Keywords: Glassy polymers Diffusion Membranes for gas separation Transport properties Thermodyanamic modelling

The main research activity is devoted to the study of thermodynamic and transport properties of low molecular weight species in polymer based systems, from both the experimental and the modeling point of view. The experimental work is carried out by means of different apparatuses for the characterization of permeation and sorption of gases, vapors and liquids in polymeric materials in different conditions of temperature, pressure and composition. The modeling activity regards the theoretical analysis of thermodynamic properties of polymer/penetrant systems above and below Tg, with particular care devoted to the case of nonequilibrium behavior of glassy polymers. The study of the kinetics of diffusion is also carried out by means of specific models for gas and vapor permeation in complex systems, such as nanocomposites, semicrystalline polymers or polymer blends or copolymers; as well as the analysis of anomalous diffusion in swelling glassy polymers.
