Charpy Impact Resistances of Carbon Nanotubes Reinforced High Density Polyethylene Nanocomposite Materials

Abstract

Abstract-In this study, Multiwall Carbon Nanotubes (MWCNT) reinforced High Density Polyethylene (HDPE) materials were used. Mechanical properties of the samples reinforced with Carbon Nanotubes at weight ratios of 1%, 3% and 5% were investigated. Reinforced samples were compared to samples produced with pure High density Polyethylene. Samples were produced by plastic injection method. The samples were then subjected to experiments and impact resistance values were measured in accordance with ASTM D6110 standards. Also Thermogravimetric Analyses (TGA) was performed for and Multi-Wall Carbon Nanotubes within the High Density Polyethylene. At the end of the study, it was observed that impact resistance decreased with increasing carbon nanotube reinforcement amount. Impact resistance of samples produced by means of plastic injection was decreased by 35% comparing with samples produced from pure HDPE. These results were explained with the fact that structures of composite materials were transformed to a tougher and fragile phase. In the TGA investigations, it was seen that mass loss breakdown temperature and melting point temperature increased by MCWNT ratio in the composite samples.

Mechanical and physical characterizations of compatibilizer‐free recycled plastics blend composites modified with carbon nanotube and clay nanofiller

“…CNT have gained a huge attention in various fields such as biomedical 17 and electrical 18 owing to their unique structure of tube-shaped allotropes of carbon with ultra-high aspect ratio, 19 remarkable mechanical and electronic properties. 20 For instance, by adding 0.1-2.0 wt% of multiwalled carbon nanotubes (MWCNT) into PP, the mechanical and viscosity properties of the nanocomposites were improved. 15 Fouad et al, 21 has investigated the HDPE/CNT nanocomposites prepared via extrusion blending technique and the findings reported that 4 wt% of carbon nanoparticles to improve storage and Young's modulus and yield strength without affect the melting temperature.…”

“…29 In another study of hybrid CNT/clay nanofillers on immiscible PE/PP blend, the finding reported the selective localization of CNT within the PE phase, while the clay particles showed affinity towards the PP phase, however due to the poor adhesion between PP matrix and the clay, the mechanical properties were degraded. 30 Numerous literatures showed the investigation on single polyolefin incorporated with CNT or nanoclay, 9,10,20,31,32 yet the research work published on polymer blend based nanocomposites without compatibilizer is limited. Based on the recent works by our research group, the rHDPE/rPET blend was used as matrix to incorporate with nanoclay and the focus was placed on the processing parameter factors such as the mixing methods, temperature, and rotation speed.…”
