Preparation of Ni nanoparticle mono-layer on polyimide substrate

Nanoparticles were produced on polyimide (PI) film through oxidation of a Ni/sub 80/Fe/sub 20/ thin film on a PI precursor layer during its imidization reaction. Film properties were investigated through transmission electron microscopy, electron diffraction and X-ray photoemission spectroscopy. The size and shape of embedded and exposed particles were compared and it was verified that the exposed particles can be effectively used as a growth template for nano-sized structures.
