Key Points

  • To investigate the phase behavior of strongly segregating polystyrene and polydimethylsiloxane blends under confinement.
  • Examined phase behavior in thin films of PS/PDMS blends
  • Analyzed the effect of confinement on lateral phase separation
  • Identified scaling relations related to film thickness
  • Lateral phase separation is completely suppressed below a critical thickness
  • Identified critical thickness for phase behavior changes
  • Observed significant differences in confinement-controlled phase behavior

Abstract

We report confinement-controlled scaling relations governing the phase behavior of strongly segregating polystyrene (PS)/polydimethylsiloxane (PDMS) blends in thin films. Below a critical thickness h c , lateral phase separation is completely suppressed,...
