Multiple patterns of diblock copolymer confined in irregular geometries with soft surface |
(a)–(c) Morphologies of diblock copolymer by changing the fraction of B block with h = 2.46 R g and L = 1.23 R g; (d)–(f) morphologies of diblock copolymer by changing the fraction of B block with h = 4.92 R g and L = 1.23 R g. From left to right the fractions of B component are f B = 0.25, f B = 0.45, and f B = 0.75, respectively. |
