Preparation Of Energetic Nanopowders
Abstract
A method has been developed to prepare energetic nanopowders and nanocomposites using energetic inorganic nanoparticles. Technical description: In pursuit of developing effective methods to prepare energetic nanopowders and nanocomposites, crash precipitation of a solution of materials of interest is used to obtain nanosized end-products in which there is an intimate mixing between the components in the nanosized composites. The method not only produces nanosized particles, but the particles are homogeneously mixed and distributed, thereby enhancing performance (i.e., the diffusion distance between oxidizer and fuel is significantly reduced). The method can be used to prepare any nanosized materials of interest (along with the proper solvent systems), and nanosized composites with desired components and compositions. Performance data do not exist at this time. However, it is understood that the size and shape of materials affect the performance characteristics of explosives. This method allows for explosive materials to be optimized by size and shape.
Application(s)
Skin care products
Oil Industry
Advantages
Skin care products (e.g., creams, sunblock). Nanoparticles potentially absorbed more deeply into the skin than currently, because current methods do not create nanoparticles that are as well mixed together. However, this would need to be tested. Oil Industry: oil well completion service companies might be interested in using this method to enhance performance of their oil well perforators. This method could allow oil companies to extract oil faster, more cheaply, and in higher quantities, because they would be able to better control the explosions used to perforate rock beds containing oil.
