Polyurethane blends with nitrocellulose/nitroglycerin: exploring thermal properties for advanced propellant formulations
This study concerns an in-depth analysis of the features of polyurethane mixed with double base noted DB (nitrocellulose/nitroglycerin) as a high-energy component. In this context, polymer blends of polyurethane/DB were prepared at various mass ratios, employing hydroxyl-terminated polyester prepolymer (Desmophen®1200) doped with nitrocellulose/nitroglycerin mixture. The formulated PU/DB blends were analyzed through Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). Moreover, the prepared samples underwent thorough thermal analysis using thermogravimetric (TG) and differential scanning calorimetry (DSC) techniques. To delve deeper into the thermal decomposition of the formulated compositions and determine related kinetic parameters, isoconversional kinetic methods such as it-KAS, it-FWO, and VYA/CE were employed. The results indicate that incorporating DB into the PU binder positively affects the PU's characteristics. This includes an increase in energy release and a catalyzed thermal decomposition process.
