Cellular poly(vinyl alcohol) (PVA) hydrogels that exhibit enhanced swelling kinetics from an initial dry state were prepared by freezing and thawing techniques in the presence of NaCl. Gels that were dried immediately after preparation demonstrated a dual-sorption effect upon swelling. Gels that wer
The gelation process of locust bean gum (LBG) aqueous solution has been studied by rheological and calorimetric measurements. The storage modulus of the gel was found to be dependent on repeating cycles of the freezingΓthawing process and freezing speed. When freezingΓthawing was repeated more than
