Impact of Domain Size on the Length Scale of Local Glass Transition Perturbations Caused by an Immiscible Glassy-Rubbery Interface

{{output}}
The depth-dependent profile in local glass transition temperature Tg(z) was measured by pyrene fluorescence within 75 nm thick glassy polystyrene (PS) domains either capped by 600 nm thick poly(n-butyl methacrylate) (PnBMA) layers or exposed to the free surfac... ...
