- ... In this work a gel was formed by complexation of two natural polyelectrolytes, chitosan and xanthan. Changes in the hydrogels rheological properties have been studied in terms of hydrogel concentration (7-10% w/w), chemical media used for the hydrogel dispersion, and 'test lag time'; i.e., the time between hydrogel dispersion in the chemical media and the start of the rheological test (up to 390 m ...
