Abstract

Bilayer and trilayer polymer films are characterized by fluorescence techniques sensitive to glass transition temperature, physical aging, and diffusion. We show that the glass transition temperature (Tg) of 14-nm-thick polystyrene (PS) layers can be strongly coupled to that of bulk underlayer films of different polymers, allowing its Tg to be varied from 318 K to 418 K. We also show that the translational diffusion coefficient of small dye molecules within PS can decrease as much as an order of magnitude with confinement.
