The miscibility of chitosan/poly(ethylene oxide) (CS/PEO) blends was investigated by a combination of experiment and molecular simulation. Results from X-ray diffraction (WAXD) and thermal analysis (DSC) suggest that the maximum miscibility was seen at the PEO weight fraction (wPEO) =0.2; the optimum stoichiometric ratio for CS and PEO functional groups. The change in vibrational frequencies from...
The miscibility of Chitosan (CS) and poly(ethylene oxide) (PEO) in their blends and the effect of K + and Ca 2+ doping on the CS/PEO interaction have been investigated in this work. CS and PEO appeared to be miscible and the DSC analysis suggested the Flory–Huggins interaction parameter χ AB to be −0.21. Doping of K + and Ca 2+ into the CS/PEO blend matrix enhanced...
