CONFINEMENT-INDUCED PHASE TRANSITION OF ASYMMETRIC DIBLOCK COPOLYMER IN SOLUTION

摘要：

Confinement of diblock copolymers between parallel solid walls, or in a thin film, has been extensively studied.1-4 The presence of a surface or interface from the confinement can strongly influence the microdomain morphologies and the kinetics of microdomain ordering of block copolymers. Relatively little work has been done on the morphology of asymmetric block copolymer thin films until recently.3,5 Moreover, there has been little consideration of the self-assemblies of block copolymers in dilute solution in confined systems, which are of interest in many biological systems. The phase behavior of block copolymer in dilute solution may be very different from that in the bulk. A hard surface or interface will induce polymer depletion, which can lead to local concentration gradients and solution phase separation under the appropriate conditions.6,7
