Abstract
Free-standing block copolymer films containing magnetic iron oxide nan oclusters within the microdomains were produced by static casting. The thickness of the nanocomposite films was easily controlled to make op tically transparent thin films. The size distribution of the nanoclust ers was relatively narrow and the nanoclusters were uniformly distribu ted within the films. The spherical nanoclusters, ca. 5 nm in diameter , were identified as gamma-Fe2O3 and had a well-defined crystalline st ructure. Magnetic measurements revealed that the nanocomposite films a re superparamagnetic.
