The current study examined the stabilizing effect of lignin biopolymer in comparison to traditional 2-nitrodiphenylamine (2-NDPA) and 1,3-Dimethyl-1,3-diphenylurea (C-II) stabilizers on stability double-base nitrocellulose (NC)/diethylene glycol dinitrate (DEGDN) propellant during artificial aging (at 338.65 K for 60 days). Various spectroscopic techniques, including Fourier Transform Infrared Spectroscopy (FTIR) X-ray Diffraction (XRD), were used, along with tests like Bergmann-Junk (BJ) test isothermal thermogravimetric analysis (TGA). Experimental results confirmed that FTIR XRD provided valuable insights into chemical changes aging. Particularly, lignin-stabilized NC/DEGDN exhibited comparable C-II 2-NDPA at all stages aging, as evidenced by amount released nitrous gases measured BJ thermal assessed TGA. Additionally, multivariate data using principal component (PCA) spectra successfully differentiated between aged unaged samples highlighted trends stability. Overall, findings suggest offers a propellants relative stabilizers.
