Cover Story: Isotactic polypropylene (PP) composite drawn fibers were prepared using melt extrusion and high-temperature solid-state drawing. Five different fillers were used as reinforcement agents (microtalc, ultrafine talc, wollastonite, attapulgite, and single-wall carbon nanotubes). Better results are observed using needle-like fillers, such as wollastonite and single-wall carbon nanotubes, since high aspect ratio particles tend to align during the drawing process and, thus, contribute to a more symmetrical distribution of stresses. Competitive and synergistic effects occur among the additives and fillers, such as the antioxidant effect being enhanced by the addition of the compatibilizer, while the antioxidant itself acts as a compatibilizing agent.
