Abstract :
Polypropylene composites with different contents of multiwalled carbon nanotubes (MWCNT) were microinjection molded to investigate the influence of melt temperature and injection velocity on the final mechanical properties. Therefore, samples of various MWCNT loadings from 1 wt% to 5 wt% were prepared by diluting commercial masterbatches. Microinjection molding was used to prepare micro tensile bars under different processing conditions. The nano composites expose mechanical properties significantly influenced by nanotube loading, injection velocity and melt temperature.
