Chitosan-PEG : an approach for a self supramolecular derivative

Abstract

A self supramolecular structured chitosan is designed and prepared by introducting polyethyleneglycol monomethylether onto low molecular weight chitosan chain. The packing structure of the product observed from wide angle X-ray diffraction demonstrates the dramatically change to amorphous like structure. The product obtained shows high swelling ability in water. The inclusion property of the product obtained for potassium ion is studied by UV-VIS spectophotometer. The studies on inclusion phenomena clarify that the inclusion capacity for potassium ion of the product obtained is better than the low molecular weight chitosan.
