Abstract

Repair of physically separated thermoplastic polymers containing gamma-Fe(2)O(3) nanoparticles without sacrificing their mechanical properties is achieved by applying an oscillating magnetic field. As gamma-Fe(2)O(3) nanoparticles oscillate at the frequency of the magnetic field, localized amorphous flow occur, and a permanent repair of physically separated polymeric films is achieved.
