Polystyrene/sepiolites nanocomposite foams: Relationship between composition, particle dispersion, extensional rheology, and cellular structure

The main objective of this work is to analyze how the cellular structure of foamed polystyrene based (PS) nanocomposites, produced by gas dissolution foaming, is affected by the extensional rheological behavior of the polymer matrix and by the dispersion degree of the particles. These composites have been produced with different types of natural and organomodified sepiolites and with different contents of these particles. The extensional...
