Method & Evidence

AimTo investigate the impact of grafting carbon nanotubes (CNTs) onto polylactic acid (PLA) nanofibers on their mechanical and electrical properties.

MethodExperimental material synthesis and characterization.

ProcedurePolylactic acid nanofibers were oxidized to functionalize their surface, followed by grafting with carbon nanotubes. The resulting PLA-CNTs membranes were then analyzed using Scanning Electron Microscopy (SEM) for morphology and Fourier-Transform Infrared Spectroscopy (FTIR) for chemical composition. Mechanical rigidity and electrical resistivity were also measured and compared to unmodified PLA membranes.
