Conductive hydrogels are promising multifunctional materials for wearable sensors, but their practical applications require combined properties that difficult to achieve. Herein, we developed a flexible sensor with double-layer structure based on conductive composite hydrogel, which included the outer layer of silicone elastomer (Ecoflex)/silica microparticle film and inner P(AAm-co-HEMA)-MXene-AgNPs hydrogel. Through covalently cross-linking surface hydrogel polymer, bonded thin Ecoflex...
The chemically inert surface and strong ionic bonds make exfoliation functionalization of hexagonal boron nitride (h-BN) difficult. This inevitably increases the interface thermal resistance hinders phonon transfer. Herein, polydopamine (PDA)-coated exfoliated h-BN, denoted as h-BN@PDA, was prepared by a one-step ball milling route. During process, dopamine self-polymerized into PDA on h-BN@PDA in an alkaline aqueous solution. coated contents were estimated to be about 3 wt %. Meanwhile,...
Metastasis is the leading cause of death in colorectal cancer (CRC) patients. By mediating intercellular communication, exosomes exhibit considerable value regulating tumor metastasis. Long non-coding RNAs (lncRNAs) are abundant and participate progression. However, it poorly understood how cancer-secreted exosomal lncRNAs affect CRC proliferation Here, by analyzing public databases we identified a lncRNA SNHG3 demonstrated that was delivered through cells-derived to promote metastasis CRC....
Abstract Two novel monovinyl β ‐cyclodextrin ( ‐CD) monomers are synthesized. Their chemical compositions characterized by means of element analysis, NMR and FT‐IR spectroscopy. The results show that the synthesis techniques used convenient efficient. Using N ‐isopropylacrylamide as a comonomer, two linear copolymers can also be Synthesis route ‐CD monomers. magnified image
Abstract Summary: A novel intelligent delivery system based on the environmental dependence of inclusion effect β ‐cyclodextrin ( ‐CD) with guest molecules, using a ‐CD polymer (CDP) microgel as carrier, is proposed. Compared smart hydrogels, which are driven by phase‐volume transition, controlled release from CDP “host‐guest” effects. With pH‐dependent complexation methyl orange (MO) model system, behavior was tested changing pH, showing that mechanism reasonable. Schematic illustration MO...
Abstract Summary: The present work is focused on investigating the behavior of controlled drug release poly( N ‐isopropylacrylamide) (PNIPA) hydrogels in presence β ‐cyclodextrin ( ‐CD). For this purpose, three types NIPA with ‐CD moieties were synthesized different architectures according to our previous studies. An anti‐cancer (chlorambucil, CLB), which can form an inclusion complex ‐CD, was selected for loading and vitro loaded into via a swelling method. DSC used study interactions...
In this contribution, we report a convenient expression of average number cyclic structures (ANC) and cyclic-average molecular weight (MC) to quantificationally describe the topological defect intramolecular cyclization in highly branched polymers synthesized via A2 + Bn (n ≥ 3) stepwise polymerization strategy by combination nuclear magnetic resonance spectrometry (NMR) size exclusion chromatography (SEC). The ANC MC depend on ratio dendritic, linear, terminal units number-average...
A novel method for switch-controlled drug release was developed through reversible morphology transitions from vesicles to nanoparticles based on supramolecular branched copolymer self-assemblies.
In this work, Fe3O4 nanoparticles anchored with dopamine molecules were developed via bioinspired iron–catechol coordination interactions, and the dopamine-modified surface was linked to matrix through strong interfacial interactions between epoxy vitrimer. Results showed that typical dynamic parameters of vitrimer could be readily adjusted in composites. These findings demonstrate it is efficient adjust properties vitrimers by introducing metal-coordination bonds into networks. The synergy...
Stimuli-responsive conductive hydrogels have a wide range of applications due to their intelligent sensing external environmental changes, which are important for smart switches, soft robotics, and flexible sensors. However, designing stimuli-responsive with logical operation, such as remains challenge. In this study, we synthesized pH-responsive hydrogels, based on the copolymer network acrylic acid hydroxyethyl acrylate doped graphene oxide. Using good flexibility conductivity these...
An effective method was developed to improve the interfacial interaction between Mutiwalled carbon nanotubes (MWCNTs) and epoxy matrix. The performance of thermal conductivity strength vitrimer were enhanced by polydopamine (PDA) coating. Polydopamine is a commonly used photothermal agent, which course, in modifying MWCNTs photoresponsive resin. surface temperature composite with 3% MWCNTs@PDA fillers added increased from room 215 °C 48 s. metal–catechol coordination interactions formed...
Integrating adaptative logic computation directly into soft microrobots is imperative for the next generation of intelligent as well smart materials to move beyond stimulus-response relationships and toward behaviors seen in biological systems. Acquiring adaptivity coveted that can adapt implement different works respond environments either passively or actively through human intervention like Here, a novel simple strategy constructing untethered based on stimuli-responsive hydrogels switch...
A series of soy-based polyamides with different dimer acids and diamines were synthesized using a condensation polymerization technique. The molecular weight prepared from 1,4-phenylenediamine increases greatly reaction temperature above 260°C. physical properties the polyamides, such as glass transition (Tg), melting point (Tm), decomposition (Td), crystalline behavior, mechanical strength strongly depend on their flexibility used. aromatic-based have higher Tg, Tm, Td, stronger than that...

The cyclodextrin (CD) molecule, a host for variety of smaller molecular guests, and hyperbranched polymers both possess molecule cavities in their architectures. If the poly(β-cyclodextrin)s are established using modified β-CD molecules as monomers, inclusion capabilities guests may be enhanced due to combination two different from topography architecture CD chain segments.
