Dynamic storage modulus G′ (solid triangle and solid square) and loss modulus G″ (hollow symbols) of a 1.0 wt% agarose sample containing a concentration of PEO₁₁₃-b-PDPAEMA₃₁ micelles of (a) 0, (b) 0.5, (c) 1.0, (d) 2.0, and (e) 5.0 mg/g. The samples were first cooled from 25 to 2 °C (shown in red square) and then equilibrated at 2 °C for 25 min. The whole process took about 33 min. The samples were then heated to 60 °C (shown in black triangle). A cooling/heating rate of 3 °C/min, a strain amplitude of 1.0 %, and a frequency of 1 Hz were used.
