“…Figure c displays 1/ I (0) vs 1/ T for G -102 solutions with various polymer concentrations at C Cl = 1.0 M, demonstrating the linear relationship between 1/ I (0) and 1/ T . As temperature approaches the spinodal temperature ( T s ), I (0) becomes divergent as 1/ I (0) ∼ (1/ T s − 1/ T ). ,,, Therefore, T s is determined by linear extrapolation to the x -intercept of 1/ I (0), leading to T s = 3, 20, 26, 23, 17, and 5 °C for 1, 2.5, 4.5, 8, 11, and 15 wt % G -102 solutions, respectively, at C Cl = 1.0 M (also see Figure S18 for the other G solutions). In the Section , T s obtained from all G polymers as a function of c and C Cl are used to construct the spinodal curves.…”
