Abstract
Evidence suggests that the fragility (m) of glass formation both underpins and is sensitive to nanoconfinement effects on the glass transition. Here we present data indicating that nanoconfinement-induced changes in m of freestanding films emerge from a dominance of finite-size-driven fragility suppression over interfacial fragility enhancement.
