Repair of physically separated thermoplastic polymers containing γ ‐Fe 2 O 3 nanoparticles without sacrificing their mechanical properties is achieved by applying an oscillating magnetic field. As γ ‐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.
