Direct polymerization of a novel sulfonated poly(arylene ether ketone sulfone)/sulfonated poly(vinylalcohol) crosslinked membrane for direct methanol fuel cell applications
Sulfonated poly(arylene ether ketone sulfone) copolymers containing carboxylic acid groups (C-SPAEKS) were prepared by direct aromatic nucleophilic substitution polymerization. Novel C-SPAEKS-based crosslinked membranes containing different amounts of sulfonated poly(vinyl
alcohol) (SPVA) were fabricated. The Fourier transform infrared and 1H NMR analyses showed the presence of carboxylic aci...

A facile method to fabricate an antimicrobial coating based on poly(1?vinyl?3?allylimidazolium iodide) (PAVI) and poly(ethylene glycol) dimethyl acrylate (PEGDMA)
Biomedical device-related infections have been a great concern over the past decades. In this work, cationic macromolecules poly(1-vinyl-3-allylimidazolium iodide)
(PAVI) with antibactericidal ability were prepared and grafted on nose clips by surface-initiated polymerization via plasma/autoclaving method. The precursor poly(1-
vinylimidazole) was synthesized by surface-initiated polymeriz...

Preparation of Highly Cross-linked Hydrophilic Porous Microspheres Poly(N,N’-methylenebisacrylamide) and Poly(N,N’-methylenebisacrylamide-co-acrylic acid) with an Application on the Removal of Cadmium
An effective polymerization system was developed for the synthesis of highly-crosslinked hydrophilic monodispersed microspheres with both the micropores
and mesopores inside. A series of poly(N,N’-methylenebisacrylamide) (PMBA)
microspheres with the diameters ranging from 100 to 300 nm were synthesized by
distillation precipitation polymerization with N,N-dimethylacetamide (DMAC) as th...

In vitro degradation behavior of hydroxyapatite/poly(lactide-co-glycolide) composite reinforced by micro/nano-hybrid poly(glycolide) fibers for bone repair.
A poly(glycolide) (PGA)
fiber-reinforced hydroxyapatite/poly(lactide-co-glycolide) (HA/PLGA) composite
with high mechanical strength has been prepared previously. In this paper, in
vitro degradation of ternary composites with different contents of PGA fibers
(0, 30, 50 and 70 wt%) was investigated. Water absorption showed a marked
increase as the degradation progressed, and the composite with...

Hydrolytic Degradation of Biobased Poly(butylene succinate-co-furandicarboxylate) and Poly(butylene adipate-co-furandicarboxylate) Copolyesters under Mild Conditions
It is indispensable to investigate hydrolytic degradation behavior to develop novel biodegradable polyesters. Biobased and biodegradable copolyesters poly(butylene adipate-co-butylene furandicarboxylate) (PBAF) and poly(butylene succinate-co-butylene furandicarboxylate) (PBSF) with BF molar fraction (/BF) between 40 and 60% were synthesized in this study. The hydrolytic degradati...

An injectable hydroxyapatite/poly(lactide-co-glycolide) composite reinforced by micro/nano-hybrid poly(glycolide) fibers for bone repair
Porous nanocomposite of hydroxyapatite/poly(lactide-co-glycolide) (HA/PLGA) is conventionally used in bone tissue engineering but seldom in load-bearing orthopedic applications due to poor mechanical property. This study aimed to fabricate an injectable ternary composite by incorporating different contents of poly(glycolide) (PGA) fibers (0, 30, 50 and 70 wt%) into the nanocomposite HA/PLGA matrix...

Morphological Control of Anisotropic Self-Assemblies from Alternating Poly(p?dioxanone)-poly(ethylene glycol) Multiblock Copolymer Depending on the Combination Effect of Crystallization and Micellization
A novel and facile method was developed for morphological controlling of self-assemblies prepared by crystallization induced self-assembly of crystalline-coil copolymer depending on the combination effect of crystallization and micellization. The morphological evolution of the selfassemblies of alternating poly(p-dioxanone)-block-poly-(ethylene glycol) (PPDO.PEG) multibl...

Temperature dependent morphological evolution and the formation mechanism of anisotropic nano-aggregates from a crystalline-coil block copolymer of poly(p-dioxanone) and poly(ethylene glycol)
The morphological evolution and phase transition of a branched crystalline-coil multi-block copolymer, poly(p-dioxanone)-block-poly(ethylene glycol) (PPDOstar-b-PEG), in aqueous solution under heating and cooling were investigated. The changes in size and morphology of the nano-aggregates were monitored by dynamic light scattering (DLS), transmission electron microscopy (TEM) and ...

Crystallization and morphology of a polymer blend based on linear PPDO and branched poly(p-dioxanone)–poly(lactic acid) block copolymer with immiscible blocks
The crystallization behaviour and morphology of a polymer blend based on branched poly(pdioxanone)–poly(lactic acid) block copolymer (PLA-b-LCB-PPDO) and linear PPDO with immiscible PPDO and PLA blocks has been investigated. Although the PPDO and PLA blocks are immiscible with each other, an interesting interpenetrating spherulite morphology, which always occurs in miscible blend...
