Remarkably Strengthened microinjection molded linear low-density polyethylene (LLDPE) via multi-walled carbon nanotubes derived nanohybrid shish-kebab structure

In this work, linear low-density polyethylene (LLDPE) nanocomposites with different loading levels of multi-walled carbon nanotube (MWCNTs) were prepared by microinjection molding. Interestingly, a similar network structure featured with oriented nanohybrid shish-kebab structure was formed in all the LLDPE/MWCNTs composites. Importantly, the composites with improved strength and modulus in parallel with enhanced toughness were obtained. For example, the tensile strength, modulus and toughness of the composites with 1 wt% MWCNTs were increased by 64.1%, 100% and 134.6%, respectively. This work offers a simple approach to achieve high-performance composites molded by microinjection molding (MIM) together with nanohybrid shish-kebab structure.
