The super-hydrophobic thermite film of the Co3O4/Al core/shell nanowires for an underwater ignition with a favorable aging-resistance

Chemical Fabrication Strategies for Achieving Bioinspired Superhydrophobic Surfaces with Micro and Nanostructures: A Review

“…Moreover, strong resistance to UV irradiation was also exhibited. In 2018, Yu et al [ 132 ] constructed Co 3 O 4 precursor nanowires on Ni foil adopting hydrothermal treatment in a Teflon vessel containing Co(NO 3 ) 2 ·6H 2 O, NH 4 F, and CO(NH 2 ) 2. Then, a superhydrophobic thermite film with Co 3 O 4 /Al core/shell nanowire structures was prepared after a series of procedures involving a calcination process, magnetron sputtering deposition of Al, and low‐surface‐energy modification of 1 H ,1 H ,2 H ,2 H ‐perfluorodecyltriethoxysilane ( Figure a).…”

“…For example, fluorine-containing agents such as PFOA and fluoroalkylsilane can reduce the surface energy. [81,86,91,92,[130][131][132][133] However, fluorinated materials are harmful to the environment. [162] Nontoxic stearic acid and lauric acid are also used as a modification agent in these methods.…”

A Facile Preparation and Energetic Characteristics of the Core/Shell CoFe2O4/Al Nanowires Thermite Film

“…Such an architecture can lead to great improvements in the interfacial contact, intimacy of reactive components, and nanoscale mixing uniformity, and thus potentially boosting its energetic performances [31]. Although CuO/Al [32], Co 3 O 4 /Al [33] and NiCo 2 O 4 /Al [34] core/shell nanowire (NW) structures have demonstrated notable advantages in not only outstanding reactivity but also a significantly low activation energy. However, few investigations have been made on the core/shell nanothermite films involving other species of NWs structured metal oxides and composite metal oxides in particular.…”

Electrochemical Synthesis of Al/CuO Thermite Films on Copper Substrates

“…Nanoenergetic materials, due to their excellent spatial distribution and great interfacial contact between fuel and oxidizer, are so highly efficient as to show favorable performances in various ways including energy release, ignition, and other combustion properties. − Nanothermites, as a class of nanoscale metal-based energetic materials, consist of metal fuel (e.g., Al, Mg) and oxidizer (e.g., CuO, Fe 2 O 3 , NiO, MnO 2 , WO 3 ). Most probably benefitted from their rapid energy release rates and low ignition temperatures, nanothermites have been applied broadly in plenty of fields such as propulsions, thermal batteries, material syntheses, metal cuttings as well as blastings. − …”
