This session is focused on the study of phenomena involving gas diffusion, gas permeability and gas dissolution in polymers. From a scientific point of view, the relationships between molecular architecture, polymer morphology, amount and type of fillers used in the composition, etc and the diffusion rates and amount of gas that can be dissolved in a given polymer is an interesting topic, which is nowadays in the centre of discussion of the scientific community due to the new possibilities offered by nanofillers and bioplastics to control the diffusion rates and solubility limits. From the technical point of view this knowledge is used in important industrial products such as, thin films for packaging of food (barrier properties), stoppers for wine bottles, plastic parts with low permeability to gases, production of microcellular and nanocellular foams for several industrial applications, etc.
This session will deal with any topic related to gas diffusion in polymers but paying special attention on three main areas:
- Gas diffusion and permeability in bioplastics.
- Possibilities offered by fillers and nanofillers to control the permeability in polymer systems.
- Fabrication of microcellular and nanocellular foams via supercritical gas dissolution.
Topics of the Session:
- Production of foams via supercritical gas dissolution
- Gas permeability in polymer thin films.
- Fillers and nanofillers in polymers: Modifying gas permeability
- Gas permeability of bioplastics and composites and nanocomposites based on bioplastics.
- Novel polymers with improved barrier properties.
- Diffusion coefficients in polymeric materials: methods and experimental results
- Diffusion process in polymeric materials: Analytical and FEM modelling.
