Abstract

Glass transition temperature of polyetherimide (PEI) thin films andnanoporous PEI samples was investigated using differential scanningcalorimetry. In both of these systems, the glass transition temperaturedecreased with respect to the bulk value. In the nanoporous system, scanningelectron microscope images were used to characterize pore size distribution,and Monte Carlo simulations were performed to calculate the nearest neighborpore-to-pore distances. Pore-to-pore distances and thin film thicknessvalues were used to establish a quantitative analogy between thin films andnanoporous system.
