Rheological properties of mPEG-g-chitosan: (a) Phase angle, storage and loss moduli as a function of temperature for 1.5 wt% mPEG-g-chitosan in 1× PBS; (b) Phase transition diagrams of mPEG-g-chitosan in the presence of different salt concentrations (DI water, 1× PBS, 10× PBS) with different solute concentrations (mPEG-g-chitosan at 0.5, 1.0, 1.5, 2.0, and 2.5 wt%). For 2a, frequency: 1Hz; strain: 10%; temperature ramping: 1°C/min.
