Modeling sorption kinetics of carbon dioxide in glassy polymeric films using the nonequilibrium thermodynamics approach / Vito Carlà in Industrial & engineering chemistry research, Vol. 48 N° 8 (Avril 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 8 (Avril 2009) . - pp. 3844–3854 Titre : Modeling sorption kinetics of carbon dioxide in glassy polymeric films using the nonequilibrium thermodynamics approach Type de document : texte imprimé Auteurs : Vito Carlà, Auteur ; Yazan Hussain, Auteur ; Christine Grant, Auteur Année de publication : 2009 Article en page(s) : pp. 3844–3854 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Glassy  polymers  Nonequilibrium  thermodynamics  One-dimensional  transport  model  Carbon  dioxide  Sorption−diffusion−relaxation  model Résumé : The nonequilibrium thermodynamics of glassy polymers (NET-GP) approach ( Macromolecules 2005, 38, 10299.) has been applied to the development of a one-dimensional transport model aimed at describing the kinetics of sorption and dilation of polymeric films in supercritical carbon dioxide. The NET-GP model was combined with a simple rheological constitutive equation to build a sorption−diffusion−relaxation model able to describe mass uptake and swelling kinetics of polymeric films in contact with carbon dioxide over a wide range of pressures and temperatures. The model calculations are compared with data on mass sorption kinetics for CO2 in supported glassy poly(methyl methacrylate) (PMMA) films, measured in a high-pressure quartz crystal microbalance (QCM).
