© 2014 Elsevier B.V.This paper continues research on the physicochemical features of nanocomposites of poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) and fullerene C60 with the purpose of using them as a selective layer of composite membranes in pervaporation coupling esterification of acetic acid with ethanol to produce ethyl acetate. The C60-PPO/MFFC composite membranes containing up to 3wt%C60 were prepared in this work. SEM was employed in visualizing the internal morphology of the membranes. The nature of the interaction between PPO and C60 molecules in composite was studied by NMR. TG analysis reveals the fact of increasing thermal destruction point of the membrane due to certain structural changes of the PPO matrix upon incorporation of the C60 molecules. Transport properties of composite membranes with a selective layer containing up to 3wt%C60 were studied in the pervaporation of the quaternary mixture: ethanol, acetic acid, ethyl acetate, and water in order to identify the availability of their use in
