摘要：

A gravimetric method was used to study the sorption and diffusion of supercritical carbon dioxide in a temperature range from 40 degrees C to 80 degrees C and a pressure range from 8.0 to 18.0 MPa in a biodegradable polymer, namely poly(butylene adipate-co-terephthalate) (PBAT). The PBAT presented Fickian behavior and Fick's diffusion model was applied to determine the amount of carbon dioxide present in the samples after a predetermined exposure time as well as the diffusion coefficients. The variations of diffusion coefficients of CO2 for the sorption under supercritical conditions and desorption at ambient conditions as well as equilibrium sorption amounts of CO2 with variations of pressure and temperature were determined and compared.
