviated engineering self-cleaning membrane interfaces. In this study, a metal-polyphenol network was designed to direct armorization catalytic nanofilms (ca. 18 nm) on inert polymeric The chelation-directed mineralized coating exhibits high polarity, superhydrophilicity, and ultralow adhesion crude oil, enabling cyclable oil-in-water emulsion separation. in-place flux recovery rate exceeded 99.9%, alleviating need for traditional ex situ cleaning. nanoarmored exhibited 48-fold 6.8-fold figures merit regeneration compared control simple hydraulic cleaning, respectively. Precursor interaction mechanisms were identified density functional theory calculations. Chelation-directed offers promise sustainable applications in catalysis, biomedicine, environmental remediation, beyond.

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

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

Опубликована: Фев. 10, 2024

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.
