Heterogeneous distribution of magnetic nanoparticles in reactive polymer blends
This work attempts to study the influence of a reactive compatibilizer on the uneven distribution of Fe3O4 nanoparticles in polystyrene (PS)/polyamide 6 (PA6) blends and to present a novel, low-cost approach for fabricating PA6-based magnetic microspheres. By adding terminal maleic anhydride functionalized PS (FPS), we were able to observe significant reductions in both the PA6 do...

Real-Time Membrane Fusion of Giant Polymer Vesicles
Membrane fusion is very important for the formation of many complex organs in metazoans throughout evolution, such as muscles, bones, and placentae. Lipid vesicles (liposomes) are frequently used as model membranes to study the fusion process. This work demonstrates for the first time the real-time membrane fusion of giant polymer vesicles by directly displaying a series of high-resolution ...

Real-Time Membrane Fission of Giant Polymer Vesicles
Cooperation of mother and daughter vesicles, which are self-assembled from an ill-defined hyperbranched copolymer, leads to fission of the daughter membrane in a cytomimetic process (see picture; red: mother vesicle, green: daughter vesicle). This is the first example of giant polymer vesicles (5–200 μm) being used as model membranes.

A physical gel made from hyperbranched polymer gelator
A novel hyperbranched polymer gelator has been synthesized, which can self-assemble into the thermoreversible physical gel in DMF, DMAC, pyridine, DMSO or NMP with the driving force of hydrogen bonds among amide and amine groups of the highly branched macromolecules.

[Polymer International] Preparation of inner asymmetric composite microspheres
Novel inner asymmetric composite microspheres were prepared by encapsulating surface-modified magnetic particles via mini-emulsion polymerization. Most of the surface-modified magnetic particles encapsulated into the polymer matrix aggregate in one side of each microsphere, while only a few particles randomly disperse in the remaining part. The magnetic content of these novel asymmetric composit...

Synthesis and characterization of a luminescence metallosupramolecular hyperbranched polymer
A luminescence supramolecular hyperbranched polymer is reversibly fabricated by successively adding acid and base to a solution of an AB(2) platinum(II) monomer in dichloromethane on the basis of acid-base controllable host-guest recognition of dibenzo[24]crown-8 moieties with dialkylammonium ion centers.

Concentration and acid-base controllable fluorescence of a metallosupramolecular polymer
A metallosupramolecular polymer (MP-Zn) bearing dibenzo-24-crown-8 (DB24C8) arms is constructed by coordinating Zn2+ with a conjugated bis-terpyridine ligand, which indicates concentration-dependent emissions from cyan to white to yellow. Successively, reversible emissions are realized by acid-base controllable recognition of DB24C8 moieties in MP-Zn with dialkylammonium ion centers.

Novel halogen-free flame retardant polymer foams
This paper reported a novel halogen-free flame retardant poly (vinyl alcohol) (PVA) foam with intrinsic flame retardant characteristics prepared through continuous extrusion using water as blowing agent. The morphology, cellular structure, mechanical properties and flame retardancy of the foams were systematically investigated. The experiments showed that PVA was not only the flame retardant tar...

Biodegradable and intelligent conducting polymer for tissue engineering application
Tissue and organ failure, caused from injury or other type of damage, is a major health problem. The traditional treatments include organ transplantation, surgical reconstruction and mechanical or synthetic devices. Tissue engineering is emerging as a promising alternative or complementary solution for therapy of tissue and organ failure. The synthetic biomaterials, such as poly(lactic ac...
