Methoxy poly(ethylene glycol)-grafted chitosan (PEG-g-CS) was synthesized by mild Michael addition reaction of chitosan and methoxy polyethylene glycol monoacrylate. The chemical structure and degree of substitution (DS) of chitosan derivative were studied by FT-IR and 1 H NMR. Blend nanofibers of PEG-g-CS and poly(ethylene oxide) (PEO) were successfully fabricated by electrospinning and characterized...
