Unique Gelation Behavior of Cellulose in NaOH/Urea Aqueous Solution
Jie Cai,Lina Zhang +1 more
TL;DR: The gel having been formed did not dissolve even when cooled to the temperature of -10 degrees C, at which it was dissolved previously, therefore, this indicates that either heating or cooling treatment could not break such stable gels.
