(a) Specific volume of the segmental mixture of PEO and P4VP at 200°C calculated by equation (6)[link], assuming gf = 0.01. (b) Corresponding composition variation of the mass density and electron density of the PEO/P4VP mixture at 200°C. (c) Corresponding electron density profile calculated from an assumed weight fraction profile w4VP(z) shown in the plot. The electron density profile still shows the two-phase characteristic. (d) Specific volume of the segmental mixture of PEO and P4VP at 60°C calculated by equation (6)[link], assuming gf = 0.01. (e) Corresponding composition variation of the mass density and electron density of the PEO/P4VP mixture at 60°C. (d) Corresponding electron density profile calculated from an assumed weight fraction profile w4VP(z). The electron density profile now exhibits a three-phase characteristic with two humps located in the vicinity of the P4VP microdomain.
