FIG. 1.

Equilibrium morphologies (left) and the corresponding scattering patterns (right) in thin films of ABA/AB copolymer blends with different AB compositions [(a) , (b) , and (c) ].

Image of FIG. 2.
FIG. 2.

The collective structure factor profiles of ABA/AB copolymer blends with three different AB compositions (, 0.5, and 1).

Image of FIG. 3.
FIG. 3.

Monomer density profiles of ABA/AB copolymer blends with the composition of AB fixed at 0.5. The squares, circles, and triangles represent data of the overall monomers, the monomers in diblock copolymers, and the monomers in triblock copolymers, respectively.

FIG. 4.

The plots of the lamellar spacing vs the diblock copolymer composition . Squares and circles denote the values obtained from monomer density profiles and structure factors, respectively.

Image of FIG. 5.
FIG. 5.

(a) The evolution of the ODT order parameter with at different diblock copolymer compositions . (b) The ODT phase diagram constructed by plotting vs . The squares and circles denote the lower critical points and the upper critical points , respectively.

FIG. 6.

The plots of the number of nearest interaction pairs between monomers A and B averaged over each chain vs at different diblock copolymer compositions .

Image of FIG. 7.
FIG. 7.

The plots of mean square radius of gyration of two types of copolymers as a function of at different diblock copolymer compositions [(a) diblock copolymer and (b) triblock copolymer].

Image of FIG. 8.
FIG. 8.

The histogram distribution of at and . The squares, triangles, and circles represent the data from three parallel samples.

Image of FIG. 9.
FIG. 9.

The plot of the fraction of bridge chains for triblock copolymers vs diblock copolymer composition for ABA/AB copolymer blends with fixed at around 65.
