Homogeneous synthesis and characterization of chitosan ethers prepared in aqueous alkali/urea solutions
Abstract
The etherification of chitosan dissolved in aqueous LiOH/KOH/urea solutions was conducted for the first time. The structure and solution properties of the chitosan ethers were characterized using FT-IR, NMR, SEC-LLS, elemental analysis, and ζ-potential measurement. Chitosan ethers with different degrees of substitution (DSs) were obtained by adjusting the molar ratio of the etherifying agent to N-acetylglucosamine unit (AGU) of chitosan. The...
