مقاله A micro initiator realized by integrating KNO3@CNTs nanoenergetic materials with a Cu microbridge : تی پی بین

خلاصه مقاله

A micro initiator was developed by integrating KNO₃@CNTs nanoenergetic materials with a Cu thin-film microbridge realized onto a glass substrate. It was fabricated by magnetron sputtering with Cu and subsequent electrophoretic deposition with KNO₃@CNTs nanoenergetic materials, which were prepared by wet chemical method, embedding KNO₃ in carbon nanotubes (CNTs). The samples were characterized by TEM, XRD, TG/DSC and SEM, respectively. The electrical explosion performances of the micro initiator under capacitor discharge were investigated. The process of electrical explosion was observed by high-speed photography and the temperature distribution versus time was acquired by a temperature measurement system with double line of atomic emission spectroscopy. The results show that the hollow cavities of the CNTs were filled with crystalline KNO₃, and that the entire surface of the micro initiator was well distributed without large reunion. Compared with single-layer Cu thin-film microbridge, the micro initiator possessed more violent electrical explosion process, the electrical explosion duration was longer, and the peak temperature was higher, which indicate that chemical reactions of KNO₃@CNTs nanoenergetic materials were involved in the electrical explosion process of the micro initiator, accompanied by more heat release.
