Carbon Nanotube (CNT) Encapsulated Magnesium-Based Nanocomposites to Improve Mechanical, Degradation and Antibacterial Performances for Biomedical Device Applications

Nowadays, magnesium (Mg) composites are gaining much attention in biomedical device applications due to their biocompatibility and biodegradability properties. This research is study the microstructure, mechanical, corrosive antibacterial properties of Mg−2.5Zn−0.5Zr/xCNT (x = 0, 0.3, 0.6, 0.9) made with mechanical alloying semi-powder metallurgy (SPM) processes, accompanied by SPS. Based on microstructural characteristics, CNTs were almost uniformly distributed Mg matrix. The results displayed that hardness ultimate compressive strength (UCS) meaningfully increased compared a Moreover, degradation rate was halved presence small amounts Kokubo simulated body fluid (SBF). Due slowed process, Mg−2.5Zn−0.5Zr/0.6CNT biocomposites exhibited excellent cellular compatibility. Evaluation activity adding matrix could significantly prevent growing Escherichia coli (E. coli) Staphylococcus aureus (S. aureus). In general, showed an efficient reinforcement for Mg−2.5Zn−0.5Zr/CNTs biocomposites, which leads improved performances.
