Impregnating the cores of triblock‐copolymer nanotubes with Fe 2 O 3 renders them superparamagnetic. The resultant polymer/Fe 2 O 3 hybrid nanofibers (see TEM image) have interesting properties in magnetic fields. The nanofibers align themselves in the magnetic‐field direction, and mixtures of the nanofibers and nanotubes undergo phase separation.
