Influence Of Processing Induced Morphology On The Performance Of PP Injected Intricate Pieces Modified With MWCNT As A Painting Aide

Carbon nanotubes are currently added to polymers avoid extra-stages in the electrostatic painting process. However, attained particle network after processing a final part could affect mechanical properties and thermal stability of nanocomposites. It is then important evaluate not only functional properties, but also overall performance these pieces. In this work, boxes polypropylene (PP) modified with multi-walled carbon (MWCNT) were injection molded. Morphology induced by was characterized at different locations moldings correlate influence in-homogeneities flow pattern molded boxes. PP/MWCNT presented better aesthetic quality markedly than pure PP. confirmed that nanocomposite has high dielectric permittivity, low losses relatively good DC conductivity. Regarding MWCNT slight improvement flexural elastic modulus. Although fracture initiated practically same loading levels for both materials, propagation energy deteriorated presence. Differences electrical behavior found trough out pieces as result distinct orientation distribution. concluded great on parts performance.
