Reinforcement of shape-memory poly(ethylene-co-vinyl acetate) by carbon fibre to access robust recovery capability under resistant Condition`
关键字：Smart materials, Carbon fibresPolymer-matrix composites, Shape memory polymer
Poly (ethylene-co-vinyl acetate) (EVA), as one of commercial polymers, has been used early to fabricateshape-memory polymers (SMPs). However, its low recovery stress restricts the potential applications insome tough conditions due to its high ?exible feature. Herein, we developed a series of EVA-basedcomposites (cEVA/CF) with remarkably enhanced recovery stress both in free-state and resistant con...

Poly(L?lactic acid)-block-poly(butylene succinate-co-butylene adipate) Multiblock Copolymers: From Synthesis to Thermo-Mechanical Properties
关键字：biodegradable, multi-block copolymer, chain extension, chain coupling
Multiblock copolymers poly(L-lactic acid)-block-poly(butylene succinate-co-butylene adipate)s (abbr. P(LLA-mb-
BSA)s) are synthesized via a polycondensation/chain extension/coupling method using binary chain extenders. A poly(L-lactic acid) (PLLA) prepolymer synthesized via direct melt polycondensation of L-lactic acid is rapidly chain extended with a bis (2-oxazoline) to form hydroxyl t...

Grafting of telechelic poly(lactic-co-glycolic acid) onto O2 Plasma Treated Polypropylene Flakes
关键字：polypropylene; telechelic poly(lactic-coglycolic acid); oxygen plasma; grafting
In this work, we described a facile approach to preparing polypropylene (PP) surface functionalized with telechelic poly(lactic-co-glycolic acid) (HOPLGA-COOH). The PP flakes were first treated with oxygen plasma and then grafted with different molecular
weight PLGA (Mw ? 50, 100, and 300 K) in dry dichloromethane solution with the addition of phosphorus pentachloride (PCl...

B-11 3Q MAS NMR Study on Glucose-Responsive Micelles Self-assembled from PEG-b-P(AA-co-AAPBA)
关键字：B-11 3Q MAS NMR, coordination, glucose-responsiveness, micelles, self-assembly
Phenylboronic acid (PBA) based glucose-responsive materials have attracted great interests in recent years for developing insulin delivery systems. It is desired to obtain PBA based materials that can response to glucose under physiological pH and understand the mechanism. By using B-11 triple-quantum magic-angle spinning nuclear magnetic resonance (B-11 3Q MAS NMR) measurements, the glucose-res...

Surface modification of poly(styrene-b-(ethylene-co-butylene)-b-styrene) elastomer via UV-induced graft polymerization of N-vinyl pyrrolidone
关键字：Styrenic block copolymers, UV-induced graft polymerization, N-vinyl pyrrolidone (NVP), Hemocompatibility
Poly(N-vinyl pyrrolidone) (PNVP) was covalently grafted onto the surface of biomedical poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) elastomer via a technique of UV-induced graft polymerization combined with plasma pre-treatment. The surface graft polymerization of N-vinyl pyrrolidone (NVP) was confirmed by ATR-FTIR and XPS. Effect of the parameters of graft polymerization, i...

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...
