چکیده:

Permeation models for nanocomposite polymeric membranes (NCPMs) are discussed. Two new models are proposed for the effective permeability of NCPMs. These modelstake into account the presence of interfacial layer at the surface of the nanofillers. The impact of two important phenomenavoidscreation and increasing free volume- in this layer is investigated. The efficiency of the proposed models for prediction of experimental data by our experimental data andfive sets of others experimental data are shown. Also the superiority of these models is verified by comparing with two phase Bruggeman model and Bruggeman model in limit which is the only presented model for NCPMs
