Abstract: This disclosure provides an investigation of the kinetic uptake properties of water in amorphous PEF and PET across the entire water activity interval at various temperatures, and also investigates the corresponding equilibrium uptake properties at the same conditions. Uptake data were measured using three independent and complementary methodologies, and excellent agreement was observed among all three methodologies. Accordingly, this disclosure provides for methods of plasticizing poly(ethylene furanoate) film by cold water sorption, and provides a plasticized poly(ethylene furanoate) (PEF) film made according to the disclosed methods. Methods for making thin films of PEF are also provided.
