ABSTRACT: Energetic materials (EMs) are a group of substances that can transiently release a large quantity of heat and gas by self-redox reactions, and are applied in the military and civilian field. It strictly requires to evaluate energy, safety, mechanical property, environmental adaptability, compatibility, anti-aging performance, environmental-friendliness and cost in an integral sense; meanwhile, it undergoes a high risk to operate EMs, because they are prone to react, combust and even denote once simulated sufficiently. All these increase the difficulty in create new EMs with excellent properties and performances. In fact, it is a worldwide challenge to find new excellent EMs. Compared with other materials, EMs are evolved more slowly at a lower level. The date-out research and development mode is response for the current situation. Nowadays, the creation of new EMs proceeds in a complicated and tandem way of design, synthesis, characterization, formulation manufacture, and performance evaluation. We aim to change the mode by carrying out high-throughput calculations and constructing big data base for intelligently designing new energetic molecules, find the genome groups of EMs, and accelerate the creation of new compounds. Recently, we established a high-throughput calculation plat for energetic compounds, EM studio 1.0, by which the patch-modelling of molecular structures, calculations and analyses can be automatically finished by a touch. More than 5000 moderate molecules can be dealt per day on the super-computation center of CAEP, by which two orders of computation efficiency have be achieved. In addition, a data base with > 100000 compounds will be constructed, with some important properties like density, heat of formation, bond dissociation energy and detonation properties. All these consolidate a base for intelligent design of energetic molecules in future. It is expected to accelerate the evolvement of EMs.

 

Keywords: intelligent design; high-throughput calculation; data base; EM studio 1.0.
