| Résumé: | In this work, the effect of graphene oxide (GO) and
its derivatives on the mechanical, thermal and morphological
properties of nanocomposites based on polypropylene/
ethylene-propylene rubber (PP/EPR) were investigated. In order to achieve a better dispersion of the nanofiller and to enhance its interaction with the polymer matrix, amine and alcohol grafted polypropylene were used as compatibilizers.
These compatibilizers were synthesized by the reaction of
polypropylene-grafted anhydride maleic (PP-g-MAH) with
1,12-dodecanediamine and 1,12-dodecanediol, respectively
in the presence of dicumyl peroxide (DCP) by melt mixing.
The nanocomposites were prepared via melt blending
masterbatch process using Brabender mixer. The addition of
functionalized GO and compatibilizers improved the tensile
strength and Young’s modulus of PP/EPR nanocomposite.
While the elongation and Izod impact strength were adversely
affected. Furthermore, the TGA analysis showed that the incorporation of GO and compatibilizers improve significantly
the thermal stability. SEM micrographs of the fractured surfaces of the nanocomposites revealed a good dispersion of
functionalized GO in the polymer matrix |
