Roles of hydrophobic interaction in a volume phase transition of alkylacrylamide gel induced by the hydrogen-bond-driving alkylphenol binding

Article Abstract:

A degree of the binding of alkylphenols to N-alkylacrylamide gel increased transitionally to induce the volume phase transition of gel. The former binding was analyzed with the Hill equation applicable to the cooperative binding and the latter binding with the Brunauer-Emmett-Teller (BET) equation applicable to the multilayer adsorption.

Salt effect on elastic properties of shrunken N-isopropylacrylamide gel

Article Abstract:

A partition of NaCl between the gel and the solution outside the gel was examined. The effect of NaCl molecules on the state of clustered molecules was detected as a change in the transition enthalpy, which was obtained by differential scanning calorimetry measurements.
