Nature achieves remarkable function from the formation of transient, nonequilibrium materials realized through continuous energy input. The role enzymes in catalyzing chemical transformations to drive such processes, often as part stimuli-directed signaling, governs both material and lifetime. Inspired by intricate nanostructures living world, this work seeks create transient presence a consumable glucose stimulus under enzymatic control oxidase. Compared traditional glucose-responsive...
A new terpolymer adhesive, poly(2-methoxyethyl acrylate-co-N-methacryloyl 3,4-dihydroxyl-l-phenylalanine-co-heptaisobutyl substituted polyhedral oligomeric silsesquioxane propyl methacrylate) (poly(MEA-co-MDOPA-co-MPOSS) was synthesized by thermally initiated radical polymerization. In this study, we investigated the effect of POSS component on adhesion, mechanical, and optical properties catechol-group containing bioinspired adhesives. The contains catechol group which is known to improve...
Abstract Dynamic hydrogel crosslinking captures network reorganization and self‐healing of natural materials, yet is often accompanied by reduced mechanical properties compared to covalent analogs. Toughening possible in certain materials with processing directional freeze‐casting salting‐out, producing hierarchically organized networks directionally enhanced properties. The implications including dynamic supramolecular alongside such processes are unclear. Here, a prepared from homoternary...
Peptide self-assembly is a powerful tool to prepare functional materials at the nanoscale. Often, resulting have high aspect-ratio, with intermolecular β-sheet formation underlying 1D fibrillar structures. Inspired by dynamic structures in nature, peptide increasingly moving toward stimuli-responsive designs wherein assembled are formed, altered, or dissipated response specific cue. Here, bearing prosthetic glucose-binding phenylboronic acid (PBA) demonstrated self-assemble into an uncommon...
A bioinspired, modular terpolymer adhesive, poly(N-methacryloyl-3,4-dihydroxyl-l-phenylalanine-co-9-(acryloyloxy)butyl anthracene-9-carboxylate-co-acrylic acid), has been synthesized containing three different functionalities: a photo-cross-linking segment, wet interfacial adhesion and water-soluble segment. The adhesive polymer is the first example of single-phase, photo-cross-linkable which does not require additional photoinitiator or other cross-linking agents. demonstrates strong when...
A glucose-based bioadhesive has been synthesized by radical polymerization. The adhesion was significantly enhanced biologically safe SPAAC crosslinking after initial attachment on a substrate.
Supramolecular hydrogels prepared from host–guest physical cross-linking of polymers have versatile utility in a number applications. Routes to integrate stimuli-responsive features these materials are intended add another dimension enhance their functionality. Herein, guest which forms homoternary complex with the cucurbit[8]uril macrocycle was appended ends Pluronic F-127 polymers. This polymer undergoes temperature-responsive micelle formation, upon CB[8] promotes via its interactions...
The traditional electrically conductive adhesives (ECAs) include heterogeneous metallic and/or carbon-based fillers blended with the organic adhesive polymer matrix. However, those heterogeneous-blended ECAs have serious challenges aggregation, weight, synthetic complexity, large filler contents, and price. This work reports a metal-free, high-performance, fully adhesive, poly(N-methacryloyl-3,4-dihydroxyl-l-phenylalanine-co-3-sulfopropyl methacrylate):poly(3,4-ethylenedioxythiophene)...
Abstract A novel CMRF is synthesized from modified silicone oil, containing composite polyurethane microsphere additives, and surface‐coated iron particles. The designed to act as a liquid spring with controllable damping properties in damper system. fluid compressibility characterized by force/displacement measurements. addition of polyurethane‐microspheres increases the strength fluid. It also decreases concentration particles needed order achieve same yield stress commercially available...
ABSTRACT A surface grafting technique is reported for synthesis of poly(pentafluorostyrene) via reversible addition fragmentation chain transfer onto iron (iron oxide) particles. 4‐Methoxydithiobenzoate used the RAFT agent. The molecular weight, morphology, thickness, thermal properties, and monomer conversion grafted polymer are reported. poly(pentafluorostyrene)–iron particles show a higher transition temperature compared to nongrafted because it speculated that covalent bond between...
The synthesis of aromatic polymers containing quinoxalines and preparation composite proton exchange membranes with zirconium sulfate is described. Poly(ether sulfone quinoxalines) was synthesized via condensation polymerization from dihydroxyquinoxaline, bis(4-fluorophenyl)sulfone, bisphenol monomers in N-methylpyrrolidone at 175-180 o C. polymer has a molecular weight ~32,000 Daltons glass transition temperature ~176±2 were sulfonated using chlorosulfonic acid concentrated sulfuric acid....
Poly(ether ketone quinoline) has been synthesized as a composite membrane matrix and molecular weight of ~40,000. Composite membranes for direct methanol fuel cells (DMFCs) have prepared from sulfonated poly(ether (SPEEK)-poly(ether ether ketone)(SPEKQ) blend Nafion with non- surface coated silicotungstic acid (SiWA). The Nafion/surface SiWA excellent potential to be used in DMFCs high feed concentration. particles may protect the "washing out" water suppress crossover. SPEEK-SPEKQ/SiWA...
