Tuning the glass transition temperatures of polymers by up to 100℃: equivalence of confinement effects in multilayer films and polymer blends
The glass transition of a polymer occurs when, upon cooling, chains are no longer able to adopt equilibrium conformations on the experimental time scale. This transition from a disordered, rubbery or liquid equilibrium state to&nb...
