Carbon Nanotube-Based Reinforced Polymers for Medical Applications: Improving Impact Strength of Polymer-Polymer Composites

There is a continuous need for innovative biomaterials with advanced properties to meet the biomechanical requirements of orthopedic implants and interventional devices. Recent research findings show that using material composites leads significantly improved properties, which are beneficial medical applications. Therefore, this work aims at studying polymer-polymer high-density polyethylene (HDPE) ultrahigh molecular weight (UHMWPE), were mixed without reinforcement multiwall carbon nanotubes (MWCNTs) in two steps. An extensive characterization workflow including mechanical tensile tests, tribological performance, surface characteristics was used analyze reinforced composite samples. The results tests showed developed MWCNT-reinforced samples achieved better due higher yield point highest sample 48.5% HDPE-50% UHMWPE-0.5% MWCNTs, value hardness test peaking 49.5% lower friction coefficient HDPE-UHMWPE-MWCNTs Overall, MWCNTs led significant improvement required designated use biopsy needles, will lead clinical results.
