Figure 5.7: Anti-symmetric segment density profiles of the A block (solid black curve)
and B block (dashed black curve) of the copolymer for (a) H = 14σ, (b) H = 16.4σ, and
(c) H = 20.4σ. For the diblock copolymer, N = 8 and e∕kT — 0.289. For surfaces, e_w∕kT
= 0.1.

blocks of the copolymer at different film thickness. At H = 14σ or film thickness of
13σ, there are lɪ lamella of both A and B where half lamellae of A and B are at each
of the two surfaces. The lamellar period is smaller than the preferred lamellar period
