A review: Multidimensional internal plasticization of molecular structure in energetic polymer

In the field of propellant and polymer-bonded explosives (PBX), energetic polymers may bring poor mechanical properties for bulky groups and polarity. To get rid of the defects, plasticizers with low molecular weight can enhance the flexibility and processability of propellants through monotonous mixing. However, the migration of plasticizers over time may severely disrupt the mechanical property of energetic polymers. In contrast to general plasticization, internal plasticization can regulate flexibility from the perspective of molecular structure. In this context, this review focuses on the internal plasticization of energetic polymers from different dimensions. Hopefully, this review can provide some inspiration for designing energetic polymers to optimize the mechanical properties from various dimensions and integrate them for further research.
