It is discovered that poly(vinyl alcohol) (PVA) hydrogel prepared using the freezing/thawing method can self-repair at room temperature without need for any stimulus or healing agent. The autonomous self-healing process be fast mechanically strong PVA yielding a high fracture stress. Investigation on effect of preparation conditions points out hydrogen bonding between chains across interface cut surfaces origin phenomenon. key an effective to have appropriate balance concentration free...
A double-network polymer hydrogel composed of chemically cross-linked poly(ethylene glycol) (PEG) and physically poly(vinyl alcohol) (PVA) was prepared. When the (70 wt % water) is subjected to freezing/thawing treatment under strain, enhanced physical network as a result crystallization PVA chains can stabilize deformation after removal external force at room temperature. Subsequent disruption by heating allows for recovery initial shape hydrogel. Moreover, exhibits self-healing capability...
A new optically triggered shape memory composite material was prepared and investigated. Poly(ε-caprolactone) (PCL)-surface functionalized AuNPs were loaded in a thermosensitive shape-memory polymer (SMP) matrix of biodegradable, branched oligo(ε-caprolactone) (bOCL) cross-linked with hexamethylene diisocyanate (HMDI), referred to as XbOCL. By making use localized photothermal effect arising from the SPR absorption AuNPs, we are able demonstrate an spatially selective recovery process,...
Inspired by the "brick-and-mortar" structure and remarkable mechanical performance of nacre, many efforts have been devoted to fabricating nacre-mimicking materials. Herein, a class graphene oxide (GO) based artificial nacre material with quadruple hydrogen-bonding interactions was fabricated functionalization polydopamine-capped (PDG) 2-ureido-4[1H]-pyrimidinone (UPy) self-complementary units followed supramolecular assembly process. The displays strict structure, PDG nanosheets as brick...
A security inspection system exemplifies human-machine collaboration, and enhancing its safety reliability through advanced technology remains a key research priority. While deep learning has incrementally improved the autonomous capabilities of equipment for automatic contraband detection, gap persists between current technological practical implementation. Recognizing that humans excel at learning, reasoning, collaborating, while artificial intelligence offers normative, repeatable,...
Gold nanorods (AuNRs) are confirmed to have excellent and repeated photothermal properties under near-infrared (NIR)-light irradiation above 780 nm. However, AuNRs easily leaked out from local pathological tissues circulated in the body, reducing therapy (PTT) efficacy. By complexing with a scaffold via interactions, might be dispersed fixed tumor site. Thus, based on mussel-mimetic adhesion concept, were designed coated polydopamine (PDA), then prepared polydopamine-coated (AuNR-PDA)...
Self-healable hydrogels based on the dynamically reversible boronate ester or borate bonds are usually prepared by reacting boronic acid boric with diol compounds polymer-like poly(vinyl alcohol) bearing a hydroxyl group in each monomer unit. Herein, we report finding that not only facilitates preparation but also extends range of self-healable this kind. By simply copolymerizing commercially available N,N-dimethylacrylamide and 2-hydroxyethyl acrylate (8:2 weight ratio) presence one-pot...
Incorporation of PDA@ZIF-8 can simultaneously enhance the CO<sub>2</sub> separation performance and interfacial adhesion MMMs.
A novel supramolecular block glycopolypeptide, designed to have the viral building blocks and be sensitive CO2, a physiological stimulus, was prepared via orthogonal coupling of two end-functionalized biopolymers, dextran with β-cyclodextrin terminal (Dex-CD) poly(l-valine) benzimidazole tail (BzI-PVal), respectively, driven by end-to-end host-guest interactions. Due CO2-cleavable CD/BzI connection, both vesicular fibrous aggregates this copolymer self-assembled in aqueous solution can...

We developed simple methods to prepare shellac composite films/coating with practical application value.
A novel mixed matrix membrane was fabricated by establishing montmorillonite (MMT) functionalized with poly(ethylene glycol) methyl ether (PEG) and aminosilane coupling agents in a PEBA membrane. The functional MMT played multiple roles enhancing performance. First, the channels could be used as high-speed facilitated transport channels, which movable metal cations acted carriers of CO2 to increase permeability. Second, due mobility long-chain aminos reversible reactions between amine...
A general method for very fast and efficient optical healing of crystalline polymers is reported. By loading a small amount gold nanoparticles (AuNPs) in either poly(ethylene oxide) (Tm ≈ 63 °C) or low-density polyethylene 103 °C), the heat released upon surface plasmon resonance (SPR) absorption 532 nm light by AuNPs can melt crystallites interfacial region two polymer pieces brought into contact; subsequent recrystallization chains on cooling merges one. The fracture strength such repaired...

While polylactide (PLA) is considered to be a promising renewable materials, broader application hindered by its brittle nature and high cost. PLA-based nanocomposites with enhanced toughness were fabricated blending of commercial PLA core–shell starch-based nanoparticles (CSS NPs), in which the CSS NPs synthesized via gelatinization esterified starch form hard core, followed soap-free emulsion copolymerization ethyl acrylate poly(ethyl acrylate) (PEA) as outer shell. A synergistic...
2-Ureido-4[1H]-pyrimidinone (UPy) is widely deployed in bulk materials for switching phase or physical cross-linking because of exceptional quadruple H-bond strength and thermal reversibility. However, utilization UPy dimers as the to prepare shape memory hydrogels has been rarely explored due competition with water molecules. Herein, high contents are synthesized exhibit excellent ability, even at contents. By introduction tetraphenylporphyrin into hydrogels, behavior can further be...
