Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A method of modifying a poly(ethylene furanoate) film, the method comprising: a) plasticizing a poly(ethylene furanoate) (PEF) film by contacting the PEF film with (1) water at a temperature at or below 25° C. for a time period from about 0.25 h to about 40 h or (2) at least about 90% relative humidity air at a temperature at or below 25° C. for a time period from about 1 h to about 40 h; and b) subjecting the plasticized PEF film to a dynamic strain oscillation within the PEF linear viscoelastic range. 2. The method of claim 1 , wherein the PEF film is contacted with at least about 90% relative humidity air at a temperature at or below 25° C. for a time period from about 1 h to about 25 h. 3. The method of claim 1 , wherein the PEF film is contacted with water at a temperature at or below 25° C. for a time period from about 0.5 h to about 25 h. 4. A poly(ethylene furanoate) (PEF) film modified according to the method of claim 1 . 5. A method of modifying a poly(ethylene furanoate) film, the method comprising: a) plasticizing a poly(ethylene furanoate) (PEF) film by contacting the PEF film with (1) water at a temperature greater than 25° C. for a time period from about 0.5 h to about 25 h or (2) at least about 90% relative humidity air at a temperature greater than 25° C. for a time period from about 1 h to about 25 h; and b) subjecting the plasticized PEF film to a dynamic strain oscillation within the PEF linear viscoelastic range. 6. A poly(ethylene furanoate) (PEF) film modified according to the method of claim 5 . 7. A method of modifying a poly(ethylene furanoate) film, the method comprising: a) plasticizing a poly(ethylene furanoate) (PEF) film by contacting the PEF film with at least about 95% relative humidity air at a temperature at or below 25° C. for a time period from about 0.25 h to about 50 h; and b) subjecting the plasticized PEF film to a dynamic strain oscillation within the PEF linear viscoelastic range. 8. A poly(ethylene furanoate) (PEF) film modified according to the method of claim 7 . 9. A method of modifying a poly(ethylene furanoate) film, the method comprising: a) plasticizing a poly(ethylene furanoate) (PEF) film by contacting the PEF film with at least about 95% relative humidity air at a temperature greater than 25° C. for a time period from about 0.5 h to about 50 h; and b) subjecting the plasticized PEF film to a dynamic strain oscillation within the PEF linear viscoelastic range. 10. A poly(ethylene furanoate) (PEF) film modified according to the method of claim 9 .
