Fluctuation Effects on the Order–Disorder Transition of Symmetric Block Copolymers Mixed with Random Copolymers or Homopolymers
Blending block copolymers (BCPs) with polymeric additives provides a direct route to controlling microphase separation, yet how such additives alter composition fluctuations remains incompletely understood. Here, we examine the order–disorder transition (ODT) in symmetric AB diblock copolymers mixed with either neutr...
