Associating phenomena in highly acetylated chitosan gels

The effect of covalent glutardialdehyde crosslinking on chitosans with different chemical composition was examined. Large differences in the dynamic storage modulus was observed between chitosan gels with different degrees of acetylation. Contrary to what would be expected from chemical consideratio...

Description
Summary:The effect of covalent glutardialdehyde crosslinking on chitosans with different chemical composition was examined. Large differences in the dynamic storage modulus was observed between chitosan gels with different degrees of acetylation. Contrary to what would be expected from chemical considerations, an increased G′ was found within gels high in N-acetyl glucosamine residues. Results presented suggest that hydrophobic interactions are involved in the stabilization of highly acetylated chitosan gels.
