An Overview of the Properties of Energetic Plasticizer Based on Azido-esters

Recently, approach in the field of design and manufacture of the propellant and explosive has led to the use of energetic ingredients instead of inert. Introduction of energetic plasticizers as a replacement of commonly used inert plasticizers is another approach to improve the energy level of propellants. In this meantime, energetic compound based on organic azids were attracting a lot of attention. The poor mechanical properties of energetic binders based on an azide functional group like GAP can be improved markedly by incorporation of energetic azido functional plasticizers. Among the azide based energetic compound that are used as energetic plasticizers, azido-esters because of their better plasticizing effect has drawn much attention In recent years and several compounds based on them as energetic plasticizers were synthesized and reported in Articles. In this paper, we introduce the synthesized azido-ester plasticizers, review their properties, their synthesis methods and study the effect of structural parameters on the properties of this type of plasticizers.
