Repairing Polymers Using an Oscillating Magnetic Field

Repair of physically separated thermoplastic polymers containing gamma-Fe2O3 nanoparticles without sacrificing their mechanical properties is achieved by applying an oscillating magnetic field. As gamma-Fe2O3 nanoparticles oscillate at the frequency of the magnetic field, localized amorphous flow occur, and a permanent repair of physically separated polymeric films is achieved.
