Influence of incorporation carbon nanoparticles CNP on the mechanical properties of polystyrene composite

Polymer nanocomposites have recently received a lot of attention as they are anticipated to be used in a variety of applications. In this study, the effect of adding carbon nanoparticles to polystyrene and using Injection molding technique are investigated. The impact of adding different weight fractions of carbon nanoparticles (CNP) on tensile properties, impact strength and hardness performance of polystyrene polymer were measured. Tensile and impact strength increased with the addition of nanoparticles (CNP). The polymer composites with 0.025 wt.% CNP demonstrated maximum tensile and impact strength compared to pure polystyrene. Also, the maximum value of hardness appeared at 0.1 wt.% of CNP finally cracks are found in higher CNP concentration compared with lower percentages of CNP.
