Abstract

In the present study, the usability of high-density polyethylene (HDPE) based composites was investigated in medical applications under impact loads. Due to the importance of biocompatibility of composites in medical applications and the body environment, zinc oxide nanoparticles (ZnO) were selected as reinforcements. ZnO nanoparticles are generally safe and have superior antibacterial properties. A finite element simulation process with a new approach was used to study the composite impact properties in the standard Charpy impact test; moreover, in the experimental procedure, a new method was introduced for the production of HDPE/ZnO composites without the use of the compatibilizers. Fouriertransform infrared spectroscopy (FTIR) test was used to check the diffusion of particles in composites. Field emission scanning electron microscopy (FESEM) was utilized to examine the presence of particles in composites. The results of the simulation showed that the HDPE/1%ZnO composites have the best impact resistance in comparison to other composites. Experimental results also showed that HDPE/1%ZnO composites have the best performance in terms of impact strength with an error of about 11% compared to simulation results and are economical. Moreover, the results of the antibacterial test of HDPE/1%ZnO composites confirm the excellent performance of these composites against gram-positive and negative strains.
