Dispersity and asymmetric interactions with substrates facilitate co-existence of cylindrical and lamellar domains in thin films of diblock copolymers.
Significance and Impact
Work establishes dispersity as an important parameter in realizing co-existing nanoscale domains and for tailoring properties of thin films containing diblock copolymers.
