This materials proof-of-concept study explored using radiofrequency EMF to heat magnetic nanoparticles dispersed in PLLA to modulate polymer properties. Heating was monitored by infrared camera, and polymer changes were assessed by differential scanning calorimetry and nanoindentation. The authors report that EMF…

This engineering study reports fabrication of a biodegradable PLLA shape-memory nanocomposite incorporating surface-modified Fe3O4 nanoparticles. The composite showed improved tensile/mechanical and shape-memory properties compared with PLLA, and shape recovery could be triggered by an alternating magnetic field.…
