Manganese molybdate nanoflakes on silicon microchannel plates as novel nano energetic material

Nano energetic materials have attracted great attention recently owing to their potential applications for both civilian and military purposes. By introducing the silicon microchannel plates (Si-MCPs) three dimensional (3D) ordered structure, monocrystalline MnMoO4 with a size of tens of micrometers and polycrystalline MnMoO4 nanoflakes are produced on the surface and sidewall of the nickel-coated Si-MCP, respectively. The MnMoO4 crystals ripen controllably forming polycrystalline nanoflakes with the lattice fringes of 0.542 nm corresponding to the (1 ̅11) plane on the sidewall. And these nanoflakes MnMoO4 shows apparent thermite performance which is rarely reported and represents MnMoO4 becomes a new category of energetic materials after nanocrystallization. Additionally, the nanocrystallization mechanism is interpreted by ionic diffusion caused by 3D structure. The results indicate that the Si-MCP is a promising substrate for nanocrystallization of energetic materials such as MnMoO4.
