Polylactic acid/multi walled carbon nanotubes (PLA/MWCNT) nanocomposite for 3D printing of medical devices

In recent years, the composite nanomaterials area has had a great development impact in health sciences. Biomaterials depict as one of most promising since they are compatible with additive manufacturing (AM) techniques. It is also possible to use them mold specific medical parts. Composite have shown good biocompatibility and low toxicity benefits equal or greater than metals (i.e., Co-Cr alloy). The purpose this study develop nanocomposite biomaterial (PLA/MWCNTf) from Polylactic Acid (PLA) functionalized Multi Walled Carbon Nanotubes (MWCNTf) evidence its potential application 3D printing orthopedic fixation devices. PLA/MWCNTf was prepared by solution blending technique, incorporating proportion 0.5 wt% MWCNTf PLA matrix. TGA analysis used determine thermal stability, slight increase found compared PLA. FTIR spectroscopy confirmed presence carboxylic acid groups which improves incorporation nanotubes Additionally, Raman spectroscopy, SEM, AFM micrographs were verify reached surface homogeneously. Additive preparation done extrusion molding well printing.
