Fig. 12. Relative swelling of microphase-separated self-oscillating gel and poly(NIPAAm-co-
Ru(bpy) 3 ) gels, (Lt-L 0 )/(Le-L 0 ), in the solution of 5 mM Ce(SO 4 ) 2 , 0.894 M HNO 3 at 18 °C as
functions of the time t elapsing after changing the solution. Lt, L 0 and Le, are the lengths of
the gel at t = t, initial state and equilibrium state. (□) microphase-separated self-oscillating
gel; (■) poly(NIPAAm-co-Ru(bpy) 3 ) gel. S. Maeda et al., Peristaltic motion of polymer gels.
