Fabrication and Characterization of Carbon Nanotubes Composite Energetic Bridge Film
Carbon nanotubes composite energetic bridge film were fabricated on the conducting substrates by magnetron sputtering and electrophoretic deposition with carbon nanotubes composite energetic materials, which were prepared by wet chemical method, embedding KNO3 in carbon nanotubes. The samples were characterized by TEM, XRD, DSC and SEM. The electrical explosion performances of the bridge film under capacitor discharge were investigated. The process of electrical explosion was observed by high-speed photography and the time-temperature distribution was obtained by a temperature measurement system with double line of atomic emission spectroscopy. The results show that the hollow cavities of the carbon nanotubes were filled with crystalline KNO3, and that the entire surface of the bridge film was porous, fluffy and well distributed. Compared with single-layer Cu bridge film, carbon nanotubes composite energetic bridge film possessed more violent electrical explosive process, the electrical explosive duration was longer, and the peak temperature was higher, which indicate that chemical reactions were involved in the electrical explosive process of carbon nanotubes composite energetic films, accompanied by more heat release.
