Polyolefín/jíl nanokompozity: srovnání mechanických a bariérových vlastností

Abstract

Polyolefin/clay nanocomposites were filled by the series of commercial filler Nanofil. Maleated polyolefins were used for better compatibility between polymer matrix and filler. The morphology and properties were evaluated. The properties of nanocomposites were tested by using mechanical tests and barrier properties. The results of PE/clay nanocomposites showed that the mechanical and barrier properties were not higher than the virgin polymer. However, polyethylene contained filler Nanofil 9 had better mechanical properties in compare with the virgin polymer. PP/clay nanocomposites had higher mechanical properties for both used concentration and PP/Nanofil 9 and 3000 had better barrier properties than the virgin PP.
