Sustainable Electrosynthesis of Porous CuN3 Films for Functional Energetic Chips

“…178 °C and a heat output of ca. 1200 J·g –1 , both of which are associated with a rapid decomposition of CuN 3 . The TG curve shows that the mass loss of the CuN 3 film is ca.…”

“…The energetic properties of the porous CuN 3 film in this work are compared with other CuN 3 materials and summarized in Table S1. The T p of the porous CuN 3 film is lower than that of porous CuN 3 (187.7 °C) prepared by a gas–solid azidation method . A low T p indicates low initiation energy .…”

Copper Azide Nanoparticle‐Encapsulating MOF‐Derived Porous Carbon: Electrochemical Preparation for High‐Performance Primary Explosive Film

“…To overcome undesirable electrostatic sensitivity, several pioneering works have been devoted to the construction of CA-based composites by means of physical mixing of conductive materials (copper, carbon fiber, graphite, graphene, or graphene oxide) or the confinement of CA inside carbon skeletons (carbon nanotubes or porous carbon). [17][18][19][20][21] Despite these great successes, the controllable synthesis for a nanoscale uniformity of CA-based composite in film form is still highly challenging to achieve an efficient and secure MEMS-compatible primary explosive.Herein, we propose a simple, tunable, and scalable metalorganic frameworks (MOFs)-templated strategy for an in situ electrochemical preparation of a CA-based composite film. MOFs, a unique class of newly emerging porous materials assembled with metal-based nodes and organic linkers, are considered as effective self-sacrificed templates or precursors.…”

An energetic composite formed of wrinkled rGO sheets wrapped around copper azide nanowires with higher electrostatic safety as a green primary explosive

“…28 In spite of these developments, there are still few reports of an insensitive energetic composite based on CA. 29,30 Moreover, most of these methods require tedious synthesis processes and involve high costs and safety risks during preparation.…”
