[Macromol. Rapid Commun.] pH- and Sugar-Induced Shape Memory Hydrogel Based on Reversible Phenylboronic Acid-Diol Ester Bonds
A simple strategy is provided to construct a novel pH and sugar-induced
shape memory hydrogel based on the dynamic phenylboronicacid-diolinteractions formed
byphenylboronic acid modified sodium alginate (Alg-PBA) and poly(vinyl
alcohol)(PVA). The dynamic PBA-diol ester bonds would serve as temporary
crosslinks and stabilize the deformed shape of the hydrogel.The disassociation
of the PBA-diol este...

Microorganism inspired hydrogels: super/macro hierarchical pore, rapid swelling rate and high adsorption
Based on the production of baking bread, rolls, cake, beer or Chinese steamed bread, a novel microorganism inspired macro/super-porous hydrogel composed of specific polymers and single-celled fungi, yeast, was prepared by the production of carbon dioxide (CO2) via a fermentation method. The appearance, porous structure, swelling behavior and adsorption properties of the resulting hy...

[Macromol. Rapid Commun.] Microwave-Assisted Synthesis of GlycopolymerFunctionalized Silver Nanoclusters: Combining the Bioactivity of Sugar with the Fluorescence and Cytotoxicity of Silver
Copolymers of
2-(methacrylamido)glucopyranose (MAG) and methacrylic acid (MAA) are
synthesized by RAFT polymerization and then used as templates to prepare
glycopolymer-functionalized Ag nanoclusters (Gly-Ag NCs) through
microwave irradiation. Polymers and the resulting nanoclusters are
characterized by NMR, GPC, UV-Vis, SEM, TEM, AAS and fluorescence
spectroscopy. The bio-activity of the ...

Silk sericin/poly (NIPAM_LMSH) nanocomposite hydrogels: rapid thermo-responsibility and good carrier for cell proliferation
To overcome the fragility of chemical cross-linked hydrogel and improve the cell compatibility of poly(Nisopropylacrylamide) hydrogel, physical cross-linker lithium magnesium silicate hydrate (LMSH) and silk sericin (SS) created by Bombyx mori (silkworms) were adopted as physical cross-linker and biocompatible monomer
to prepare SS/poly(NIPAM/LMSH) nanocomposite hydrogels. Th...

A novel multi-responsive polyampholyte composite hydrogel with excellent mechanical strength and rapid shrinking rate
Series of hydrophilic core–shell microgels with cross-linked poly(N-isopropylacrylamide) (PNIPAAm) as core and poly(vinyl amine) (PVAm) as shell are synthesized via surfactant-free emulsion polymerization. Then, the microgels are treated with a small amount of potassium persulfate (KPS) to generate free radicals on the amine nitrogens of PVAm, which subsequently initiate the graft copolymerizatio...

Genipin-cross-linked thermosensitive silk sericin/ poly(N-isopropylacrylamide) hydrogels for cell proliferation and rapid detachment
To overcome release of silk sericin (SS) from semiinterpenetrating polymer network (semi-IPN) SS/poly(N-isopropylacrylamide) (PNIPAm) hydrogels, natural biocompatible
genipin (GNP) was adopted as cross-linking agent of SS. The GNP/SS/PNIPAm hydrogels with various GNP contents were prepared by radical polymerization. Depending on GNP content, the resultant hydrogels p...

Sensitive and rapid hydrogen sensors based on Pd–WO3 thick films with different morphologies
WO3 loaded with noble metals is well-known to be sensitive to reducing gases and can be used as hydrogen sensor. This paper presents a simple and attractive method concerning the preparation of hydrogen sensors based on Pd-loaded WO3 nanocomposites with different morphologies. The influences of the morphology of WO3 and the palladium growth on its surface on the hydrogen sensing per...

Self-Assembled FeCo/Gelatin Nanospheres with Rapid Magnetic Response and High Biomolecule-Loading Capacity
In this work, surface-adsorbed gelatin polypeptide chains ensure the biocompatibility. Briefly, uniform 100- nm FeCo/gelatin nanospheres are assembled from in situ formed small primary FeCo NCs with the aid of gelatin polypeptides. During the assembly, the small primary FeCo NCs are encapsulated by gelatin chains through the multidentate coordination mode, followed by orderly assembly into ...

Macromol. Rapid Commun. 2010, 31, 1622–1627. Multicomponent Phase Change Microfibers Prepared by Temperature Control Multifluidic Electrospinning
Multicomponent phase change microfibers, which can storage and release thermal energy in a stepwise manner, are firstly prepared through a facile one-step multifluidic compound-jet electrospinning with temperature control. The multiresponsive effect benefits from a special multichannel tubular microstructure that could controllably encapsulate different phase change materials into the channels ind...
