Preparation and characterization of biodegradable chitosan and methoxy poly(ethylene glycol)-b-poly (ε-caprolactone) blend homogeneous films
Blend homogeneous films of chitosan and water-soluble methoxy poly(ethylene glycol)-b-poly(ε-caprolactone) (MPEG-b-PCL) diblock copolymer with different blend ratios were prepared by aqueous solution blending method. The water-soluble MPEG-b-PCL was synthesized using MPEG with molecular weight of 50...

| description | Blend homogeneous films of chitosan and water-soluble methoxy poly(ethylene glycol)-b-poly(ε-caprolactone) (MPEG-b-PCL) diblock copolymer with different blend ratios were prepared by aqueous solution blending method. The water-soluble MPEG-b-PCL was synthesized using MPEG with molecular weight of 5000 g/mol and stannous octoate as the initiating system. The molecular weight of MPEG-b-PCL obtained from ¹H-NMR was 5800 g/mol. FTIR spectra of the blend films showed that there were intermolecular bonds between chitosan and MPEG-b-PCL. Thermal properties of the blend films strongly depended on the blend ratios. Scanning electron micrographs indicated that the blend films were homogeneous films. However, roughness of the blend films increased whereas transparency and moisture uptake decreased upon increasing the MPEG-b-PCL blend ratios. |
