The effect of GnP loading and the use of the PP-g- MA compatibilizer were studied. The influence on the mechanical properties of tensile strength, elongation, IZOD impact strength, and melting temperature in PP-homo and PP-copolymer were investigated and compared. Their improvement was observed up to a certain amount, depending on whether it is a homopolymer or copolymer. The PP copolymer has a greater affinity with graphene and the compatibilizer due to the elastomeric comonomer present in the copolymer.852-856openAccessgraphenenanoparticlescopolymerspolypropylenetensile propertiesTexto completo de eventohttps://orcid.org/0000-0002-7968-2117
