Figure 2
(a) SAXS and (b) WAXS profiles of st-PMMA/toluene solution for [st-PMMA] from 0.05 to 0.4 M. (c) Concentration-dependent variation of structural parameters (ξ, Rg,hc and Rg,HIC) derived from SAXS model fitting in (a). (d) Illustration of structural evolution in the reversible sol-to-gel transition of the st-PMMA/toluene system. Temperature-dependent (e) SAXS and (f) WAXS profiles of st-PMMA/toluene at [st-PMMA] = 0.4 M. (g) Variation of ξ, Rg,hc and Rg,HIC derived from the SAXS model fitting in (e) during the gel-to-sol transition process. |
