From: A unique thermo-induced gel-to-gel transition in a pH-sensitive small-molecule hydrogel
(a) Chemical formula of C18ADPA. (b) Pictures of 2% pH = 5.37 hydrogel at 25 °C and 50 °C together with its transmittance data during successive cooling-heating cycles. (c) Rheological data during successive cooling-heating cycles (strain = 0.5%; angular frequency of ω = 10 rad/s). In (b) and (c), the waiting time after a temperature increase was about 2 min and after a temperature decrease was about 5 min.
