Abstract

The invention relates to a preparation method of a graphene oxide-aluminum-molybdenum trioxide ternary nano-composite energy-containing film. At present, the achievement of the aim on quickly and high-efficiently assembling a multi-component thin film with high heat release in a low-cost way faces the challenge. The preparation method comprises the steps of adopting nano-aluminum powder, grapheneoxide and nano-molybdenum trioxide as depositional facies, and polymine as an additive; and adopting an electrophoretic deposition method to obtain the GO / Al / MoO3 ternary nano-composite energy-containing film. The GO / Al / MoO3 ternary nano-composite energy-containing film prepared through the invention is good in dispersibility, compact in film, and excellent in heat release performance and combustion performance. The preparation method provided by the invention not only can be used for preparing the GO / Al / MoO3 ternary nano-composite energy-containing film, but also can be used for preparing a composite film with multiple particles. The preparation method provided by the invention is simple in process short in period, low in production cost, and suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to a preparation method of a nanocomposite energetic film, in particular to a preparation method of a graphene oxide-aluminum-molybdenum trioxide ternary nanocomposite energetic film. Background technique [0002] Nano energetic materials are widely used in propellants, gunpowder and energetic ignition bridges due to their special composition and properties. As a new type of high-energy nano-energetic material, nano-thermite has the advantages of high energy density, high oxygen carrying capacity, high mass density, and wide range of component selection, which has attracted extensive attention of researchers in recent years. [0003] Among the prepared nano-thermites reported so far, Al / MoO 3 Thermite combustion rate can reach up to 1000m / s, Al / MoO 3 The theoretical heat release is 4703 J / g, which is much higher than that of common thermite materials. However, due to the constraints of various factors, the various preparation m...
