Ultrasonically Accelerated Nitration of Hydroxyl-Terminated Polybutadiene: Process Efficiency and Product Characterization

open access: yesEng
Hydroxyl-terminated polybutadiene (HTPB) is widely studied and the most used prepolymer for the binder system of composite solid propellants. A suitable functionalization of HTPB with energetic groups greatly improves the performance of the propellant ...

Recyclable Dynamic Covalent Networks Derived from Isocyanate Chemistry: The Critical Role of Electronic and Steric Effects in Reversibility

open access: yesChemSusChem, Volume 18, Issue 13, July 1, 2025.
The emergence of dynamic covalent networks, featuring dynamic covalent bonds formed through isocyanate‐involved chemistry, aims to substitute conventional, non‐recyclable polyurethanes and polyureas. The review examines the reversibility of these dynamic bonds and the relevant polymer networks from the lens of electronic and steric influences.The ...

Influence of AP Particle Size on Burning Characteristics of HMX/AP Propellants Supplemented with Fe2O3

open access: yesPropellants, Explosives, Pyrotechnics, Volume 50, Issue 6, June 2025.
ABSTRACT Nitramine propellants have attracted considerable attention in the domain of solid rockets and gun propulsion because of their energetic and smokeless features. Ammonium perchlorate (AP) is the widely used oxidizer in propellants owing to the excellent burning characteristics.
