Abstract: Metallic nanoparticles (NPs) hold a particular interest in view of their catalysis, environmental, electronics and high frequency applications. One of the factors limiting technological applications is the small size of the batch. The electric explosion of wire (EEW) is a technique for fabrication of large amounts of NPs suitable for industrial applications. In this work we have prepared spherical Fe45Ni55, Ni, Cu and Al NPs by the EEW and fabricated polymer-NPs and polymer-NPs-thin film composites. Electron microscopy and X-ray diffraction were used for structural characterization. Following polymers were selected for fabrication of composites: butylmethacrylate resin, poly(4,4-oxydiphenylene-pyromellitimide and cycloolefine. We designed and developed the methodology for evaluation of the polymer-NPs composite structure based on scanning electron microscopy.
