11. For example, dielectric constants of N-methylacetamide, methyl acetate, and 1,2-dichloroethane are 179.0 at 30 °C, 7.07 at 25 °C, and 10.42 at 20 °C, respectively.
12. 7 was prepared by the substitution of solvent for the polymer gel from ethanol to water. In this work, the hydrogel was obtained from an acetone solution. We have found that the hydrogel obtained from an ethanol solution contains a very small amount of ethanol molecules that can affect the volume phase transition profile.
