Title: Synthesis of energetic material particles with controlled morphology

Abstract

A surfactant-assisted self-assembly method can be used to crystallize energetic materials with controlled morphology. Microparticles of hexanitrohexaazaisowurtzitane (CL-20) formed by this method may have enhanced functional reproducibility due to their monodisperse nature, and decreased shock sensitivity due to their sub-2 μm particle size.

Metal-oxide-based energetic materials and synthesis thereof

Patent Tillotson, Thomas M. (Tracy, CA), Simpson; Randall, L [Livermore, CA]; Hrubesh, Lawrence W [Pleasanton, CA]

A method of preparing energetic metal-oxide-based energetic materials using sol-gel chemistry has been invented. The wet chemical sol-gel processing provides an improvement in both safety and performance. Essentially, a metal-oxide oxidizer skeletal structure is prepared from hydrolyzable metals (metal salts or metal alkoxides) with fuel added to the sol prior to gelation or synthesized within the porosity metal-oxide gel matrix. With metal salt precursors a proton scavenger is used to destabilize the sol and induce gelation. With metal alkoxide precursors standard well-known sol-gel hydrolysis and condensation reactions are used. Drying is done by standard sol-gel practices, either by a slowmore » « less

Controlled synthesis of hierarchically-structured hybrid materials through peptoid engineering

Patent Chen, Chun-Long

This disclosure concerns a method for making a hybrid organic/inorganic material having an architecture. The method includes combining a peptoid comprising a sequence of N-substituted glycine residues and an inorganic material or inorganic material precursor to form a hybrid organic/inorganic material comprising the peptoid and the inorganic material, the hybrid organic/inorganic material having an architecture based at least in part on the peptoid sequence. The hybrid organic/inorganic materials include a cluster of nanoparticles of an inorganic material and peptoids, the cluster formed by random attachment of nanoparticles to one another by peptoid-peptoid and peptoid-nanoparticle surface interactions, wherein the hybrid materialmore » « less
