CO2 permeability of polystyrene nanocomposites and nanocomposite foams / Zhihua Guo in Industrial & engineering chemistry research, Vol. 47 N° 23 (Décembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N° 23 (Décembre 2008) . - p. 9636–9643 Titre : CO2 permeability of polystyrene nanocomposites and nanocomposite foams Type de document : texte imprimé Auteurs : Zhihua Guo, Auteur ; L. James Lee, Auteur ; David L. Tomasko, Auteur Année de publication : 2009 Article en page(s) : p. 9636–9643 Note générale : Chemistry engineering Langues : Anglais (eng) Mots-clés : CO2  permeability  Polystyrene  Nanocomposite Résumé : Steady state permeability coefficients P of carbon dioxide (CO2) in polystyrene (PS) and PS nanocomposites and their corresponding foams at 0.10 MPa (gauge pressure) and three different temperatures were measured. Permeability coefficients of foams are about 1 order of magnitude higher than those of corresponding plates. Three PS nanocomposites were used: PS + 5% 20A (treated nanoclay provided by Southern Clay), PS + 5% CNFs (carbon nanofibers), and PS + 5% MHABS (nanoclay treated with 2-methacryloyloxyethylhexadecyldimethylammonium bromide). For both plates and foams, the permeability coefficient decreases considerably with addition of nanoparticles. Foam structure is shown to play a more important role than nanoparticles in determining the permeability coefficient values for nanocomposite foams.
