Solvents-Induced Structure Transitions in Copolymer Films

Abstract:

Structure transitions induced by selective solvents in diblock copolymer films are investigated by density functional theory. By changing the selectivity and the packing fraction of selective solvents, the disorder-lamellar transition, the position switched lamellar phase transitions and the reentrant transitions are observed. Phase diagrams are constructed to clarify these effects. The results provide an effective way to control the transitions between the different microstructures.
