Influence of Carbon Black (CB) on Mechanical Behaviour and Microscopic Analysis of Poly-propylene (PP)/ Acrylonitrile-butadiene- styrene (ABS) Nanocomposites

Abstract

Composite materials allow designing materials that may combination of mechanical properties similar to those high load bearing materials. For advance mechanical properties of material polypropylene (PP) as a polymer, acrylonitrile-butadiene styrene (ABS) as rubber phase copolymer and filler material as carbon black (CB) are used to prepare blending of PP/ABS and formation of nanocomposites. Nanocomposite is prepared using twin screw extruder via injection molding. For characterization of polymer nanocomposites, microscopic analysis and mechanical properties are studied. For microscopic analysis to understand the morphology, the scanning electron microscopy (SEM) is used. Further, for mechanical behaviour, tensile test and impact test are carried out. As carbon black has comparatively unique structure and properties became an important group of filler material which offered improvement mechanical properties. The existing polymer blend is modified with the nano filler material; which exhibits improved morphological and mechanical properties having cost efficient application. These mechanical and morphological results depicts PP/ABS (80/20) blends in presence of CB improves the results. It is found that 2.5 wt % of CB gives better tensile properties and 5wt % CB showing better improvement in Impact strength.
