Figure 6.
The effect of the rate of solvent uptake (dϕ/dt) on lateral ordering for two different values of ϕs. AFM images of films with different swelling rates for film reaching maximum ϕs = 0.8 (a–c) and maximum ϕs = 0.86 (d–f). Fourier transforms are shown in the inset. (g) Solvent annealing profile for (a–c) as a function of ϕs and swelling ratio at different swelling rates. (h) Correlation length ξ at different swelling rates, indicating that the slower swelling rate improves the microdomain correlation length. All scale bars are 1 μm.
