Film Formation of Inclusion Complexes between Acetyl-Beta-Cyclodextrin and Chitosan

Abstract:

In this research, the films which were prepared from inclusion complexes (ICs) of acetyl-beta-cyclodextrin (Acetyl-β-CD) with chitosan were characterized and the membrane properties were investigated. Acetyl-β-CD either improved the solubility of chitosan or increased the salt rejection of the membrane. The crystalline ICs, were formed and found on the membrane surface. There were isolated and characterized by scanning electron microscopy (SEM), X-ray diffraction and atomic force microscopy (AFM). The stability and conformation of the inclusion complexes in solvent and limited number of acetyl-β-CD threaded on chitosan molecules were studied and compared the results on a molecular level of the pseudopolyrotaxane.
