Preparing Xanthan-Chitosan Composites in Glycerol

摘要

Anionic xanthan (X) and cationic chitosan (C) form xanthan- chitosan (X+C) complexes by electrostatic attraction in an aquatic environment where concentration of either of the polysaccharides does not exceed 2.5 wt %. Covalently bonded xanthan-chitosan (X-C) composites were prepared in dry glycerol with concentration of either of the polysaccharides in the range 0.025 to 50% weight.
