Analysis of Gas Sorption in Glassy Polymers with the GAB Model: An Alternative to the Dual Mode Sorption Model
Original language description
The suitability of the Guggenheim-Anderson-De Boer (GAB) model for the parameterization of gas sorption isotherms and their dependences on temperature is explored. The GAB model implies that molecules adsorb on inner surfaces of the polymer in multilayers, which contrasts with the assumptions of the classical Dual Mode Sorption (DMS) model which implies the simultaneous occurrence of Henry-like dissolution and Langmuir's case I adsorption. The GAB model shows similar efficacy of the parameterization ofthe gas sorption isotherms in polymers as the DMS model. The isosteric heat of adsorption shows clear dependence on relative surface coverage for carbon dioxide sorption in cellulose acetate, polyethylene terephthalate, and the first polymer of intrinsicmicroporosity (PIM-1), thus allowing for the occurrence of adsorption multilayers.
