In this study, The volume oscillation of the microphase‐separated, self‐oscillating gel above the volume phase transition temperature is discussed. The self‐oscillating gel is composed of N‐isopropylacrylamide (NIPAAm) with a metal catalyst for the Belousov–Zhabotinsky (BZ) reaction, which is known as the oscillating reaction. The influence of temperature on the period and the self‐oscillating behavior is clarified. The volume change of the gel is explained by a change of the Flory–Huggins interaction parameter, χ, which is induced by the hydration and dehydration of the polymer chain due to a valance change of the metal catalyst (Ru(bpy)32+ ↔ Ru(bpy)33+) below the volume phase‐transition temperature. In contrast, the volume change of the gel is explained by a change of the Donnan osmotic pressure.
