Abstract
Polymer layered silicate nanocomposites (PLS) based on clays have been produced in order to rationalise and improve physical and chemical properties of polymeric materials. The interest in the investigation of the thermal behaviour of polymer-clay nanocomposites is due to the fact that several phenomena can take place during heating; one of them is the rearrangement of the layers during high temperature processes [1,2]. The thermal behavior of an intercalated nanocomposite based on poly (ethylene-co-vinyl acetate) (EVA) and organomodified clay (Nanofil 15 and Cloisite 20A) has been studied between room temperature and 350°C (thermal treatment, TT) with different analytical techniques both under inert and oxidative atmosphere as well as under vacuum. Further studies are carried out in order to follow the clays migration during thermal treatments under oxidative atmosphere and its effect on the combustion behavior of the PLS
