Improving hemocompatibility of styrene-b-(ethylene-co-butylene)-b-styrene elastomer via N-vinyl pyrrolidone-assisted grafting of poly(ethylene glycol) methacrylate
关键字：Styrenic thermoplastic elastomer, Melt free radical grafting, Poly(ethylene glycol)
In this work, in order to enhance the grafting degree, N-vinyl pyrrolidone (NVP) was used to assist the melt grafting of the macromonomer-poly(ethylene glycol) methyl ether methacrylate (PEGM)-which has good hemocompatible property, onto styrene-b-(ethylene-co-butylene)-b-styrene (SEBS) elastomer with free radical initiator. The grafting degree of PEGM with NVP assistance was incr...

polypropylene blends with poly (styrene-b-(ethylene-co-butylene)-b-styrene) under irradiation: A comparative investigation
关键字：Electron beam irradiation, Poly (styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS), Polypropylene (PP), Crystallinity, Molecular weight
The aim of this paper is to investigate the stabilization of polypropylene in the poly (styrene-b-(ethyleneco-butylene)-b-styrene) (SEBS)/polypropylene (PP) blends under irradiation with respect to PP. The PP films, SEBS/PP films were subjected to electron beam irradiation and characterized by wide angle X-raydiffraction (WAXD), differential scanning calorimetry (DSC), gel permeation chromato...

Influence from Thermal Elimination Temperature of Precursor Polymer and Film-forming Methods on the Photophysics of the Poly（2,5-didodecyloxy-p-phenylenevinylene）
关键字：poly（p-phenylenevinylene），synthetic methods，photophysics，polymer precursor，morphology
A series of poly（p-phenylenevinylene）s （PPVs） with good solubility were synthesized from thermal elimination of precursor poly（2,5-didodecyloxy-p-phenylenevinylene） at different temperature via Wessling method. The polymer photophysics were influenced by the thermal elimination condition, which was consistent with NMR and IR characterizations. The additional absorption peak at longer wavelen...

Preparation and Surface-enhanced Raman Performance of Electrospun Poly(vinyl alcohol)/ high-concentrationgold Nanofibers
关键字：Gold nanoparticles，Poly (vinyl alcohol)，Electrospinning，Surface-enhance Raman scattering
A facile approach to prepare electrospun poly(vinly alcohol) (PVA) nanofibers with high concentration of gold nanoparticles (Au NPs) on the fibers, had been developed. These PVA/Au nanofibers could be used as flexible surface-enhanced Raman scattering (SERS) substrates. Relatively high concentration of PVA aqueous solution (10 wt %) was used as the stabilizing agent for gold salt precursor, as wel...

Preparation and characterization of PSSA/PVA catalytic membrane for biodiesel production
关键字：Biodiesel Poly(vinyl alcohol) (PVA) Poly(styrene sulfonic acid) (PSSA) Catalytic membrane Esteri?cation
Poly(styrene sulfonic acid) (PSSA)/Poly(vinyl alcohol) (PVA) blend membranes prepared by the solution casting were employed as heterogeneous acid catalysts for biodiesel production from acidic oil obtained from waste cooking oil (WCO). The membranes were annealed at different temperature in order to enhance their stability. The structure and properties of the membranes were investigated by means o...

Background: Two methoxyl poly(ethylene glycol)-poly(L-histidine)-poly(L-lactide) (mPEG-PH-PLLA) triblock copolymers with different poly(L-histidine) chain lengths were synthesized. The morphology and biocompatibility of these self-assembled nanoparticles was investigated.
Methods: Doxorubicin, an antitumor drug, was trapped in the nanoparticles to explore their drug-release behavior. The drug-loa...
