Effect of silane crosslinking and Silicon carbide nanoparticles on thermal and permeability properties of ethylene butene copolymer

The target of the present study is to investigate the effect of Silicon carbide (SiC) nanoparticles and silane crosslinking on the thermal stability and oxygen permeability of ethylene butene copolymer (EBC). First EBC was silane grafted then nanocomposites with 3 and 7 phr of SiC were prepared. The samples were crosslinked in 70°C water for 48 hours. TGA results showed that crosslinking and addition of SiC nanoparticles increased the thermal stability of EBC. Oxygen permeability increased by silane grafting. However crosslinking and presence of SiC nanoparticles reduced the oxygen permeability significantly
