An emulsion is a multiphase dispersion system in which one or more liquids are dispersed in the form of particles in another immiscible liquid. Emulsion method has been applied for preparation of binder system via oil in water (O/W) emulsions. The formulation contains: 40 g 12 % a solution of polyvinyl alcohol (PVA) in water, 15 g 7.5 % a solution of Viton A (vinylidene hexafluoropropene copolymer) in ethyl acetate, 0.25 g sodium dodecyl sulfate (SDS) and 0.25 g Tween‐80.The emulsion as a binder system, sub‐micro CL‐20 (prepared by the ball milling method) as the body explosives to prepared CL‐20 based explosive ink (CL‐20 88 % concentration). Deposition of explosive inks via DIW technology and its properties were characterized. The results showed that the composite has fewer internal defects and low impact sensitivity, the crystal type has no change, critical detonation size is around 1×0.17 mm and detonation velocity is 8079 m/s.

“…In the development of smart weapons and related equipment, energetic materials are expected to be integrated on a smaller scale into systems [ 2 , 3 ]. The application of microcomposites of explosives is thought to provide a less expensive, safer approach to the miniaturization of energetic devices and the development of pyrotechnics, propellants, and explosives [ 7 , 8 ]. Furthermore, energetic materials that can be deposited with microscopic patterns on flat substrates are essential for the development of safe Si-based initiator chips that can be used for the timed detonation of safe arm and fire (SAF) devices [ 9 , 10 ].…”

The production of energetic crystalized micro-patterns by using one-step printing has become a recent trend in energetic materials engineering. We report a direct ink writing (DIW) approach in which micro-scale energetic composites composed of 1,3,5-trinitro-1,3,5-triazinane (RDX) crystals in selected ink formulations of a cellulose acetate butyrate (CAB) matrix are produced based on a direct phase transformation from organic, solvent-based, all-liquid ink. Using the formulated RDX ink and the DIW method, we printed crystalized RDX micro-patterns of various sizes and shapes on silicon wafers. The crystalized RDX micro-patterns contained single crystals on pristine Si wafers while the micro-patterns containing dendrite crystals were produced on UV-ozone (UVO)-treated Si wafers. The printing method and the formulated all-liquid ink make up a simple route for designing and printing energetic micro-patterns for micro-electromechanical systems.

“…Based on advanced manufacturing and integration ideas, microelectronic systems, machinery systems and chemical energy systems are integrated into micro electro-mechanical systems (MEMS) with initiating function, which are also known as MEMS pyrotechnics. Using MEMS pyrotechnics technology, ignition or detonation can rely on an energetic chip with centimeter or millimeter size, which can significantly promote the miniaturization, light weight and intelligence of the weapon system [1][2][3][4][5][6]. Recently, MEMS initiating device technology has developed rapidly and has been used in micro propulsion and micro initiators [7][8][9][10][11][12][13][14][15].…”

In order to improve the mechanical strength of micro-booster based on 3,4-dinitrofurazanofuroxan (DNTF), 2,4-toluene diisocyanate (TDI) was introduced into the composite binder of nitrocotton (NC) and glycidyl azide polymer (GAP). A full-liquid explosive ink containing DNTF, binder and solvent was printed layer by layer. By the polymer cross-linking technology, the inkjet printed sample with three-dimensional network structure was obtained. The morphology, crystal form, density, mechanical strength, thermal decomposition and micro scale detonation properties of the printed samples were tested and analyzed. The results show that the printed sample has a smooth surface and a dense internal microstructure, and the thickness of the single layer printing is less than 10 μm. Compared with the raw material DNTF, the thermal decomposition temperature and activation energy of the printed samples do not change significantly, indicating better thermal stability. The addition of curing agent TDI increases the mechanical properties and charge density of the energetic composites. The elastic modulus and hardness are increased by more than 20%. The charge density can attain 1.773 g·cm−3, which can reach 95.5% of the theoretical density. The critical detonation size of the sample can reach 1 mm × 0.01 mm or less and the detonation velocity can achieve 8686 m·s−1, which exhibits excellent micro-scale detonation ability.
