摘要：
Adding triblock copolymers to hydrophilic films is an option to improve the functional properties and water resistance under high equilibrium relative humidity (RHeq) environments. Sorption isotherms of corn starchchitosan based films added with triblock copolymers (L64 and P123) measured at 4, 20, and 36 degrees C were fitted using the Guggenheim-Anderson-De Boer equation. Thermodynamic analysis allowed allocating the minimum integral entropy value between 0.09 and 0.50 of water activity. The compensation enthalpy-entropy showed that the entropy driven the process at low water activities (0.10- 0.33) and the enthalpy driven the water sorption at high water activities ( 0.33- 0.90).
