Abstract It is a challenge to synthesize materials that possess biological tissue‐like properties: strain‐stiffening, robust yet compliant, sensitive, and water‐rich. Herein, ferric ion‐induced salting out coordination cross‐linking strategy presented create hierarchical hydrogel network, including dipole–dipole interactions connected curved chains, acrylonitrile (AN)‐rich clusters, homogeneous iron‐ligand interactions. The design allows the network deform stress‐free under small strain by...
Rapid, accurate, and real-time measurements of ocean salinity are great importance for a host scientific, commercial, defense applications. We demonstrate highly sensitive, fast-responding fiber-optic sensor that integrates long-period fiber gratings (LPFGs) with ionic strength-responsive hydrogel. The submicron-thick hydrogel was synthesized via layer-by-layer electrostatic assembly partially quaternized poly(4-vinylpyridine) (qP4VP) poly(acrylic acid), followed by chemical cross-linking....
The mechanically robust estradiol-loaded PHM H -Si hydrogel could not only release estradiol sustainably and locally but also be a stable barrier in the uterine cavity, which may novel effective treatment for IUAs.
Abstract Compatibility between polymers with different glass transition temperatures controls the thermomechanical properties of blends. This work explores segmental dynamics poly(methyl acrylate) (PMA) chains when they are blended rigidities and miscibility. Inspired by intriguing dynamic asymmetry within interfacial layer nanoparticles, this study aims to understand heterogeneity in dynamically asymmetric blends PMA/poly(methyl methacrylate) (PMMA), PMA/polystyrene (PS), PMA/poly(ethylene...
Immiscible blends of poly(methyl acrylate) (PMA) and methacrylate) (PMMA) exhibit component dynamics confinement effect at the PMA/PMMA-g-Fe 3 O 4 interface, suggesting new routes to control interface dynamics.
The conductivity and charge transport mobility of conjugated polymers (CPs) are largely correlated with their degree crystallinity, rendering the crystallization CPs an important endeavour. However, such tasks can be challenging, especially in absence sidechain functionalization. In this study, we demonstrate that incorporation a small amount oligomers, specifically tetraaniline, induce parent polymer, polyaniline, through single-step self-assembly process. resulting crystals compositionally...
The entanglements of dynamically asymmetric polymer layers influence relaxations nanoparticles in nanocomposites. In this work, the dynamics polymer-adsorbed and polymer-grafted a poly(methyl acrylate) matrix was investigated using X-ray photon correlation spectroscopy (XPCS) to understand role chain rigidity chemical heterogeneities particle dynamics. Locations dynamic close away from surfaces were examined with comparison adsorbed grafted nanoparticles. Our results show that around...
Abstract Materials are more easily damaged during accidents that involve rapid deformation. Here, a design strategy is described for electronic materials comprised of conducting polymers defies this orthodox property, making their extensibility and toughness dynamically adaptive to deformation rates. This counterintuitive property achieved through morphology interconnected nanoscopic core–shell micelles, where the chemical interactions stronger within shells than cores. As result,...
Thermally activated shear stiffening viscoelastic fluid can help to improve the performance of dampers and high-temperature adhesives.

We report linear rheological responses grafted particle before after large-amplitude oscillatory application. found that interfacial mixing short grafts chemically different long matrix...
The strength of interfacial attractions between polymer chains and nanoparticles is known to control the mobility viscoelastic properties in nanocomposites. We chose layers around magnetic consist two different miscible polymers measured energy absorption rates as particles dissipate while they rotate under a high-frequency alternating field. Local viscosities were calculated from rotational relaxation times using classical model. changes local attributed rigidity adsorbed chemical...
Polymer-grafted nanoparticles offer several advantages in designing electrolyte systems for their uses fuel cells, supercapacitors, or actuators. In this work, stabilization of poly(methyl methacrylate) (PMMA)-grafted magnetic with polystyrene sulfonate (PSS) end domains ionic liquid/cosolvent mixtures is presented. We propose that anions and cations pertaining to liquid preferentially interact the methyl groups PMMA sulfonated PSS, respectively. These interactions can be used mitigate whole...
Intermixing between chemically different polymers around nanoparticles creates heterogeneous layers, exhibiting unusual dynamic anomalies due to confinement and coupling phenomena in polymer nanocomposites. Interfacial mixing of chains is possible when adsorbed are mobile above their glass-transition temperature, leading enhanced entanglement density at the interphase. Linear rheology data nanocomposites with interphases were analyzed over a wide frequency range investigate role chain...
