The oxygen barrier properties of composite materials, consisting of a LDPE substrate coated by a thin layer of nanostructured hybrid organic/inorganic materials based on SiO2 and polyethylene-polyethylene glycol (PE-PEG) block copolymers, obtained via a sol-gel technique have been characterized at 35°C and 50°C. A significant decrease (25-40%) of the oxygen transfer rate has been observed for coated samples with respect to bare substrate both at 35°C and 50°C.
