The novel comb-type biodegradable graft copolymers based on e-caprolactone and L-lactide were synthesized. Firstly, 2-oxepane-1,5-dione (OPD) was synthesized by the Baeyer–Villiger oxidation of 1,4-cyclohexanedione, and wassubsequently copolymerized with e-caprolactone (CL) to produce poly(2-oxepane-1,5-dione-co-e-caprolactone) (POCL) catalyzed by stannous(II) 2-ethylhexanoate in toluene. Th...

Core-Shell Capsules Based on Supramolecular Hydrogels Show Shell-Related Erosion and Release Due to Confinement
Hydrogel-containing core–shell capsules are useful as drug delivery vehicles for many
biomedical applications, especially when release of incorporated guests can be controlled.
Here, we developed a one-step organic solvent-free method to prepare such core–shell
capsules using a synthetic and a natural supramolecular hydrogel, for the core and shell, respectively. A solution containing ...

Effect of Epoxy Resin on Rheology of PC/Clay Nanocomposites. European Polymer Journal, 2007, 43, 1635-1644.
European Polymer Journal, 2007, 43, 1635-1644.
ABSTRACT:
Polycarbonate/clay nanocomposites (PCNs) were prepared by melt intercalation using epoxy resin as a compatibilizer. The intercalated structure of PCNs was investigated using XRD and TEM. The linear and nonlinear dynamic rheological properties of PCNs were measured by the use of a parallel plate rheometer. The results reveal that the prese...

Study on Rheological Behavior of PBT-Clay Nanocomposites. European Polymer Journal, 2005, 41, 2199-2207.
European Polymer Journal
ABSTRACT: Poly(butylene terephthalate)/montmorillonite composites (PBT/MMT) were prepared by melt intercalation and then investigated using X-ray diffractometer (XRD) and transmission electron microscope (TEM) as well as parallel plate rheometer. It was found that the composites had various phase morphologies with nano-scales and distinct behaviors of a percolation networ...

64. [European Polymer Journal] Adenine-mediated adhesive and tough hydrogel based on hybrid crosslinking
Adhesive hydrogels tend to exhibit poor mechanical property, therefore it’s still challenging to integrate excellent
adhesiveness and toughness in one hydrogel. In this work, we utilized a hybrid crosslinking strategy to
design an adenine-mediated hydrogel by introducing adenine and N,N′-methylene bisacrylamide (MBA) into
polyacrylamide hydrogel. The hybrid crosslinking hydrogel exhib...

63. [European Polymer Journal] Tough hydrogel based on covalent crosslinking and ionic coordination from ferric iron and negative carboxylic groups
In this work, carboxylic groups were introduced to latex microspheres (LMs) to obtain poly(styrene-butyl acrylate)
(P(St-BA)-COOH) LMs with negative charges by a soap-free emulsion polymerization method. Then P(St-
BA)-COOH LMs were added into an aqueous solution composed of acrylamide (AAm) and acrylic acid (AAc). The
P(AAm-co-AAc)-MBA/LMs hydrogel was fabricated after adding redox ini...

【European Polymer Journal】So2 temperature and oxidation multi-responsive homopolypeptide synthesis characterization and exploration of their potential applications
Abstract:
SO2-responsive homopolypeptide with tri(ethylene glycol), 1,2,3-triazole linkages and N-butylimidazolium iodide pendants (P4) were prepared by the ring-opening polymerization of γ-2-(2-(2-chloroethoxy)ethoxy)ethyl-l-glutamic acid based N-carboxyanhydride then post-polymerization to the side-chain, by the nucleophilic substitution of the chloro group in the presence of NaN3, followe...

【European Polymer Journal】Preparation and mechanical properties of strong and tough poly (vinyl alcohol)-polypeptide double-network hydrogels
Abstract：
Poly(vinyl alcohol) (PVA)-polypeptide double-network hydrogels with various ionic liquid (IL)-based polypeptides were prepared by a freezing/thawing method. Tensile tests revealed that the stiffness and toughness of the PVA hydrogels were significantly improved (e.g., 6.3 times the Young’s modulus and 5.8 times the work of extension) by incorporation of IL-based polypeptides. An...

[Journal of the European Ceramic Society] Additive manufacturing of green ceramic by selective laser gasifyingof frozen slurry
The slurry-based additive manufacturing (AM) of ceramics involves a drying process to form solid support; however, the drying process is time-consuming, and the support is not easily removed. We propose a new AM process for green ceramic that includes freezing a layer of aqueous ceramic slurry, laser gasifying of the frozen-layer ice to process 2D green ware, and removing the support in water to...

56. [European Polymer Journal] The role of chemical and physical crosslinking in different deformation stages of hybrid hydrogels
Hybrid crosslinking hydrogels have exhibited excellent mechanical properties, however, the relationship between chemical and physical crosslinking in the various deformation stages is still indistinct. Here, we have explored a novel hybrid hydrogel by inducing low density of chemical crosslinking into latex particle hydrogels (LP-Gel), in which latex particles act as physical crosslinking center...
