Phase Separation in Poly(dimethylsiloxane) Films Induced by Physical Crosslinking:Unusual Surface Morphology Due to Associative Polymer,Interfacial Energy,and Confinement Effects

摘要

Phase separation behavior and surface morphology effects in thin and ultrathin polymer films are of special interest for a variety of applications and fundamental investigations.Surface energy,interfacial energy between polymer and substrate,confinement effects,and the thermodynamic interactions between different polymers play critical roles in determining the phase behavior and surface morphology.
