Overview

This analysis demonstrates improved mechanical properties and shape memory effects in thermoplastic polyurethane composites with carbon nanotubes, suggesting advancements in fused deposition modeling.

Key Points

  • The maximum tensile strength of the composites was measured at 26.7 MPa, indicating notable enhancement in mechanical properties due to carbon nanotube integration.
  • Shape fixation and recovery ratios improved to over 99% and 93% respectively, revealing significant shape memory effects in the composites.
  • Fused deposition modeling effectively utilized the TPU and CNTs composites, optimizing performance through additional thermal responsiveness during printing.
  • Photothermal conversion capabilities were enhanced by carbon nanotubes, guiding the development of novel 4D printing applications with intelligent responsiveness.
